Multiport Railway Power Conditioner and Its Management Control Strategy With Renewable Energy Access

To achieve the mutual benefits between railway systems and renewable energy systems, a multiport railway power conditioner (MP-RPC) with the renewable energy access is proposed to realize the on-site power consumption and negative-sequence compensation. Its power-flow management strategy with five classic operation modes is proposed and analyzed for MP-RPC. The key part of MP-RPC is three-port isolated dc/dc converters, which can be used for the isolation and power transmission. Through the small-signal modeling and analysis of the three-port converter, the port power control strategy with feed-forward decoupling is applied. The coupling system is decoupled into two independent control loops based on the feed-forward decoupling matrix, which can effectively improve the dynamic performance of system. Finally, the traction power platform and simulated prototype are built in the Laboratory, and the topology and control methods of MP-RPC are verified effectively.
