Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power system monitoring and controlling apparatus, and more particularly to a power system monitoring and controlling apparatus for outputting a change in the status of a power system to a system monitoring board.

[0002]

2. Description of the Related Art Generally, for control of a switch of a power system, a part of the power system information including the switch of the power system is displayed on a display device, for example, a CRT device, and the displayed switch symbol of the power system is selected. The operation information to the electronic calculator,
This is done by transmitting it to the switch of the local power system via the remote monitoring and control device. On the other hand, the system monitoring panel displays the states of the switches of all the power systems monitored by the power system monitoring and control device.

FIG. 3 is a block diagram of a conventional power system monitoring and controlling apparatus 1. The power system state is taken into the remote monitoring control device controller 11 via the remote monitoring control device 2,
The signal capturing / storing / state detecting means 111 notifies the system monitoring board controller 12 and the man-machine interface device controller 13. The man-machine interface device controller 13 outputs this power system state change information to the CRT device 3 by the man-machine output / control means 113. On the other hand, the system monitoring board controller 12 outputs the same change information of the power system state to the system monitoring board 4 by the system monitoring board output means 114.

The control of the switch of the power system is
The control information of the selection operation from the CRT device 3 is fetched by the man-machine output / control means 113, notified to the remote control device controller 11, and the control means 112 of the switch of the electric power system,
It is judged whether the operation of the switch of the electric power system is allowed, and if it is allowed, the switch of the electric power system is controlled (turned on and off) via the remote monitoring and control device 2, and if not allowed, the man-machine output / control is performed. The means 113 is notified accordingly.

[0005]

In the configuration of the conventional power system supervisory control device described above, control of the switch of the power system is possible only from the CRT device. On the other hand, the system that can be displayed on the CRT device is a part of the system due to the restrictions of the screen of the CRT device. Therefore, when performing an operation in consideration of the entire power system, while displaying several subdivided systems on the CRT device at any time. There is an inconvenience that it is necessary to perform the operation while alternately comparing or comparing all power system information of the system monitoring panel.

In recent years, due to the expansion of the scale of the electric power system and the centralized control of the electric power system monitor and control device, the range of the electric power system under its control has been expanded, and the burden on the operator has become heavier. In such a situation, even a trained operator would find it extremely difficult to operate the switch of the power system in consideration of the entire power system, and in some cases even erroneous control could occur.

Further, when the electronic computer is stopped for reasons such as hardware maintenance, the conventional power system monitoring and controlling apparatus described above can only monitor the switch of the power system by the system monitoring board, and The operation of the switch has to be done directly at the site where the switch of the electric power system is installed by telephone contact or the like, which requires labor such as arrangement of personnel.

According to the present invention, the power system equipment displayed on the system monitoring panel can be wirelessly controlled from a remote place without increasing the burden on the operator, so that the operator is aware of the entire system. It is an object of the present invention to provide a power system supervisory control device capable of controlling a switch of a power system even when the electronic computer is stopped for some reason.

[0009]

In order to achieve the above object, the present invention corresponds to a remote control device, a receiver for inputting a signal from the remote control device in a system monitoring panel, and a selection operation from the remote control device. In addition to providing a message display, add system monitoring panel control means to control signals from remote control devices from the system monitoring panel to the power system monitoring device and the switch of the local power system via the remote monitoring control device. It was done.

[0010]

By providing the remote control device for selectively operating the switch symbol of the power system displayed on the system monitoring board, the switch of the power system can be controlled from the remote control device.

[0011]

Subsequently, S22 is a process of determining whether the above-described selection operation information has appropriate contents. S23 inquires from FIG. 1 and the control means 112 of the switch of the electric power system whether the operation of the switch of the electric power system is permitted based on the contents of the above selection operation information. This is a process of notifying the control means 112 of the switch of the electric power system of the selection / operation of the switch of the electric power system.
