PSCAD/EMTDC-Based Modeling and Simulation of Urban Rail Transit Train Electrical Characteristics

基于PSCAD/EMTDC仿真软件,首先采用面向对象的建模方法对城市轨道交通车辆进行了电气建模,所建模型包括主牵引系统、制动电阻、滤波电路、辅助系统、阻力计算、行驶控制等诸多单元;然后基于该模型利用上海轨道交通某车辆参数进行了仿真和校验,仿真结果表明所建立的仿真模型具有较高的仿真精度,仿真数据与实测数据一致,能够准确地模拟出车辆在不同状态的电气特性与行使特性.

Based on PSCAD/EMTDC, the paper first presents an object-oriented modeling method for urban rail transit vehicle electrical modeling, the model including the main propulsion system, brake resistors, filter circuits, auxiliary systems, resistance calculation, driving control and many other units. A vehicle simulation and test based on Shanghai Metro parameters were made with the model. The simulation data are consistent with the measured data, which proves the established simulation model to be able to simulate accurately the vehicles in different electrical characteristics and exercise characteristics.
