Field of the Invention The present invention relates to a power system monitoring and control system for monitoring and controlling a power system based on information input from equipment constituting a power system via communication equipment, and a storage medium for storing a program for the system. .

[0002]

2. Description of the Related Art In general, electric power is generated at a power plant distant from a demand area, and is supplied to consumers via long transmission lines and power transmission facilities and distribution facilities such as substations. Each power company must control power generation and transmission throughout the day in response to ever-changing power demand.

[0003] Today, power system monitoring and control of a centralized control station system and the like to monitor a complicated and large-scale power system in close contact with social life and to stably supply high-quality power while balancing supply and demand. The system has become essential.

This power system monitoring and control system monitors and controls a wide range of a power system. Binary information such as switching on / off of a switch and output of a generator from equipment constituting the power system via communication equipment. Numerical information such as the power flow of the transmission line is input, and the binary information and the numerical information are notified to the operator by a single-line diagram of the power system drawn on the system monitoring panel.

[0005] This system monitoring panel is formed of large panels so that a plurality of operators can constantly monitor the state of the power system at a control station. In addition, the system monitoring panel is composed of transmission lines, buses, switches, transformers, and the like. A single line connection diagram is constructed by combining square symbols and unmarked display blocks depicting the symbols of each equipment such as switches and their names in correspondence with the power system diagram like a mosaic, and "On" of the switch with red and blue light emitters provided near,
Displays binary information such as "OFF" and the generator, bus,
A digital display arranged near a facility symbol such as a transmission line displays numerical information such as generator output, bus voltage or power flow.

FIG. 6 shows a system configuration diagram for displaying a system monitoring panel in a conventional power system monitoring and control system. This power system monitoring and control system is composed of a telecontrol device (hereinafter referred to as a “telecon”) 2, a system monitoring panel display device 3, a system monitoring panel 4, and a system monitoring computer system 5, and the telecon 2 and the system monitoring Panel display 3
And a system monitoring computer system 5, and a system monitoring panel display device 3 and a system monitoring panel 4 are connected to each other.

[0007] The system information of the power system 1 is input to the teleconverter 2, where system data (binary information and numerical information) is created and output to the system monitoring panel display device 3 and the system monitoring computer system 5. This system monitoring panel display device 3
