摘要

本文介绍了交流牵引电气化系统的完整模型。该模型由供电、斯科特变压器和自耦变压器以及悬链线系统组成。电机被模拟成异步电机。v/f控制用于实现电机速度。该模型在PSCAD/EMTDC中实现。通过对仿真结果的分析,指出了所建模型对牵引载荷、驱动装置和列车运动的准确性。结果表明,该模型可作为铁路交流电气化系统的设计规划工具。

Modelling of AC Electric Railway System using PSCAD/EMTDC
This paper introduces a complete model of the AC traction electrification system. The model consists of the supply, the Scott- and auto-transformers, and the catenary system. The motor is simulated as an asynchronous machine. The v/f control is used for achieving the motor speed. The model is carried out in PSCAD/EMTDC. Analysis of simulation results are introduced, which pointed out the accuracy of the proposed model for the traction load, drives, and train movement. The results show that the model can be a designing and planning tool for the AC electric railway electrification system.
