The power system display function 5 is a function of selecting display information / non-display information according to an instruction from the display content limiting function 4 and displaying the limited display content and the grid voltage predicted value and the power flow predicted value. The interlock function 1, the special condition confirmation function 2, the system voltage prediction calculation function 3, and the display content limitation function 4 constitute a necessary and sufficient condition determination processing device 22. The necessary and sufficient condition determination processing device 22 starts its function by a signal from the operation target confirmation processing function 21. Further, the content of the operation target confirmation processing function 21 is displayed on the abnormality information display processing device 25. The display format selection processing function 6 selects a display format according to the output signal from the power system display function 5. The system diagram rearrangement function 7 is a function for examining and processing the system diagram rearrangement and operation information arrangement. The power system display function 5, the display format selection processing function 6, and the system diagram rearrangement function 7 constitute the display information conversion processing device 23. The information display processing device 24 displays the output signal from the display information conversion processing device 23.

Information on an operation to be performed in a power system operating device in which a display device, a data input device, a signal input / output device, and a processing device for processing various data, condition judgment, and programs are organically combined with these devices. However, by inputting from the data input device, the current state of the electric power system and the conditions to be considered for the operation in the processing device are processed with the information input from the data input device or the signal input / output device. An operation that has the function of displaying on the display device only the necessary and sufficient information that should be confirmed on the display device by performing processing such as calculation, judging from the information stored in the device. It is a support system. Therefore,
In the driving support system of the present embodiment, the necessary and sufficient conditions are embossed and displayed on the display device by deleting and displaying unnecessary parts for this operation from the overall system diagram for normal operation, so confirmation is required. It is easy to perform and reduces omission of confirmation, operation mistake, etc.

From the entire electric power system diagram displayed on the data display device 12 shown in FIG. 1, when the information of the device to be operated is inputted from the data input device 11, the information processing device 13 becomes a signal input / output device. From the information input from 14 and the information stored in the information processing device 13, the necessary and sufficient conditions to be confirmed for the operation of the device are determined, calculation processing, etc. are performed, and unnecessary according to the overall system diagram of the data display device 12. Delete the part and display only the necessary and sufficient information.

The contents to be judged and calculated in the information processing device 13 and the contents displayed on the data display device 12 are, for example, (1) whether the device to be operated is currently the operation target from this device. Is determined from the operation mode information, and if it is not the operation target, a message to that effect and the reason thereof are displayed on the data display device 12.

(2) The presence / absence of the device interlocked with the device to be operated is determined from the device status information and the interlock information, and if there is, it is displayed on the data display device 12. The interlock condition is displayed near the symbol of the device in the overall system diagram.

(3) By operating the device to be operated, the presence / absence of the device to be interlocked is determined from the device status information and the interlocking operation information, and if there is, it is displayed on the data display device 12. The operation display is displayed near the symbol of the device in the overall system diagram.

(4) The state after operating the device to be operated is simulated, the power flow of the entire system at that time is calculated, and the flow of electric power / reactive power, voltage, etc. have changed from the current state. In this case, the calculation result is displayed in the entire system diagram of the data display device 12. This simulation also considers interlock devices and interlocking devices.

(5) Check the special condition of the device to be operated, and if there is, display the condition near the operating device.

Etc.

Other than these contents are deleted from the entire system diagram displayed on the data display device 12. In this way, by displaying only the necessary and sufficient information, the operator can see only the items that should be checked, so it is possible to reduce omission of confirmation, and the system state after operation is also highlighted. Therefore, operation mistakes are reduced, which is useful for raising operational awareness and knowledge. Further, not only the judgment result or the calculation result in the information processing device 13 is displayed on the data display device 12, but also the judgment result or the calculation result is displayed as a guidance for the operation so that the operation can be performed. It becomes possible to give flexibility to.

As another embodiment, not only the judgment result and the calculation result are displayed in the whole system diagram, but also the judgment result and the calculation result are confirmed and operated by the data input device 12, By displaying the operated items in different colors on the data display device, it is possible to further reduce omission of confirmation. Further, when the entire system diagram becomes large and the related systems are not displayed on the data display device 12 at a time, it is possible to cope by displaying the related system in a window.
