摘　　要：针对高速化铁路牵引系统产生的大量负序与谐波电流,提出了一种能够进行大容量功率转移、负序补偿与谐波抑制的电气化铁路功率调节器(railway static power conditioner,RPC)结构。首先分析了针对V/V牵引变压器的RPC系统负序补偿原理,建立了其数学模型和控制原理图,重点分析了控制器参数变化对系统稳定性和闭环跟踪能力的影响,为参数的合理选取提供了理论依据。最后进行了仿真验证,仿真结果验证了分析的正确性。In allusion to a great deal of negative-sequence and harmonic currents resulted in high-speed railway traction system, a railway static power conditioner （RPC） structure, which can perform large capacity power transfer, negative-sequence compensation and harmonic elimination, is proposed. Firstly, the principle of negative-sequence compensation of RPC system for V/V traction transformer is analyzed and its mathematical model and the schematic diagram of its control are built; then the influences of controller parameter variation on stability and closed-loop tracking ability of RPC system are emphatically analyzed to provide theoretical foundation for the selection of parameters; finally simulation verification of the proposed structure and model is carried out and the correctness of above-mentioned analysis is verified.
