Abstract An integrated compensation system based on two-phase three-wire converter was proposed to compensate negative sequence and harmonic currents for the high-speed railway traction system. In the proposed compensaor, two step-down transformers are connected to two feeder sections to form two single-phase voltages, which are connected to the two-phase three-wire converter through two inductors. This converter contains three switch arms, one of which is connected to the common ground wire of two single-phase voltages. So, the two-phase converter saves a switch arm comparing with two conventional single-phase converters. In this paper, the novel compensation structure was proposed and analyzed, and related electric model was built to analysis the operation principle of two-phase three-wire converter and the compensation principle of proposed system. The real-time negative sequence and harmonic detection and control method for the system was proposed. Simulation and experimental results have proved the validity of the proposed system and its methods.
