Referring to fig. 1, in a first aspect, an embodiment of the present application provides a base station voltage boosting system, including a voltage boosting module, where the voltage boosting module is electrically connected to an external power grid and a base station, respectively;

Specifically, the boosting module can be electrically connected with an external power grid and the base station through a power supply line, the voltage output by the external power grid is boosted through the boosting module to obtain a first target input voltage, and the first target input voltage is input into the base station to provide electric energy for the base station. The boost module may be an autotransformer. The first preset threshold is a voltage value determined according to specific conditions. It is understood that when the first target input voltage is input to the base station through the power supply line, there is a line loss, and the voltage actually input to the base station is smaller than the first target input voltage.
In the prior art, power is increased by increasing current to realize capacity expansion of power capacity of a base station.

In a second aspect, referring to fig. 3, an embodiment of the present application provides a base station boosting method applied to the base station boosting system according to the first aspect, including:
It should be understood that, under the condition that the base station is not expanded, the impedance Z of a power supply line electrically connecting the boosting module with the external power grid and the base station respectively is basically unchanged, and the base station with excessively low input voltage is subjected to intelligent boosting transformation, so that the working stability of the base station equipment can be improved.
Suppose the voltage output by the external network of the base station is V0，V0The nominal value of (A) is 220V, and only the input voltage of the base station end is less than or equal to V1The base station carries out intelligent boosting transformation.
Before boosting, the initial input voltage at the base station end is V1Time, line voltage drop V2＝V0-V1Power supply efficiency η of grid sideBase station＝V1/V0Let the base station end energy consumption (also called power consumption) be PLoad(s)If the power consumption P of the external power grid end is equal to V0PLoad(s)/V1。
Suppose we input the initial input voltage of the base station end, i.e. the input voltage value V of the base station before boosting1Intelligent boost to V3To keep the minimum goal of external grid-side energy consumption unchanged, at least the following conditions must be met:
line impedance: z ═ V0-V1)/(PLoad(s)/V1)＝(V0-V1)*V1/PLoad(s)；
Before boosting: pLoad(s)/(V1/V0)＝PLine+PLoad(s)I.e. PLoad(s)*V0/V1＝Z*(PLoad(s)/V1)2+PLoad(s)；
After boosting: z (P)Load(s)/V1)2+PLoad(s)≥(Z*(PLoad(s)/V3)2+PLoad(s))/η。
Known as V0Has a nominal value of 220V, let V0220V, and is obtained by solving the above equation set
After the intelligent boosting, the overall power supply efficiency of the base station is
Wherein, V3For the input voltage of the base station after boosting, i.e. the base station terminalThe actual boost value.
After the intelligent voltage boosting, the first target input voltage value output by the voltage boosting end is
The value range of η may be 0.9 to 1, taking an intelligent boosting device with efficiency η of 0.95 as an example, and for base stations with different output voltages, the boosting transformation results are shown in table 1:
TABLE 1
As can be seen from table 1, the first preset threshold may be 190V, and the base station with the initial input voltage of the base station terminal below 190V uses 250V as the target boost value of the base station terminal to perform intelligent boost reconstruction, so that the working stability of the base station equipment is improved, and the overall power supply efficiency of the base station can also be improved.
The base station end target boosted voltage value is a voltage value input into the base station end in plan, but the target can not be achieved in practice.
The above discusses that under the condition that the base station is not expanded, the base station with excessively low input voltage is subjected to intelligent boosting transformation, so that the working stability of the base station equipment can be improved, and the overall power supply efficiency of the base station can be improved. The following describes a case where the capacity of the base station is expanded by performing intelligent boosting modification on the base station to reduce the cost. Optionally, a ratio N of a voltage value of the first target input voltage to an output voltage output by the external power grid1Satisfies the following conditions: n is a radical of1≤(220η-V1)/(220-V1)*(V3/V1)2Wherein V is1The value of eta is 0.9-1V before boosting3The base station input voltage is the boosted base station input voltage.
When the capacity of the base station is expanded, namely the power capacity of the base station is increased, the intelligent boosting transformation is carried out on the base station with excessively low input voltage, and a power supply line for connecting an external power grid and the base station is not transformed.
The line impedance Z is unchanged, as can be seen without modifying the power supply line. Assuming base station load capacity to be N of initial load1The efficiency of intelligent boosting is eta, and the input voltage of the base station end is from V1Boosted to a voltage value V3The power supply line can bear the current after capacity expansion.
Before load capacity increase, the power supply efficiency eta base station at the power grid end is V1/V0，V0Is 220V. The scheme provided by the present application is illustrated by taking an example in which the intelligent step-up/step-down single-ended efficiency η is about 0.95.
Load capacity increase to N of initial load at base station end1At double time, the current on the supply line will increase to the initial load current value I1Of (V)1/V3)*N1Multiple, line drop V2Will also increase to (V)0-V1)*(V1/V3)*N1。
The output voltage value V after boosting is more than or equal to V3+(V0-V1)*(V1/V3)*N1(ii) a If the power supply efficiency before the base station load expansion is not reduced, at least V must be satisfied1/V0≤η*V3/(V2+V3) Substituted into V2＝(V0-V1)*(V1/V3)*N1Is provided with V0Calculated as 220V nominal value
When the base station end intelligent boost target value V3When the base station load capacity is determined, if the integral power supply efficiency of the base station is kept unchanged, the multiple N of the base station load capacity increase1≤(220η-V1)/(220-V1)*(V3/V1)2At V3Under the implementation condition of less than or equal to 250V, the whole power supply efficiency of the base station needs to be kept unchangedThere is little room for compatibilization.
If the power supply efficiency of the base station is not maintained in the capacity increasing process of the base station, setting V0At 220V nominal, we determine the boost value at the base station (e.g., V)3250V), the first target input voltage V after single-ended intelligent boosting is 220V1N1/V3-V1 2N1/V3+V3At this time, the overall power supply efficiency η of the base station is equal to V3 2η/(220V1N1-V1 2N1+V3 2)。
Taking a certain base station as an example, the calculation results are shown in table 2.
TABLE 2
As can be seen from table 2, in the process of expanding the capacity of the base station, when the power supply efficiency of the base station is not considered, as long as the power supply line meets the current requirement, single-ended intelligent boosting transformation can be implemented, the higher the output voltage V of the boosting end is, the smaller the current on the power supply line is, the smaller the line loss is, and the problem of higher cost caused by expanding and transforming the capacity of the base station in a mode of replacing a power supply line cable can be avoided.
Optionally, the method further includes:
under the condition that the first target input voltage is larger than a second preset threshold value, carrying out voltage reduction processing on the first target input voltage to obtain a second target input voltage;
providing the second target input voltage to the base station.
Specifically, referring to FIG. 2, when the supply line cannot withstand I2＝I1*(V1/V3)*N1When the current value is larger, the voltage can be increased firstly and then reduced.
Optionally, a ratio N of the second target input voltage to the first target input voltage2Satisfies the following conditions:
wherein N is1Is the ratio of the voltage value of the first target input voltage to the output voltage output by the external network, V1The value range of eta is 0.9 to 1 for the input voltage value of the base station before boosting.
After base station load capacity increase and two-stage up/down conversion, introducing the current of a power supply line to become the previous N2Times, set V0Nominal value of 220V, at which the line loss is increased by N before2 2The following relationship holds:
I2＝N2*I＝N2Pload(s)/V1；
PLineIncrease N2 2Multiple, i.e. PLine＝N2 2*(220/V1-1)PLoad(s)；
V*I2＝N1PLoad(s)/η+PLineNamely: v N2PLoad(s)/V1＝N1PLoad(s)/η+N2 2*(220/V1-1)PLoad(s)
After calculation, the first target input voltage value V output by the boosting end is 220N2-V1N2+N1V1/(N2*η)；
At this time, the overall power supply efficiency η of the base stationBase station＝η2N1V1/(N1V1+N2 2*220η-N2 2*ηV1)
If the overall power supply efficiency of the base station remains unchanged after the base station load capacity increase and the two-stage step-up/step-down conversion, the following relationship is required to be satisfied: v1/220≤η2N1V1/(N1V1+N2 2*220η-N2 2*ηV1)，
Thus:
external network lead-in line current increase multiple
In summary, in the case that both the front and rear two stages of up/down conversion efficiencies are η, the higher the first target input voltage value V output by the boost terminal is, the smaller the current on the power supply line is, and the smaller the line loss is, but after the two stages of up/down conversion, the total power supply efficiency η base station of the base station is less than η 2; if the current of the power supply line is kept unchanged, the higher the initial voltage of the base station end is, the higher the output voltage of the boosting end is, and although the overall power supply efficiency of the base station is in a rising trend, the larger the reduction amplitude is.
Optionally, the method further includes:
acquiring a voltage value of the input end of the base station;
and sending the voltage value to the boosting module.
Specifically, the voltage value of the input end of the base station can be monitored in real time through the installation detection module, the voltage value is sent to the boosting module, and under the condition that the detected voltage value is smaller than a first preset threshold value, the boosting processing can be performed on the input voltage value through a control part arranged in the boosting module, so that first target input voltage is obtained, and intelligent boosting is achieved.
Optionally, the method further includes:
acquiring parameters of a power transmission line between the boosting module and the base station;
and sending the parameters to the boosting module.
Specifically, the detection module may also monitor parameters of the power transmission line between the voltage boosting module and the base station in real time, such as the temperature of the power transmission line connecting the voltage boosting module and the base station, the power consumption of the base station, and the like, so as to implement safety monitoring or electricity charge auditing. For example, whether the abnormal condition of short circuit exists in the line can be judged through the actually measured temperature of the power transmission line connecting the boosting module and the base station, and the abnormal condition is processed in time, so that the fire caused by the short circuit of the line is avoided. The detection module may further include a communication component for sending the detected parameters to the monitoring room, for example, the detection module sends the power consumption of the base station to the monitoring room through the communication component, so as to implement remote meter reading and electricity fee auditing.
Further, the method further comprises:
and sending alarm information under the condition that the voltage value is smaller than a first preset threshold value.
Specifically, alarm module includes singlechip, bee calling organ or LED lamp, detecting system sends the parameter that detects to the singlechip, and the singlechip will the parameter is compared with the preset parameter value, and when the parameter value that detects exceeded the preset scope, the singlechip sent low potential signal, triggered bee calling organ and sent the chimes of doom or triggered the alarm lamp and glimmer.
By arranging the alarm system, when the detected parameter value exceeds the preset range, for example, the voltage value of the input end of the base station is smaller than a first preset threshold value, the alarm system sends alarm information, for example, sends an alarm sound or the alarm lamp flickers, so that related personnel can pay attention to the alarm system, and the countermeasure can be taken quickly, so that the serious consequence caused by untimely countermeasure can be avoided.
