Research And Development Of The Power Supply Simulation Module For The Subway OCC Power Dispatching Simulation Training System

With the rapid development of urban rail traffic, in order to meet the requirements of the subway rail transit for dispatching personnel, and train qualified subway dispatching personnel faster and more, it is urgent to establish perfect training system, develop the corresponding dispatching training device. The subway OCC electric power dispatching simulation training system is designed for the subway power dispatch personnel to provide a good training platform, which can train qualified subway power dispatch personnel more rapidly, conveniently and completely.This paper was on the research and develop of power supply simulation module, which is one of important modules in the electric power dispatching simulation training system. The power supply simulation module could be divided into electric power system modeling module, electric power systems computation module and interlocking system with control module. This paper adopted ac,dc separated processing method, set up the relevant ac,dc circuit model of the power supply system respectively, the dc circuit model used traction power supply calculation, the ac circuit model used power flow calculation, and designed the interlocking and control function between the electric equipments as well as running system in the power supply system logically, finally realized the real-time monitor and dispatching function of the power supply equipments.Finally, this paper combined with the power supply wiring diagram and routes operation design data of chengdu subway line1, through the interlocking with the subway OCC dispatching simulation training system and environment control dispatching simulation training system, completed simulation of the ac,dc power supply system model and the interlocking and control functions respectively. The ac,dc power supply system simulation results are given at different times, among them, the dc side gives the power system operation data under different departure intervals, such as the up and down traction net voltage, rail voltage and the traction substation feeder current; the ac side gives the power supply line current, bus voltage, power consumption value and so on at different times. All the simulation results are in line with the subway traction power supply system and subway power operation units operation data.Based on the module, the electric power dispatching simulation training system realizes smooth development.The research and development of the power supply simulation module provides the OCC simulation training system a virtual power supply system, and a good training platform for training the power dispatching students, so as to realize the joint training among the power dispatching, train dispatching and environment control dispatching.
