Design of a Hybrid Railway Power Conditioner with Co-phase Power Supply System

Abstract

With the widespread use and rapid development of electric locomotives, the negative sequence and excessive phase problems of traction networks have become increasingly prominent. A hybrid railway power conditioner system (H-RPC) for co-phase was proposed, And compared with the traditional RPC system. The paper analyzed its topology and compensation principle. The design of its key parameters was given. The analysis results show that H-RPC has better compensation effect than RPC. Finally, the correctness of the H-RPC compensation effect is verified by simulation.
