DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system for automatically disconnecting a power failure section due to an accident in a high-voltage power distribution system and automatically processing load interchange to a normal power failure section. The present invention relates to a power distribution system monitoring device for notifying an operator of a state to be performed.

[0002]

2. Description of the Related Art Conventionally, when an accident occurs in a power distribution system,
When the accident section where the accident occurred in the distribution line is determined, it is registered in the computer at that time as the accident subject (each distribution line is treated as one subject). Subsequently, the computer charges the healthy sections on the power supply side and the load side (the healthy section is a section in which a power failure occurs due to an accident other than the own section) by the automatic interchange processing. After the restoration work of the accident section is completed, the power transmission operation to the accident section is performed according to the operator's instruction, and after all the distribution lines have been transmitted, the switchback operation for making the distribution lines into the standard system is performed. As described above, each distribution line transitions to various processing states in the processing process. The conventional method of notifying the operator of this series of changes in processing status is to display the `` accident power failure subject list '' screen that displays a list of the currently occurring accident subjects, their occurrence times, the number of power outages, etc. On the screen, the processing status of the entire subject has been changed by performing color change during operation execution, operation completion, and unfinished operation.

[0003] Also, on the "operation procedure in case of accident" screen showing the operation procedure of the feeder breaker or the switchgear for accident handling for each subject, during the calculation of the operation procedure, "procedure calculation"
When manually creating a procedure, execute the procedure "Waiting for procedure input" when waiting for the operator to enter the procedure, or "Checking editing" when checking whether the created procedure is consistent. "Waiting for procedure confirmation" when checking for inconsistencies in the previously created operation procedure, and "Waiting for button press" when waiting for the button to instruct execution of the operation procedure to be pressed. The message was displayed as follows. However, with such a message expression, it is difficult to understand the processing state of the computer unless one is an expert.

[0004]

If the display state of the processing state of the computer is not updated during the operation of the computer, what processing state the computer is currently in, and whether or not the computer is actually performing processing. The operator is anxious. In addition, stable power supply has been established today, the probability of occurrence of an accident is low, and there is little opportunity to experience operation during an accident. Therefore, when a rare accident occurs, the operator may be confused by the phenomenon and may have to call a skilled person to operate the computer. The present invention has been made to solve the above problem, and provides a display unit that displays a processing state for each accident subject, a state transition diagram, and a guidance message regarding a more detailed processing state in each transition state. It is another object of the present invention to provide a distribution system monitoring device that can be dealt with safely without being confused if an unskilled person operates according to a message provided on a display unit in the event of a distribution system accident.

[0005]

In order to achieve the above-mentioned object, a display unit for displaying a message for guiding an operator with a diagram showing a transition of a processing state with respect to a processing state of an accident subject selected by the operator, Means for recognizing a state change;
A means for updating the transition diagram and the message to a display corresponding thereto is provided. [Operation] After the accident, the accident subject is registered, and in the process of the computer performing the accident recovery processing, when the processing state changes, when the change in the processing state is recognized by the state change recognition means, the display updating means. Updates the display on the display unit.
