摘要针对电气化铁路给电网带来的低功率因数、高谐波含量和负序电流的问题, 提出了在每个牵引臂安装由静止无功补偿器和混合有源滤波器有机组成的新型并联混合补偿装置。该装置结合静止无功补偿器和混合有源滤波器两者之长, 前者动态补偿无功电流并抑制负序电流；后者由无源滤波和有源滤波构成的注入式混合有源滤波器, 降低了工程成本和实现难度, 并有效抑制了谐波。文中分析了其拓扑结构和补偿原理, 并详细介绍了其无功控制方法。将该系统投入牵引变电站运行, 对比分析了系统投入前后的波形和数据, 证明了该综合补偿系统对改善电网电能质量的有效性和可行性。

Abstract：Due to the voltage flicker, harmonic pollution and low power factor caused by electric railway, power quality is deteriorated. To solve this problem, the paper proposes a novel comprehensive compensation system constituted by static var compensator (SVC) and hybrid active power filter (HAPF) to implement on-site power quality control. The SVC is used to compensate reactive power quickly and to remedy negative sequence current of power system. The HAPF is composed of the passive power filter and active power filter, and its cost and the difficulty of engineering are comparatively low. The new topology and operating principles of the system are analyzed, and the reactive power control is discussed in detail. The proposed comprehensive compensation system has been put into operation in a substation by means of comparing and analyzing the waveforms and data before and after the proposed system put into operation. The effectiveness and feasibility of the proposed system in the improvement of power quality are proved.

Key words： Electric railway power quality harmonic suppression reactive compensation active power filter (APF) thyristor controlled reactor (TCR)
