摘　　要：地铁再生制动能量逆变回馈方式具有节能效果好,投资小,得到了越来越多的工程应用。对常规各种能馈方案进行了对比分析,提出一种非对称二重化串联结构的制动能量分散回馈方案,并对该方案的能量流向、变流器损耗、系统转换损耗进行了对比分析,本文所提的方案较常规方案成本及转换效率都具有明显的优势。同时根据该并网节点的特殊性,对本方案的能馈逆变器可运行场景进行了探索,其可工作在能馈模式、线路分散无功补偿模式、0.4kV侧本地负载谐波补偿模式及各种混合运行模式。并综合各种运行模式的控制需求给出了系统整体的控制策略。最用通过Matlab/Simulink仿真软件对本文控制策略进行了仿真,验证了本文所提方案的可行性。The regenerative feedback mode of the regenerative braking energy of the subway has good energy saving effect and small investment,and has been applied more and more engineering applications.The conventional energy-feeding schemes are compared and analyzed.A braking energy dispersion feedback scheme of asymmetric double-series series structure is proposed.The energy flow direction,converter loss and system conversion loss of the scheme are compared and analyzed.The proposed scheme has obvious advantages over the conventional scheme cost and conversion efficiency.At the same time,according to the particularity of the grid-connected node,the operating scenario of the energy-supplied inverter of the scheme is explored.It can work in the energy-feeding mode,the line dispersion reactive power compensation mode,the 0.4kV side local load harmonic compensation mode and Various mixed operating modes.And the control requirements of various operating modes are combined to give the overall control strategy of the system.The control strategy of this paper is simulated by Matlab/Simulink simulation software,which verifies the feasibility of the proposed scheme.
