Description

  The present invention relates to a power control system, a power control method, and a program.

  As a technique for reducing the power consumed by the electrical equipment (common equipment) in the building, there is a common equipment management method described in Patent Document 1.

  In the common facility management method described in Patent Document 1, information indicating whether or not an individual area used as a tenant (an individual area for which a user has an exclusive right) is in a locked state is used to control an electrical facility. Collect with control computer. When the collected information indicates the locked state, the control computer stops the electrical equipment disposed in the individual area indicating the locked state. Thereby, the electric power consumed by the electric equipment of the individual area | region in a locked state is reduced, and the electric power consumed by the electric equipment in a building is reduced.

JP 60-147804 A

  In the common facility management method described in Patent Document 1, the power consumed by the electrical equipment in the individual area in the locked state is reduced, but no control is performed on the electrical equipment in the individual area that is not in the locked state. Therefore, for example, when there is a limit on the total power consumed in the building, such as a power usage restriction order based on Article 27 of the Electricity Business Law, the above-mentioned common facility management method is used. The only way to reduce the power consumption is to reduce the power consumed by electrical equipment in individual areas that are not locked.

  However, tenants who use individual areas include, for example, hospitals where medical equipment is placed and supermarkets where freezers are placed. Therefore, power consumed by electrical equipment placed in such individual areas is reduced. Then, there was a problem that inconveniences such as inability to perform medical practice or inability to freeze food.

  The present invention has been made in view of the above circumstances, and it is possible to reduce inconvenience that may occur in the electrical equipment arranged in the individual area after suppressing the total power consumed in the electrical equipment within the upper limit value. An object of the present invention is to provide a power control system, a power control method, and a program.

  In order to achieve the above object, an electric power control system according to the present invention is an electric facility arranged in an individual area that can be used exclusively by a user, and is an area different from the individual area. It controls the electric power consumed by the electric equipment arranged in the common area that can be used jointly. The power setting unit sets an upper limit value of the total power consumed by the electrical equipment. The required power storage unit stores the power required for the operation of the electrical equipment arranged in the individual area as the required power for each electrical equipment in the individual area. When the shortage specifying unit distributes the upper limit value of the total power set by the power setting unit between the electrical equipment corresponding to each required power stored in the required power storage unit and the electrical equipment arranged in the common area Identify electrical equipment in individual areas where required power cannot be secured. The reduction supply unit reduces the power supplied to the electrical equipment placed in the common area when the shortage identification part identifies the electrical equipment in the individual area where the required power cannot be secured. Supply to electrical equipment in individual areas where power cannot be secured.

  According to the present invention, when the upper limit value of the total power consumed by the electrical equipment is distributed between the electrical equipment corresponding to each required power and the electrical equipment arranged in the common area, the individual area where the required power cannot be secured. When there is an electrical facility, the power supplied to the electrical facility arranged in the common area is reduced, and the reduced amount is supplied to the electrical facility in the individual area where the required power cannot be secured. As a result, in order to suppress the total power consumed by the electrical equipment within the upper limit, compared to a system that uniformly reduces the power consumed by the electrical equipment, the electrical equipment in an individual area where the required power cannot be secured. Occurrence can be reduced. Therefore, it is possible to reduce inconveniences that may occur in the electrical equipment arranged in the individual areas while suppressing the total power consumed in the electrical equipment within the upper limit value.

(First embodiment)
Hereinafter, a power control system 10 according to a first embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the power control system 10 includes a power control device 20, operation units 50 ₁ to 50 ₇ that operate electrical equipment 55 _{1 to} 55 ₇ (see FIG. 2), and measurement units 60 _{1 to} 60 _7. When provided with a main terminal 70, and the sub-terminal ₈₀ 1 to 80 _4.

The power control system 10 uses, for example, the upper limit of the total power consumed (usable) in the electrical equipment in the building 100 shown in FIG. 2 as the individual area R1 that consumes the power (required power) necessary for operation. the electrical equipment ₅₅₁ to 554 ₄ to R4, when partitioned between electrical equipment ₅₅ 5-55 ₇ shared region C1 to C3, when there is electrical equipment of the individual regions can not be secured in the required power is, the common area This is a system that reduces the power consumed by the installed electrical equipment and supplies the reduced power to the electrical equipment in an individual area where the required power cannot be secured. The power control system 10 by a series of the above-described control, specifically, the power consumed (used) in electrical equipment ₅₅ 5-55 ₇ shared areas C1 to C3, individually required power can not be secured area R1~R4 the control of flexibility to the electrical equipment ₅₅₁ to 554 _4, hereinafter referred to as "power interchange".

  The individual area means an area that can be used exclusively by the user, and the common area means an area that is different from the individual area and can be used jointly by persons other than the user. ing.

  As shown in FIG. 2, the building 100 is, for example, a three-story commercial building. On the first and second floors, for example, individual areas R4, R3 used as a hospital or a supermarket, and a common area C3, C2 is laid out. On the third floor, for example, two individual areas R1 and R2 used as an office and a shared area C1 are laid out.

The individual area R1~R4 building 100, is installed electrical equipment ₅₅₁ to 554 _4, respectively, in the shared area C1~C3 are electrical equipment ₅₅ 5-55 ₇ are respectively installed. Each of the electrical equipment 551 _to 554 _7, including for example various facilities typified air conditioning or lighting equipment. In this embodiment, for convenience of explanation, it is collectively the various equipment installed in individual area R1~R4 and shared area C1~C3 for each area, and displays the electrical equipment ₅₅₁ to 554 _7.

  Returning to FIG. The power control device 20 of the power control system 10 includes a control unit 21, a main storage unit 31, an auxiliary storage unit 41, an interface unit 49, and a bus line BL, and controls the power system 10.

  The control unit 21 includes a CPU (Central Processing Unit) 22 and a ROM (Read Only Memory) (not shown), and controls each of the units 31, 41, 49 using various information received via the bus line BL. .

  The CPU 22 executes a program stored in the ROM (for example, processing shown in flowcharts of FIGS. 7 to 12 described later).

  In addition, the control unit 21 executes a program stored in the ROM by the CPU 22, whereby a power setting unit 23, a suppliable power calculation unit 24, a shortage specifying unit 25, a reduction supply unit 26, and a power consumption determination unit. 27 and the current power saving unit 28 are realized.

Power setting unit 23 is consumed by the electrical equipment ₅₅₁ to 554 ₇ building 100 (available) to calculate the upper limit value of the total power, set the power storage unit 44 (storage). The upper limit value of the total power is normally the maximum power used notified by the Ministry of Economy, Trade and Industry when a contract power or a power usage restriction order based on Article 27 of the Electricity Business Law is issued. However, in the event of an emergency, such as when a shortage of power supplied by the power company is expected and an emergency request for power reduction cooperation has been made by the government, the upper limit of the total power will be a fixed power from the contract power (maximum power used). The value is deducted. In an emergency, the power setting unit 23 subtracts the power corresponding to the emergency reduction rate input using the main terminal 70 from the contract power (the maximum power used), and sets this as the upper limit value of the total power. It is to do. The upper limit value of the consumed (usable) power set by the power setting unit 23 is hereinafter referred to as consumable power.

Available power calculation unit 24, the individual regions R1 to R4, for each of each of the electrical equipment ₅₅₁ to 554 ₇ shared areas C1 to C3, and calculates a suppliable maximum power (available power). In the case where power interchange is not running, available power calculation unit 24, for electrical equipment 551 _to 554 ₄ of the individual areas R1 to R4, calculated as available power contract power for each individual area , the electrical equipment ₅₅ 5-55 ₇ shared area C1~C3 calculates power which is previously determined for each common region as available power.

  On the other hand, when power interchange is executed, the suppliable power calculation unit 24 calculates suppliable power by a calculation method different from that described above. Specifically, the suppliable power calculation unit 24 uses a calculation method different from the above in the case of power interchange start (before initial value calculation) and in the case of power interchange execution (after initial value calculation). Calculate the power that can be supplied.

In the case of power interchange start (before initial value calculation), the suppliable power calculation unit 24 calculates suppliable power (initial value) as follows. In other words, available power calculation unit 24, first, a consumable power set by the power setting unit 23 (the upper limit of the total power), is pre-determined by the electrical equipment ₅₅ 5-55 ₇ shared area C1~C3 Subtract the power that is present. Next, the suppliable power calculation unit 24 distributes the subtracted power evenly among the electrical facilities 55 _{1 to} 554 in the individual regions R _{1 to} R ₄ . After that, the suppliable power calculation unit 24 ends the distribution for the individual area that has become the required power, and continues the distribution until the upper limit is reached for the individual area for which the required power cannot be secured. In this manner, available power calculation unit 24, the electrical equipment ₅₅₁ to 554 ₄ of the individual areas R1 to R4, for each of the electrical equipment ₅₅ 5-55 ₇ shared areas C1 to C3, the supply at the start of power interchange The possible power (initial value) is calculated. At the time of calculating the initial value, an individual area where the required power cannot be secured is a target for which power can be accommodated.

Further, during power interchange (after initial value calculation), the suppliable power calculation unit 24 calculates suppliable power as follows. That is, the power interchange executed after the initial value calculation, is reduced available power of the electric equipment 55 _{5-55 7} shared area C1~C3 is, the supply of the reductions can not be ensured the required power discrete areas of electrical equipment When added to the electric power, available power calculation unit 24, the individual regions R1 to R4, for each of the electrical equipment ₅₅₁ to 554 ₇ shared areas C1 to C3, and calculates the available power. In this way, the suppliable power calculating unit 24 sets the electric facilities 55 _{1 to} 55 ₄ in the individual areas R _{1 to} R ₄ and the electric facilities 55 _{5 to} 55 _{7 in} the common areas C _{1 to} C ₃ each time execution of power interchange is performed. For each, the suppliable power is calculated repeatedly.

  The shortage specifying unit 25 specifies an individual area where power accommodation is necessary. Specifically, the shortage specifying unit 25 determines the supplyable power calculated by the supplyable power calculation unit 24 and the power (required power) necessary for the operation of the electrical equipment in the individual area for each electrical equipment in the individual area. In comparison, the electrical equipment in the individual area where the power that can be supplied is less than the required power is specified.

Reduction supply unit 26, the determination in power interchange running (after initial value calculation), available electric power of the electric equipment 55 _{5-55 7} shared region C1~C3 is (or has exceeded the lower limit) or can be reduced To do. The reduction supply unit 26 has determined that it is possible to reduce, to reduce the available power of the electric equipment 55 _{5-55 7,} the reductions, the electrical equipment of the identified discrete region due to lack certain unit 25 Add to available power. By the control of the reduction supply unit 26, the suppliable power of the electric equipment in the common area decreases, while the suppliable power of the electric equipment in the individual area that has received power interchange increases.

When the power interchange is completed, the used power determining unit 27 converts the suppliable power calculated by the suppliable power calculating unit 24 into the electric facilities 55 _{1 to} 55 of the individual areas R1 to R4 and the shared areas C1 to C3. ₇ determines the power that can be used (consumed). In individual areas R1 to R4, the electrical equipment ₅₅₁ to 554 ₇ shared areas C1 to C3, can be the upper limit power use power determining unit 27 is determined, using the power (consumption).

  When the supply power of the electric equipment in the common area is reduced by the control of the reduction supply unit 26 and the reduced available power is determined to be usable (consumed) by the use power determination unit 27, The electrical equipment keeps the power consumption at the upper limit as follows. That is, if the electric equipment in the common area is, for example, a vending machine such as a beverage or ice cream, the power consumption is kept at the upper limit by raising the temperature of refrigeration / freezing or darkening the lighting. Further, if the electric equipment in the common area is a lighting equipment, the power to be consumed is kept at the upper limit by reducing the number of lights to be lit (thinning the lights to be lit). Further, if the electric equipment of the shared equipment is an air conditioner, the power consumption is kept at the upper limit by increasing the set temperature during cooling (lowering the set temperature during heating) or stopping the operation.

Accept. When it is accepted that the form of power interchange is urgent, the CPU 22 sets the input part of the emergency reduction rate on the setting screen IM1 so that it can be input. On the other hand, when it is accepted that the form of power interchange is normal, the CPU 22 sets the input part of the emergency reduction rate on the setting screen IM1 to be unusable.

  The input part (pull-down part) of the emergency reduction rate on the setting screen IM1 is a reduction from the contract power (maximum power used) stored in the contract power storage unit 42 when it is accepted that the form of power interchange is urgent. The input of the urgent reduction rate which becomes a rate is received. When the emergency reduction rate input is accepted, the CPU 22 stores the accepted reduction rate in the emergency reduction rate storage unit 43.

  Returning to FIG. The power interchange execution unit 72 displays an instruction reception screen for causing the power control system 10 to execute power interchange on the display unit 70a, and receives the instruction from the user via the screen. When the power interchange execution unit 72 receives an instruction to execute power interchange from the user, the power interchange execution unit 72 notifies the CPU 22 of the reception. Then, the CPU 22 starts executing power interchange by the power control system 10.

Returning to FIG. The sub terminals 80 ₁ to 80 ₄ are installed in the individual areas R ₁ to R ₄ of the building 100, respectively. Each of the sub terminals 80 ₁ to 80 ₄ has a display unit 80a and an input unit 80b.

  The display unit 80a includes a CRT (Cathode Ray Tube) or an LCD (Liquid Crystal Display).

  The input unit 80b includes an input device such as a keyboard or a pointing device such as a mouse. An instruction to the power control system 10 is input via the input unit 80b and notified to the control unit 21 via the interface unit 49 and the bus line BL.

  As shown in FIG. 5, the input unit 80 b realizes functions of a normal setting unit 81 and an emergency setting unit 82 by operating a keyboard, a mouse, and the like. Note that when the user instructs a setting at the time of power interchange by operating a keyboard, a mouse, or the like, the CPU 22 operates the normal setting unit 81. On the other hand, when the user has instructed the setting at the time of emergency power interchange, the CPU 22 operates the emergency setting unit 82.

The normal setting unit 81 requests the CPU 22 to display the normal setting screen IM2 shown in FIG. 6A on the display unit 80a, displays the maximum power used on the normal setting screen IM2, and further reduces it. Accept from users of time zone and reduction rate. In FIG. 6 (a) (b), illustrates the setting screen displayed on the display unit 80a of the sub-terminal 80 ₄ disposed in the individual area R4.

  The maximum power usage display portion (square box portion) of the normal setting screen IM2 displays the maximum power usage for the same period and the same time period of last year.

  The input portion (pull-down portion) of the reduction time zone on the normal setting screen IM2 accepts the input of the time zone that maintains the normal reduction rate input to the normal reduction rate input portion of the normal setting screen IM2.

  When this reduced time zone is input, the CPU 22 reads the maximum power consumption of the individual area R4 stored in the past power consumption storage unit 46 in the same period / same time zone as last year, and sets it as a normal setting. Displayed on the display portion of the maximum power used on the screen IM2.

  Here, if it is less than one year since moving into the individual area, and the maximum power used in the same period / same time period of last year is not stored in the past power consumption storage unit 46, the CPU 22 Is read from the past power consumption storage unit 46 and displayed on the display portion of the maximum power usage on the normal setting screen IM2.

  The input part of the normal reduction rate on the normal setting screen IM2 accepts the input of the power reduction rate (normal reduction rate) when the power interchange mode is normal. This normal reduction rate is based on the power displayed in the maximum power consumption portion of the normal setting screen IM2, that is, the individual region R4 stored in the past power consumption storage unit 46 in the same period / same time period of last year. The reduction rate is based on the maximum power used.

When the input of the reduction time zone and the normal reduction rate is completed on the normal setting screen IM2, the CPU 22 calculates the power using the maximum power used and the normal reduction rate during the same period and the same time period last year. Then, CPU 22 stores the calculated power, as the required power of the electric equipment 55 ₄ discrete regions R4, in association with the reduction time zone is stored in the normally required power storage unit 47.

Specifically, the CPU 22 subtracts the normal reduction rate from 100, and integrates the value with the maximum power used in the same period / same time period as last year. Then, CPU 22 associates a reduced time period and the accumulated value, the required power in the electrical equipment 55 ₄ individual region R4.

For example, as shown in FIG. 6 (a), the maximum use power of the individual region R4 in the same period / same time period of last year is 2400 Wh, and the reduction time period is input as 12: 0 to 14:00, When the reduction rate is input as 15%, first, the CPU 22 performs 2400 × (100−15) and calculates 2040 Wh. Next, the CPU 22 associates 2040 Wh with the reduction time zone 12: 0 to 14:00. Then, CPU 22 is required power of the electric equipment 55 ₄ individual regions R4 is 12:00 to 14:00 between, when is 2040Wh, is normally stored in the required power storage unit 47.

Note that the reduction time zone of the usual setting screen IM2, since it is possible to input a plurality of time zones, with the sub-terminal 80 ₄ discrete regions R4, reduced time period, in addition to the time zone above For example, it is also possible to input 14: 0 to 16:00 and 16: 0 to 17:00. In this case, the normal reduction rate can be input for each of the two time zones described above. When the normal reduction rate is further input, the CPU 22 sets the required power between 14:00:00 and 16:00 and the required power between 16:00 and 17:00 between 12:00:00 and 14:00. In addition to the required power, the normal required power storage unit 47 stores it. With this configuration, the CPU 22 can store the required power different for each time zone in the normal required power storage unit 47 for each electrical facility in the individual area.

  The emergency setting unit 82 requests the CPU 22 to display the emergency setting screen IM3 shown in FIG. 6B on the display unit 80a, displays the current power consumption on the emergency setting screen IM3, and further reduces the power consumption. Accept from users of time zone and emergency reduction rate.

  The current power consumption display portion (square box portion) of the emergency setting screen IM3 displays the power currently consumed (used).

  The input part (pull-down part) of the reduction time zone on the emergency setting screen IM3 accepts the input of the time zone for maintaining the emergency reduction rate input to the emergency reduction rate input part, as in the case of the normal setting screen IM2.

  When this reduced time zone is input, unlike the case of the normal setting screen IM2, the CPU 22 reads the current power consumption of the individual area R4 stored in the past power consumption storage unit 46 and stores it as an emergency. It is displayed on the display portion of the current power consumption on the setting screen IM3. Note that the current power consumption is displayed based on the current power consumption in the event of an emergency such as a power supply shortage expected from a power company and an urgent request for power reduction cooperation from the government. This is because reductions must be made.

  The input part (bull-down part) of the emergency reduction rate on the emergency setting screen IM3 accepts the input of the power reduction rate (emergency reduction rate) when the power accommodation mode is urgent. This emergency reduction rate is based on the power displayed in the current power consumption display portion of the emergency setting screen IM3, that is, as described above, the reduction rate based on the current power consumption.

When the input to the reduction time zone and the reduction rate portion is completed on the emergency setting screen IM3, the CPU 22 calculates the required power using the current power consumption and the emergency reduction rate. Then, CPU 22 stores the calculated power, as the required power of the electric equipment 55 ₄ discrete regions R4, in association with the reduction time period, and stores the emergency request power storage unit 48.

  Note that the CPU 22 causes the emergency required power storage unit 48 to store different required power for each time zone, for each electrical facility in the individual area, as with the normal required power storage unit 47. Therefore, the details of the required power stored in the emergency required power storage unit 48 are omitted.

  Next, a setting process executed by the control unit 21 (CPU 22) when an operation by the user is performed at the input unit 70b of the main terminal 70 and an operation of the setting execution unit 71 is instructed by the user of the main terminal 70. Will be described with reference to the flowchart of FIG.

  First, the control unit 21 (CPU 22) displays a setting screen IM1 (see FIG. 4) on the display unit 70a (step S1), and accepts setting of contract power (maximum power used) (step S2). If control part 21 (CPU22) judges with acceptance of contract power (maximum use electric power) not completed (Step S3: No), it will return to Step S2. On the other hand, if the control part 21 (CPU22) determines with acceptance of contract electric power (maximum use electric power) having been completed (step S3: Yes), it will transfer to step S4.

  In step S4, the control unit 21 (CPU 22) accepts the setting of the shared minimum power (step S4). When the CPU 22 determines that acceptance of the shared minimum power is not completed (step S5: No), the CPU 22 returns to step S4. On the other hand, if it judges with control part 21 (CPU22) having received acceptance of shared minimum electric power (Step S5: Yes), it will shift to Step S6.

  In step S6, the control unit 21 (CPU 22) accepts the setting of the form of power accommodation executed by the power control system 10 (step S6). When the control unit 21 (CPU 22) determines that the acceptance of the form of power interchange has not been completed (step S7: No), the process returns to step S6. On the other hand, if the control part 21 (CPU22) determines with the reception of the form of power interchange completed (step S7: Yes), it will transfer to step S8.

  In step S8, the control unit 21 (CPU 22) determines whether or not the form of power accommodation accepted in step S6 is normal (step S8). When the control unit 21 (CPU 22) determines that the accepted form of power interchange is not normal, that is, urgent (step S8: No), it accepts the setting of the emergency reduction rate (step S9).

  Thereafter, when the control unit 21 (CPU 22) determines that the acceptance of the emergency reduction rate is not completed (step S10: No), the process returns to step S9. On the other hand, if the control unit 21 (CPU 22) determines that acceptance of the emergency reduction rate is completed (step S10: Yes), the setting process is terminated.

  In addition, also when it determines with the control part 21 (CPU22) having received the form of the power accommodation normal in step S8 (step S8: Yes), this setting process is complete | finished.

Next, it is performed the operation at the input section 80b of the sub-terminal ₈₀ 1 to 80 ₄ is set in the power interchange is performed by the control unit 21 (CPU 22) when instructed by the user of the sub-terminal ₈₀ 1 to 80 ₄ The setting process will be described with reference to the flowchart of FIG.

  First, the control unit 21 (CPU 22) determines whether the user's operation using the input unit 80b is a normal power accommodation setting or an emergency power accommodation setting (step S21). When the control unit 21 (CPU 22) determines that the user's operation is a normal power interchange setting (step S21: Yes), the control unit 21 (CPU 22) displays the setting screen IM2 (see FIG. 6A) on the display unit 80a ( Step S22) and the process proceeds to step S24.

  On the other hand, when the control unit 21 (CPU 22) determines that the user's operation was an emergency power interchange setting (step S21: No), the setting screen IM3 (see FIG. 6B) is displayed on the display unit 80a. (Step S23), the process proceeds to Step S24.

  In step S24, the control unit 21 (CPU 22) accepts the setting of the reduction time zone (step S24). If the CPU 22 determines that acceptance of the reduction time zone has not been completed (step S25: No), the CPU 22 returns to step S24. On the other hand, if the control part 21 (CPU22) determines with the reception of the reduction time zone having been completed (step S25: Yes), it will transfer to step S26.

  Thereafter, the CPU 22 accepts the setting of the reduction rate (step S26). If control part 21 (CPU22) judges with acceptance of a reduction rate not being completed (Step S27: No), it will return to Step S26. On the other hand, when the control unit 21 (CPU 22) determines that the acceptance of the reduction rate has been completed (step S27: Yes), the setting process ends.

  Next, a power interchange process executed by the control unit 21 when an operation by the user is performed at the input unit 70b of the main terminal 70 and the operation of the power interchange execution unit 72 is instructed by the user of the main terminal 70. This will be described with reference to the flowchart of FIG.

  The control unit 21 (CPU 22) displays a screen for accepting a power interchange execution form on the display unit 70a, and accepts a power interchange execution form (step S41). If the control unit 21 (CPU 22) determines that acceptance of the form of power interchange has not been completed (step S42: No), it returns to step S41.

  On the other hand, if the control unit 21 (CPU 22) determines that acceptance of the form of power interchange has been completed (step S42: Yes), the emergency flag 35 if the execution form of power accommodation accepted in step S41 is normal. Is turned off, and if the execution mode of power interchange accepted in step S41 is emergency, the emergency flag 35 is set on (step S42: Yes), and the process proceeds to step S43.

  In step S43, the control unit 21 (CPU 22) performs initial setting (step S43). Specifically, the control unit 21 (CPU 22) assigns 1 to a variable N used in the subsequent steps, and turns off all of the first shortage flag 32 to the third shortage flag 34. Furthermore, the control unit 21 (power setting unit 23) sets consumable power according to the state of the emergency flag 35 (step S43).

Thereafter, the control unit 21 (available power calculation unit 24) calculates the available power of the electrical equipment ₅₅₁ to 554 ₇ discrete regions R1~R4 and shared areas C1 to C3 (initial value) (step S44).

More specifically, the control unit 21 (available power calculation unit 24), first, a consumable power set by the power setting unit 23, is predetermined by the electrical equipment ₅₅ 5-55 ₇ shared area C1~C3 Subtract the power you have. Next, the suppliable power calculation unit 24 distributes the subtracted power evenly among the electrical facilities 55 _{1 to} 554 in the individual regions R _{1 to} R ₄ . After that, the suppliable power calculation unit 24 ends the distribution for the electrical equipment in the individual area that has become the required power, and for the electrical equipment in the individual area where the required power cannot be secured, the consumable power (the upper limit of the total power) Distribution is continued until (value) is reached. In this manner, available power calculation unit 24, the electrical equipment ₅₅₁ to 554 ₄ of the individual areas R1 to R4, for each of the electrical equipment ₅₅ 5-55 ₇ shared areas C1 to C3, the supply at the start of power interchange The possible power (initial value) is calculated (step S44).

  Thereafter, the control unit 21 (the shortage specifying unit 25) determines whether or not there is an electrical facility in an individual area where the required power cannot be secured on the Nth floor (N is any one of 1 to 3) (step S45). ).

  Specifically, the control unit 21 (insufficient identification unit 25) compares the suppliable power calculated by the suppliable power calculation unit 24 and the required power required for the operation of the electrical equipment in the individual areas for each individual area. Then, it is determined whether or not there is an electrical facility in an individual area where the required power cannot be ensured (an individual area where the suppliable power is less than the required power) (step S45). In step S45, if the emergency flag 35 is off, the control unit 21 (insufficient identification unit 25) uses the required power stored in the normal request power storage unit 47, and if the emergency flag 35 is on. The required power stored in the emergency required power storage unit 48 is used.

  When the control unit 21 (insufficient identification unit 25) determines that there is an electrical facility in an individual area where the required power cannot be secured (step S45: Yes), the control unit 21 (reduction supply unit 26) determines the Nth (N is 1). -3) whether the electric power that can be supplied to the electric equipment in the common area on the floor can be reduced, that is, the electric power that can be supplied to the electric equipment in the common area on the Nth floor is stored in the common minimum power storage unit 45 It is determined whether or not the stored minimum power is exceeded (step S46).

  When the control unit 21 (reduction supply unit 26) determines that the suppliable power of the electrical equipment in the shared area on the Nth floor exceeds the minimum power stored in the shared minimum power storage unit 45 (step S46). : Yes), the electric power that can be supplied to the electric equipment in the common area on the Nth floor is reduced by a predetermined amount (for example, 200 W), and the reduction amount of the electric equipment in the individual area on the Nth floor where the required power cannot be secured. It adds to the power which can be supplied (step S47).

  By this step S47, the control unit 21 (reduction supply unit 26) secures the required power by reducing the suppliable power of the electrical equipment in the common area on the Nth (N is one of 1 to 3) floors. Increase the power that can be supplied to the individual area on the Nth floor.

  When the control unit 21 (reduction supply unit 26) completes the execution of step S47, the control unit 21 (insufficient identification unit 25) executes steps S45 and S46 again.

If the control unit 21 (the shortage specifying unit 25) determines in step S45 that there is no electrical facility in the individual area where the required power cannot be secured on the Nth (N is any one of 1 to 3) floor (step S45). : No), the process proceeds to step S49. In step S45 again, the control unit 21 (missing a specific part 25), compares the electrical equipment ₅₅₁ to 554 ₄ available power and power required in the individual area R1~R4 at present, for each electrical equipment Then, it is determined whether or not there is an electric facility in an individual area where the suppliable power is less than the required power (step S45).

  Moreover, the control part 21 (insufficient specification part 25) determines with Yes by step S45, and can supply electric power of the electrical equipment of the common area in the Nth (N is one of 1-3) floor in step S46. However, when it is determined that the power is equal to the minimum power stored in the shared minimum power storage unit 45 (step S46: No), to indicate that there is an electrical facility in an individual area where the required power cannot be secured on the Nth floor. Then, the corresponding Nth shortage flag (any one of the first to third shortage flags 32 to 34) is turned on (step S48). Thereafter, the control unit 21 (shortage identifying unit 25) proceeds to Step S49.

  In step S49, the control unit 21 (insufficient identification unit 25) determines whether or not there is an electrical facility in an individual area where the required power cannot be secured on all floors, that is, whether the variable N is 3. (Step S49). When the control unit 21 (insufficient identification unit 25) determines that all floors have not been confirmed (step S49: No), the variable N is incremented by 1 (step S50), and the process returns to step S45. On the other hand, if the control part 21 (insufficient specification part 25) determines with having confirmed in all the floors (step S49: Yes), it will transfer to step S51.

  In step S51, the control unit 21 (reduction supply unit 26) determines whether or not any one of the first to third shortage flags 32-34 has an ON flag, that is, the individual area where the required power cannot be secured. It is determined whether there is at least one electrical facility (step S51).

  When the control unit 21 (reduction supply unit 26) determines that at least one of the first to third shortage flags 32 to 34 is on (step S51: Yes), the control unit 21 (reduction supply unit 26) is an individual region in which the required power cannot be secured. It is determined that there is at least one electric facility, and step S52 is executed in order to prevent a shortage of suppliable power in a specific individual area among them.

In step S52, the control unit 21 (reduction supply unit 26) uses all the individual regions R1 to R4 so as to obtain the same reduction rate based on the current suppliable power for the electrical equipment in each individual region. between the electrical equipment ₅₅₁ to 554 _4, adjusted to reduce and increase the available power (step S52) in the. Thereafter, the control unit 21 (reduction supply unit 26) proceeds to step S53.

In addition, if the control part 21 (reduction supply part 26) determines with all the 1st-3rd shortage flags 32-34 being OFF by step S51 (step S52: No), all the separate area | regions R1-R4. available power of the relative electrical equipment ₅₅₁ to 554 ₄ is determined to satisfy the required power, the process proceeds to step S53.

In step S53, the control unit 21 (using power determination unit 27), discrete areas R1 to R4, the available electric power of the current to the electrical equipment ₅₅₁ to 554 ₇ shared areas C1 to C3, electrical equipment ₅₅ to 554 ₇ Is determined to be usable (consumed) power (step S53). Thus, the electrical equipment 551 _to 554 _7, can be the upper limit power use power determining unit 27 is determined, using the power (consumption).

  Thus, when there is an electrical facility in an individual area where the required power cannot be secured, the operation up to step S53 reduces the power used (consumed) in the electrical facility in the common area, It can be supplied to electrical equipment in individual areas where required power cannot be secured.

  When the electric power that can be supplied to the electrical equipment in the common area is reduced by the control of the reduction supply unit 26 and the reduced electric power that can be supplied is determined to be usable (consumed) by the power usage determining unit 27, The electrical equipment keeps the power consumption at the upper limit as follows. That is, if the electric equipment in the common area is, for example, a vending machine such as a beverage or ice cream, the power consumption is kept at the upper limit by raising the temperature of refrigeration / freezing or darkening the lighting. Further, if the electric equipment in the common area is a lighting equipment, the power to be consumed is kept at the upper limit by reducing the number of lights to be lit (thinning the lights to be lit). Further, if the electric equipment of the shared equipment is an air conditioner, the power consumption is kept at the upper limit by increasing the set temperature during cooling (lowering the set temperature during heating) or stopping the operation.

Next, the control unit 21 (CPU 22) executes the setting process (see FIG. 7) by operating the input unit 70b of the main terminal 70, and the power consumption is changed, or the sub terminals 80 ₁ to 804 ₄ A setting process (see FIG. 8) is executed by operating the input unit 80b, and it is determined whether or not the required power stored in the required power storage units 47 and 48 has been changed (step S54).

  When the control unit 21 (CPU 22) determines that the consumable power or the required power has been changed (step S54: Yes), the process returns to step S43. On the other hand, when it is determined that the consumable power and the required power are not changed (step S54: No), the process proceeds to step S55.

  In step S55, the control unit 21 (CPU 22) determines whether or not the end of execution of the power accommodation process is instructed by an operation of the input unit 70b of the main terminal 70 (step S55). If it determines with the control part 21 (CPU22) not having instruct | indicated execution completion of an electric power interchange process (step S55: No), it will return to step S53. On the other hand, if it determines with the control part 21 (CPU22) having been instruct | indicated execution completion | finish of an electric power accommodation process (step S55: Yes), this electric power accommodation process will be complete | finished.

As described above, according to the power control system 10 according to the first embodiment of the present invention, the consumable power (electrical equipment 551 _to 554 ₇ used in all (consumption) can power upper limit), in the operation the electrical equipment ₅₅₁ to 554 ₄ of the individual area R1~R4 consuming the required power (required power), when partitioned between electrical equipment ₅₅ 5-55 ₇ shared areas C1 to C3, to ensure the required power When there is an electric facility in an individual area that cannot be used, the electric power consumed by the electric facility arranged in the common area is reduced, and the reduced amount is supplied to the electric facility in the individual area where the required power cannot be secured. As a result, in order to suppress the total power consumed by the electrical equipment within the upper limit, compared to a system that uniformly reduces the power consumed by the electrical equipment, the electrical equipment in an individual area where the required power cannot be secured. Occurrence can be reduced. Therefore, the power consumed by the electrical equipment ₅₅₁ to 554 ₇ in the building 100 on which is suppressed in the upper limit, disadvantage that may occur in electrical equipment of the individual regions (e.g., electrical equipment ₅₅₁ to 554 ₄ are operation not possible or electrical equipment 551 _to 554 ₄ of the ability to enable reduction of inconveniences) to decrease.

(Second Embodiment)
In the first embodiment described above, when there is an electrical facility in an individual area where the required power cannot be ensured, the power that can be supplied to the electrical equipment in the common area on the same floor as the electrical facility in the individual area is reduced, and The reduction is added to the power that can be supplied to the electrical equipment in the individual area where the required power on the same floor cannot be secured (steps S45, S46, S47), and if there still remains an individual area where the required power cannot be secured (step S51) : No), the power that can be supplied to the electrical equipment in all the individual areas was adjusted again (step S52).

  However, if there is still an electrical facility in an individual area where the required power cannot be ensured by reducing only the power that can be supplied to the electrical area in the common area on the same floor, the power that can be supplied to the electrical equipment in the shared area on the other floor is reduced. The power control system according to the first embodiment indicates that if the reduction amount is added to the power that can be supplied to the electrical equipment in the individual area where the required power cannot be secured yet, the electrical equipment in the individual area where the required power cannot be secured is generated. Compared with 10, it can be further reduced.

  In this case, the power accommodation process of the first embodiment shown in FIG. 9 may be changed to the power accommodation process of the second embodiment shown in FIG. The power interchange process of the second embodiment is a process in which a distribution process (step S60) is added to the power interchange process of the first embodiment.

  Other configurations are the same as those of the power control system 10 of the first embodiment. Therefore, in the power control system 10 of the second embodiment, only the parts different from the power accommodation process of the first embodiment will be described using the flowchart of the power accommodation process shown in FIG.

  When the control unit 21 (reduction supply unit 26) determines in step S51 that at least one of the first to third shortage flags 32 to 34 is on (step S51: Yes), the shared area on the other floor. The distribution process (step S60) is executed in order to reduce the power that can be supplied to the electrical equipment and add the reduction to the power that can be supplied to the electrical equipment in the individual area where the required power cannot be secured yet.

  In the distribution process (step S60), as shown in FIG. 11, the control unit 21 (reduction supply unit 26) searches for a common area where there is an electric facility of reducible power that can be reduced. It is determined whether or not there is a shortage flag that is turned off among 32-34 (step S61). When the control unit 21 (reduction supply unit 26) determines that none of the first to third shortage flags 32 to 34 has the shortage flag turned off (step S61: No), the reducible supply is possible. It is determined that there is no electric facility in the common area that is electric power, and the distribution process is terminated (the process proceeds to step S53).

  On the other hand, when the control unit 21 (reduction supply unit 26) determines that any of the first to third shortage flags 32 to 34 has the shortage flag turned off (step S61: Yes), it is turned off. It is determined whether or not the power that can be supplied to the electrical equipment in the common area existing on the floor corresponding to the shortage flag is reduced (step S62). A specific determination method is the same as that in step S46.

  When the control unit 21 (reduction supply unit 26) determines that the power that can be supplied to the electrical equipment in the shared area existing on the floor corresponding to the shortage flag that is off (step S62: Yes), the shared area Is reduced by a predetermined amount (for example, 200 W), and the reduced amount is added to the suppliable power of the electrical equipment in the individual area where the shortage relative to the required power is the largest (step S63).

  In addition, the electric equipment of the individual area where the shortage with respect to the required power is the largest means the electric equipment of the individual area where the difference between the suppliable power and the required power is the largest.

  Thereafter, the control unit 21 (insufficient identification unit 25) determines whether or not there is an electrical facility in an individual area where the required power cannot be secured (step S64). Specifically, the control unit 21 (insufficient identification unit 25) compares the current suppliable power and the required power for each electrical facility in the individual area, and the individual area where the suppliable power is less than the required power. It is determined whether there is electrical equipment (step S64).

  If the control unit 21 (insufficient identification unit 25) determines that there is an electrical facility in an individual area where the required power cannot be secured (step S64: Yes), the process returns to step S62. On the other hand, if the control unit 21 (insufficiency specifying unit 25) determines that there is no electrical facility in the individual area where the required power cannot be secured (step S64: No), the distribution process ends (the process proceeds to step S53).

  In step S74, if the emergency flag 35 is off, the control unit 21 (insufficient identification unit 25) uses the required power stored in the normal request power storage unit 47, and if the emergency flag 35 is on. The required power stored in the emergency required power storage unit 48 is used.

  In step S <b> 62, the control unit 21 (reduction supply unit 26) stores, in the shared minimum power storage unit 45, power that can be supplied to the electrical facilities in the shared area that exists on the floor corresponding to the shortage flag that is off. If it is determined that it is equal to the minimum power and the suppliable power cannot be reduced (step S72: No), the process proceeds to step S52. Thereafter, the control unit 21 (reduction supply unit 26) ends this distribution process (the process proceeds to step S53).

As described above, according to the power control system 10 according to the second embodiment of the present invention, it is possible to reduce the suppliable power to the electrical facilities in the common area existing on the same floor as the individual areas where the required power cannot be secured. Alone, if there is an electrical facility in an individual area where the required power cannot be secured, reduce the power that can be supplied to the electrical equipment in the shared area on the other floor, and the reduced power cannot be secured yet. In addition to the available power for the electrical equipment in the area. Therefore, in order to keep the total power consumed by the electrical equipment within the upper limit, there is an electrical facility in an individual area where the required power cannot be secured compared to a system that uniformly reduces the power consumed by the electrical equipment. This can be further reduced. Therefore, the power consumed by the electrical equipment 551 _to 554 ₇ in the building 100 on which is suppressed in the upper limit value, to allow a further reduction of the disadvantages that may occur in the electrical equipment of the individual regions.

(Third embodiment)
In the first embodiment described above, when there is an electrical facility in an individual area where the required power cannot be ensured, the suppliable power of the electrical facility in the shared area on the same floor as the individual area is reduced, and the reduction is reduced. In addition, the required power on the same floor is added to the power that can be supplied by the electric equipment in the individual area (steps S45, S46, S47).

Instead, if there is electrical equipment in an individual area where the required power cannot be secured, the power that can be supplied to the electrical equipment in all common areas will be reduced uniformly, regardless of which floor it is on. The reduction may be added to the power that can be supplied to the electrical equipment in each individual area where the required power cannot be secured. According to this process, it is possible to suppress the occurrence of electrical facilities in individual areas where required power cannot be secured by using the power that can be supplied to the electrical facilities in all shared areas. Therefore, even with this process, the power consumed by the electrical equipment 551 _to 554 ₇ in the building 100 on which is suppressed in the upper limit value, it is possible to reduce the inconvenience that may occur in the electrical equipment of the individual regions.

  In this case, the power accommodation process of the first embodiment shown in FIG. 9 may be changed to the power accommodation process of the third embodiment shown in FIG. Note that the power accommodation process of the third embodiment is obtained by adding the following changes to the power accommodation process of the first embodiment. That is, in the power accommodation process of the third embodiment, step S43 of the power accommodation process of the first embodiment is changed to step S81, and steps S45 to S51 are changed to steps S82 to S86.

  Other configurations are the same as those of the power control system 10 of the first embodiment. Therefore, in the power control system 10 of the third embodiment, only a portion different from the power accommodation process of the first embodiment will be described using the flowchart of the power accommodation process shown in FIG.

  If the control unit 21 (CPU 22) determines in step S42 that acceptance of power interchange has been completed (step S42: Yes), the first shortage flag 32 is set to OFF as an initial setting (step S81).

  In the third embodiment, the first shortage flag 32 is used as a flag indicating whether or not there is an electrical facility in an individual area where the required power cannot be secured in any of the individual areas R1 to R4. The first shortage flag 32 is turned on if there is even one electrical facility in the individual area where the required power cannot be secured, while the first shortage flag is present if there is no electrical facility in the individual area where the required power cannot be secured. 32 is turned off.

  If it determines with Yes by step S42, the control part 21 (insufficient specification part 25) will determine whether there exists any electrical equipment of the separate area | region which cannot ensure required electric power (step S82). Specifically, the control unit 21 (shortage specifying unit 25) compares the suppliable power calculated by the suppliable power calculation unit 24 and the required power for each electrical facility in the individual area, and the suppliable power is requested. It is determined whether there is an electric facility in an individual area that is less than electric power (step S82).
