The Design For Rail Transit Substation Simulation Training System

Rail transit has been at an irreplaceable position in the development ofthe cities. In order to ensure long-term stable operation of the rail transit, it isnecessary to provide reliable power supply for it. As we can see, most of thepower outages that happened in recent years, are due to substation operationerrors, so the training for substation operators is particularly important. Butdue to the particularity of the substation, it is not possible for the operators toconduct on-site training. This rail transit substation simulation training systemwas built to solve this problem.The main research object of this paper is the110KV/35KV mainsubstation of Tiyu West Station on the rail transit line2. This is a distributedsystem made of three-tier client/server structure. According to therequirements of substation training, we divided the system into severalfunction modules, and designed its function training points. Through thestudy and research of the knowledge of the power system, we introduced theconcept of operation logic function in order to build the system"fault-proof" functional model, and determined the power flow calculation and typical devices’ mathematical model. Besides, we designed differentworkflow and software interfaces for various software modules of this trainingsystem, and fulfilled communication between the simulation training system’senvironment configuration software, the teacher station, and the studentstation, and this provided the simulation training with good flexibility,versatility and scalability.
