摘　　要：分析了同相牵引供电系统的结构与原理,并提出了综合潮流控制器的一种设计与实现方案。该方案通过采用改进的瞬时无功功率检测方法,计算出补偿电流并通过控制背靠背的SVG系统实现同相牵引供电和电能质量综合治理。详细介绍了以FPGA为核心的综合潮流控制器的设计和实现方法,该控制器由先进的FPGA、A/D转换和IGBT等电路构成,通过对多路电压、电流实时输入信号进行采集和处理,由FPGA快速计算生成指令电流,最后再通过滞环调制方式控制背靠背的SVG系统从而实现同相牵引供电。仿真和实验验证了方案的正确性和有效性。The structure and theory of novel co-phase traction power supply system（ TPSS（ are developed and the design and realization scheme of integrated power flow controller （IPFC（ are proposed. The modified instantaneous reactive power detection method which could calculate the compensation current immediately is applied in the system. The back to back SVG system could achieve co-phase TPSS and comprehensive management of power quality according to compensation current. The design and realization of IPFC based on FPGA is introduced in detail.The controller is composed of FPGA,A/D conversion and IGBT circuits and so on ,and through the multiple voltages and current real-time signal acquisition and processing,the instruction current could be calculated by the FPGA quickly and after hysteresis modulation ,the co-phase TPSS could be realized.The correctness and effectiveness of the scheme are authenticated by simulation and experiment.
