中文摘要：

为解决高速铁路牵引供电系统负序不平衡问题,在传统基于铁路功率调节器（Railway Power Conditioner,RPC）补偿的基础上,针对所需补偿容量较大的问题,提出了多变电站RPC协同补偿的理论.并对该方法进行了详细证明,推导了在各种情况下的安装容量和补偿方法,该方法较单个牵引变电站所需RPC容量可降低1/3的补偿容量,从而减小了成本.最后,进行了仿真验证,结果表明,该多站协同补偿方法具有可行性和有效性.

英文摘要：

High-speed train traction power supply system causes serious negative current problem. Railway power conditioner （RPC） is efficient in negative sequence compensation. A novel power quality collaboration compensation system and strategy based on RPC is proposed. The minimum capacity conducted is 1/3 samller than traditional single station compensation. Simulation results have confirmed that the collaboration compensation system proposed can achieve a good performance at the negative sequence compensation with capacity and cost efficient.
