电铁供电系统有源电力滤波器动态补偿性能的仿真研究

摘要

This paper presents the performance of active power filter and discuses the principles of operation of it for restraining the electrified railway system harmonic current. At first, fundamental princi-ples of active power filter is introduced. Secondly, in consideration of electric locomotive have random variation character. The simulation of electrical railway system model is presented with MATLAB/SIMU-LINK using active power filter when load changes. The simulating results prove the active power filter put forward in the paper can realize dynamic harmonic current compensation efficiently.%本文对用于电气化铁道牵引(简称电铁)供电系统的谐波抑制的有源电力滤波器进行了分析研究，首先介绍了有源电力滤波器的基本原理，其次考虑到电铁供电系统中电力机车这个负荷是随机变化的，在MATLAB/SIMULINK仿真软件下，对在负荷变化时有源电力滤波器的谐波动态补偿性能进行了仿真，仿真结果表明所提出的有源电力滤波器能有效地实现电铁供电系统的谐波动态补偿。
