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 control apparatus for monitoring and controlling power system equipment, and a power system monitoring and control training apparatus for simulating training of power system equipment.

[0002]

2. Description of the Related Art The scale of a power system is becoming more complicated and larger year by year due to an increase in power demand, and accordingly, power system equipment constituting the power system is also expanding. In order to smoothly and efficiently supply high-quality power to consumers, operators of each power company perform monitoring and control of these power system facilities using a power system monitoring and control device. In recent years, the power system range that must be monitored and controlled by one power system monitoring and control device has been widened due to the enlargement of the power system. For this reason, the responsibilities of power systems that have been monitored and controlled by a single power system monitoring and control device in the past have been reviewed, and independent power system monitoring and control devices have been installed in the divided power systems. ing.

[0003] On the other hand, the role of the power system monitoring and control device is very important in operating such a power system. In order to enable continuous operation of the power system monitoring and control device, consider the following preventive measures against loss of function of the power system monitoring and control device due to failure of the power system monitoring and control device or transmission system. It is designed. (1) The main functions of the device are multiplexed to improve reliability. (2) The main transmission line such as the information transmission line and the transmission line of the important electric power plant remote control signal is formed as multiple routes as possible to improve the reliability of the transmission system. (3) Multiplexing of important power substations such as a main system substation and a remote monitoring control device of a power system monitoring control device.

[0004]

However, even if the above-mentioned preventive measures are taken, if the power system monitoring and control device is damaged due to a fire or a natural disaster and its function is lost, the operator is required to generate and transform power. You have to go to the office and perform the monitoring and control directly on site.

Hereinafter, a conventional power system monitoring and control device will be described with reference to FIG. For a large-scale power system, a plurality of power system monitoring and control devices 1 are provided, and each of the power system monitoring and control devices 1 performs monitoring and control over a predetermined range obtained by dividing the power system. .

The power system information of the power system 2A to be monitored and controlled by the power system monitoring and control device 1A is collected by the remote monitoring and control device 5A and transmitted to the computer 4A. That is, the remote monitoring control device 5A is connected to the computer 4A via the LAN 3A, and the power system information of the power system 2A is input to the computer 4A. Computer 4A
Has a facility database 6A that stores facility information of the power system 2A, and performs processing of the power system information of the power system 2A based on the facility database 6A.

The operator operates a man-machine interface device 7A connected to the computer 4A via the LAN 3A.
Is used to monitor and control the power system 2A to be monitored and controlled based on the power system information. The power system monitoring and control device 1A composed of these devices performs monitoring and control of only the power system 2A, and has an independent configuration as a device.

On the other hand, the same applies to the other power system monitoring and control device 1B. The power system information of the power system 2B to be monitored and controlled by the power system monitoring and
The data is input to the computer 4B from the remote monitoring control device 5B connected to the computer 4B via B. The electronic computer 4B has a facility database 6B that stores facility information of the power system 2B, and performs processing of the power system information of the power system 2B based on the facility database 6B. The operator
Using the man-machine interface device 7B connected to the computer 4B via the LAN 3B, the monitoring and control of the power system 2B to be monitored and controlled is performed based on the power system information. The power system monitoring and control device 1B composed of these devices performs monitoring and control of only the power system 2B, and also has a configuration independent of the power system monitoring and control device 1A. Note that the same applies to the power system monitoring and control apparatus 1N, and therefore the description is omitted.

In such a power system monitoring and control device 1,
When the function of each power system monitoring and control device 1 is lost, monitoring and control of the target power system 2 becomes impossible. For this reason, it is necessary to quickly restore the power system monitoring and control device 1, but if this is not possible, the operator must go to each power substation and perform monitoring and control directly on site. If operators encounter serious accidents and their accompanying spills in the power system before they arrive at each substation, they will not be able to monitor or recover from these accidents at all, and the spills The range was further expanded, and there was a possibility that the power supply would be greatly hindered.

[0010] As described above, in the conventional power system monitoring and control device 1, when the function of the power system monitoring and control device 1 is lost, the operator directly monitors and controls on site, and the power system monitoring and control is performed. The continuous operation by the control device 1 cannot be performed. In addition, monitoring and control are not possible at all until monitoring and control are started directly on site,
There is a problem that a recovery operation cannot be performed at all during the power system accident that occurred during this time.

In order to acquire knowledge of a recovery operation method for an accident requiring a recovery operation over a plurality of power systems, an independent power system monitoring and control device 1 is installed in each power system 2. Therefore, there is a problem that it is not possible to carry out practical training in accordance with the actual situation, such as communicating with each other and performing a recovery operation.

An object of the present invention is to enable smooth monitoring and control to be continued even when the function of the power system monitoring and control device under its jurisdiction is lost, and to provide a recovery operation for an accident that requires a mutually coordinated recovery operation. The purpose is to obtain a power system monitoring and control training device that can perform training.
