Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power system simulator for simulating the state and control operation of components of a power system using an electronic computer.

[0002]

2. Description of the Related Art A power system monitoring and control device plays a major role in monitoring and controlling a power system. The operation of this power system monitoring and control device is quite complex and requires a great deal of experience before the operator gets used to it. However, it is extremely rare that an accident or the like occurs in the actual power system and the power system falls into an abnormal state, and the user cannot get used to the operation. Up to now, various changes from an actual accident to an abnormal state have been stored in chronological order, and a training scenario with information on failure type, failure duration, failure equipment, etc. has been created, and based on this, The simulation of the system and the training of the operators were carried out by reproducing the change of
Mannering has been an obstacle and the desired training effect has not been obtained.

FIG. 13 shows an example of a conventional power system simulation device. An accident change from the power system 101 is input to the power system monitoring and control unit 103 via the information transmission device 102. From the power system monitoring control means 103,
By receiving the notification of the status change, the pre-accident system preservation means 104 is provided.
Saves the power system before the accident stored immediately before the accident as the initial system of the training scenario in the initial system state data 105 together with the storage time when the accident occurs. In addition, the actual accident state storage unit 106 stores the accident state change in the power system monitoring and control device 10.
Given from 3. This saves the state change information together with a code for specifying the facility (hereinafter, referred to as a facility code) and a state change time in the facility.

[0004] Next, the training scenario editing means 107 sets the pre-accident system saved by the actual accident condition saving means 105 as the initial system of the training scenario, and edits the situation change after the time when the accident system was saved as the training scenario. I do. The training scenario storage means 108 stores the training scenario edited by the training scenario editing means 107. Power system simulation means 109
Then, simulation of the electric power system is performed based on the training scenario, and the operator 117 can simulate the electric power system via the electric power system monitoring control means 103 and the man-machine interface means 116. Reference numeral 115 in the figure indicates an electronic computer.

[0005]

As described above, when creating a training scenario based on an actual accident situation change, a training scenario based on the actual accident situation change is created in the very system where the actual accident situation occurred. However, training scenarios that can be created because they depend on actual accident state change data are limited to the power system in which the actual accident occurred, and training scenarios for other power systems cannot be created. In some cases, training using the same training scenario in the same system alone is not useful for an actual accident requiring a measure corresponding to an opportunity, and there is a need for a method of creating a more desirable training scenario that enhances the training effect.

On the other hand, manually creating a training scenario that simulates a failure situation occurring in a power system requires a lot of trouble and is not economical.

[0007] In addition, the actual accident condition information serving as the original data for creating the training scenario can be used only in the own computer system, and other power systems including the adjacent power system, Even if the computer under monitoring and control is a serious accident occurring in a different similar system, a training scenario cannot be created from the actual accident information. Therefore, in order to simulate such an accident, it is necessary to manually create a training scenario, which is wasteful.

[0008] Similarly, there is no means for converting a real fault into a training scenario for a serious fault that has occurred in a power system under the control of another power supplier, and a case study is required for operators. In addition, a training scenario for simulating the failure must be created by the trainee with much effort.
