A control signal for controlling the state of the electrical equipment installed in the power system (for example, outputting a closing command to the B circuit breaker at the A electric power station) is output to the electrical equipment to be controlled. In addition, when there is a state change (hereinafter referred to as a state change) in an electrical facility installed in the power system (such as when a circuit breaker is opened at the time of an accident), a monitoring signal including information on this state change is provided. It is received via the transmission line 2.

  The power system monitoring control system 1 includes an operation unit 3, a monitoring control unit 4, and a display unit 5. When controlling the state of the electrical equipment, the user operates the operation unit 3, the operation content is transmitted to the monitoring control unit 4, and the monitoring control unit 4 transmits a control signal corresponding to the operation content to the electrical equipment. . When monitoring the state of the power system, if there is a change in the state of the electrical equipment installed in the power system, the monitoring control unit 4 receives a monitoring signal including information on this change, and the status is received from the received monitoring signal. The change information is extracted and displayed on the display unit 5.

  Of the cases where the state of the electrical equipment installed in the power system is controlled, in the case of accident recovery work, system switching work, etc., the speed of work and the accuracy of operation procedures are required. Conventionally, the situation of power system accident recovery work and system switching work has been ascertained by experienced power system monitoring and control system users based on their experience, confirming single-line diagrams of power systems, power system tidal current diagrams, etc. ing.

(First embodiment)
A first embodiment of a power system monitoring control system according to the present invention will be described with reference to FIG. FIG. 1 is a diagram showing the configuration of this embodiment.

The power system monitoring control system 1 of this embodiment is
The power system monitoring control system 1 includes an operation unit 3, a monitoring control unit 4, a display unit 5, a user specifying unit 6, a user data storage unit 7, an operation pattern creation unit 8, an operation pattern data storage unit 9, and an operation pattern comparison. Part 10 and an improvement pattern creation part 11. Since the operation unit 3, the monitoring control unit 4, and the display unit 5 have the same configuration as that of the conventional power system monitoring control system, description thereof is omitted.

  The user specifying unit 6 compares the input information input to the operation unit 3 by the user with the user specifying information stored in the user data storage unit 7 to specify the user. Furthermore, the user information indicating the specified user information is output to the operation pattern creation unit 8 and the operation pattern comparison unit 10.

  Here, the input information input to the operation unit 3 by the user includes input of an ID number given to each user, input of an IC chip, biometric authentication of the user (fingerprint reading, retina authentication, etc.) However, any information that can distinguish each user may be used. Further, the user specifying information stored in the user data storage unit 7 is information stored in advance corresponding to the input information described above. That is, the user specifying information indicates information that is set and stored in advance in order to collate with the input information input by the user.

  The operation pattern creation unit 8 operates the information indicating the identified user operation pattern based on the user information output from the user identification unit 6 and the operation procedure for the user to operate the operation unit 3. The data is stored in the pattern data storage unit 9. Here, FIG. 2 shows an example of information indicating the specified user operation pattern.

  FIG. 2 shows “via screen” indicating the screen through which the users A, B, and C display the target screen 5 from the initial screen 1, “transition frequency” indicating the number of times the screen has been changed, and from the initial screen 1. A “display time” indicating the time required to display the target screen 5 is written. For example, from the initial screen 1 to the display of the target screen 5, the user A goes through the screens 2 and 3, and the “transition number” of the screen is 3 times and the “display time” is 10 seconds. Show.

  The operation pattern comparison unit 10 compares each user's operation pattern created by the operation pattern creation unit 8 and stored in the operation pattern data storage unit 9, and the user operation pattern identified by the user identification unit 6. Is determined to be less efficient than other users, an improvement signal is output to the improvement pattern creation unit 11.

  Upon receiving the improvement signal from the operation pattern comparison unit 10, the improvement pattern creation unit 11 extracts the most efficient pattern from the operation patterns of each user stored in the operation pattern data storage unit 9, and displays the display unit. 5 is displayed.

  Here, when the operation pattern comparison unit 10 determines whether or not each user's operation pattern is efficient, or the improvement pattern creation unit 11 extracts the most efficient pattern from each user's operation pattern. The determination criteria to be set can be freely set by an administrator or manufacturer of the power system monitoring and control system. For example, it may be determined whether or not the “number of transitions” or “display time” shown in FIG. 2 is the best.

  Next, the operation of the power system monitoring control system of this embodiment will be described with reference to FIG. FIG. 3 shows a flowchart of the power system monitoring control system of the present embodiment.

  The user specifying step S1 is a step of determining whether or not the user has been specified by the user specifying unit 6, and if it is determined by the user specifying unit 6 that the user has not been specified, the flow is performed. The monitoring and control operation similar to that of the conventional power system monitoring and control system is performed. When it is determined that the user is specified by the user specifying unit 6, the process proceeds to operation pattern storage step S2.

  The operation pattern storage step S2 is performed by the operation pattern creation unit 8 based on the user information output from the user specifying unit 6 and the operation pattern in which the user operates the operation unit 3. The figure shows a step of storing information indicating an operation pattern in the operation pattern data storage unit 9.

  The operation pattern comparison step S3 compares the operation patterns of each user stored in the operation pattern data storage unit 9 in the operation pattern storage step S2, and the user operation pattern specified by the user specifying unit 6 It is a step which judges whether it is more efficient than a user. If it is determined that the identified user's operation pattern is more efficient than other users, the flow is terminated. When it is determined that the identified user operation pattern is not more efficient than other users, the process proceeds to an improvement plan display step S4.

  In the improvement plan display step S4, when the improvement pattern creation unit 11 receives the improvement signal from the operation pattern comparison unit 10, the most efficient operation pattern among the user's operation patterns stored in the operation pattern data storage unit 9 is obtained. In this step, a pattern is extracted and displayed on the display unit 5. After the most efficient pattern is displayed on the display unit 5, the flow ends.

  According to the present embodiment, since the most efficient operation pattern (screen transition information) can be displayed among each user, it is possible to grasp the power system even if the user is not a skilled power system monitoring control system user. It is possible to provide a power system monitoring and control system that does not waste time and does not lead to work delays.
