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)
