摘　　要：针对电气化铁路中由于牵引网电压升高导致列车再生制动失效的问题,提出一种基于储能装置的列车再生制动失效抑制方案。基于该方案装置的拓扑结构,提出以供电臂末端电压为主要判据的装置控制策略;设计了传输有功和吸收无功模式下变流器以及储能装置的控制方法;并对列车再生制动失效抑制方案以及装置控制策略的正确性进行仿真验证。结果表明,该方案既能通过降低牵引网末端电压来抑制列车再生制动失效,又可以支撑牵引网末端电压。With respect to problems of train’s regenerative braking failure induced by increasing of traction network voltage in electrified railway,the paper raises a scheme for suppression of storage-device based train’s regenerative braking failure.And on the basis of this scheme,proposes a device control strategy based on the end voltage of feeding section,designs the control methods for converters and energy storage devices under working modes of active power transmission and absorption of reactive power,simulates and verifies the correctness of suppression scheme and the device control strategy for train’s regenerative braking failure.The results show that the scheme is able to either suppress the train’s regenerative braking failure by reduction of end voltage of traction network or support the end voltage of traction network.
