Problems solved by technology

This method needs to establish a detailed and accurate mathematical model. At the same time, because a large number of power supply systems are required in the simulation process, it takes a lot of time. Therefore, although it can well meet the requirements of simulation accuracy, it cannot be very good. Meet real-time requirements

Embodiment Construction

[0027] Below in conjunction with embodiment the present invention is described in further detail:

[0028] Such as figure 1 As shown, the relay protection simulation training system in the subway OCC power dispatching system includes a fault processing terminal for trainees’ operation, a fault setting terminal for trainers’ operation, a microprocessor for receiving and processing trainees’ and trainers’ operation data, a storage There is a memory for the simulation diagram program of the subway OCC power system and a database server that supports microprocessor operations. The fault processing terminal, the fault setting terminal, the memory and the database server are all connected to the microprocessor.

[0029] Both the fault processing end and the fault setting end are common PCs.

[0030] The data in the database server includes a fault table, a protection equipment table, a protection type table, a protection relation table and an input-output relation table.

Abstract

The invention discloses a simulation training system of relay protection in subway OCC power dispatching and a method thereof. The system comprises: a fault processing terminal, which is used for operation by a student; a fault arranging terminal, which is used for operation by a teacher; a microprocessor, which is used for receiving and processing operation data of the student and the teacher; amemory, which is used for storing a subway OCC power system simulated diagram program; and a database server, which is used for storing data supporting the operation of the microprocessor. Besides, the fault processing terminal, the fault arranging terminal, the memory and the database server are connected with the microprocessor. According to the invention, beneficial effects are as follows: various actual equipment faults can be accurately simulated as well as situations of failed operation and misoperation of a protection and breaker can also be simulated; a mixing simulation method is employed to establish a model; that is, if it is allowed to use a logic determination method for protection, the logic determination method is used whenever possible; if it is not allowed to use the logic determination method, a fixed value determination method is used; therefore, a motion rule of relay protection in reality can be accurately simulated; and requirements on accuracy and a real-time property can be met simultaneously.
