摘　　要：针对高速电气化铁路牵引供电系统由于不平衡负荷和整流引起的电网较大负序和谐波电流的电能质量问题,提出一种基于铁路功率调节器(railway static power conditioner,RPC)的新型电能质量补偿系统,详细介绍和分析了该新型补偿装置的拓扑结构和负序补偿原理,并对该新型结构的主电路参数设计方法进行讨论。最后根据高速铁路的实际运行情况,运用文中的参数设计方法设计参数,搭建仿真模型。仿真结果证明了新型电能质量补偿装置补偿原理及其参数设计方法的正确性。To eliminate power quality degradation due to large negative sequence current and harmonic current caused by unbalanced load and rectifier load in high-speed railway traction power supply system, a novel power quality compensation system based on railway static power conditioner （RPC） is proposed. The topological structure and the principle of negative-sequence compensation of the proposed power quality compensation system is presented and analyzed in detail, and the design approach of its main cuicuit parameter is discussed. Finally, according to actual operation condition of high-speed reailway, the parameters of the novel power quality compensation system are designed and corresponding simulation system is constructed. Simulation results show that both compensation principle of the novel power quality compensation system and the design approach for its parameters are correct.
