接入可再生能源的多端口铁路功率调节器

Multi-port Railway Power Conditioner With Access to Renewable Energy

为实现铁路系统与可再生能源系统的互惠互利,提出了一种可再生能源接入的多端口铁路功率调节器(MP-RPC),实现了铁路系统的就地取电和负序补偿。提出并分析了MP-RPC 5种经典运行模式下的潮流管理策略。MP-RPC的关键部件是三端口隔离DC/DC转换器,可以用于隔离和功率传输。最后,在实验室搭建了牵引供电平台和仿真样机,对MP-RPC的拓扑结构和控制方法进行了有效验证。

To achieve the mutual benefits between railway systems and renewable energy systems,a multi-port 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.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.
