Abstract Due to high harmonic current and large negative sequence current caused by high-speed electric railway, power quality is deteriorated. To solve this problem, a novel power quality compensator constituted by railway static power conditioner(RPC), two thyristor-controlled reactors and two thyristor-controlled 3rd filters is proposed. The RPC is only used to transfer active power and suppress partial harmonic currents. The thyristor-controlled 3rd filters are used to suppress third harmonic current and change the phase angle of power supply current. The thyristor-controlled reactors are used to change the phase angle of power supply current. The proposed power quality compensator has small capacity and low cost. Furthermore, based on working principle of the proposed power quality compensator, its equivalent electrical models are established in fundamental and harmonic domain. This paper analyzes the best capacity selection principle of RPC as well as the resonant characteristics of the whole system. Moreover, the actual simulation of Beijing-Shanghai high-speed electric railway power supply system is carried. Simulation results show that the study contents of this paper are feasible and valid.
