| 摘 要： | 近年来国内相继出现多起高速铁路车网耦合系统低频振荡,振荡严重时甚至导致动车组牵引封锁。针对多列CRH5型动车组升弓整备投入牵引网时发生低频振荡提出了一种有效抑制方法。首先,分析了多列CRH5型动车组同时升弓接入牵引网的多车网电气耦合系统特性。其次,基于改进自抗扰控制策略对车网系统负载CRH5型动车组整流器的控制器进行优化设计来抑制系统低频振荡。最后,相比原有动车整流器PI控制和传统自抗扰控制技术,在Matlab/Simulink平台下测试验证了基于改进自抗扰控制的多CRH5动车组升弓整备投入牵引网的车侧电气量发生低频振荡抑制的正确性和有效性。

| Abstract: | In recent years, many low frequency oscillation of high-speed railway vehicle-network coupling system occurred in China. When the oscillation was severe, it even led to Electric Multiple Units (EMU) traction blockade. This paper presents an effective method to suppress the low frequency oscillation when the multi-CRH5 EMU pantograph is lifted and put into traction network. First, the characteristics of electric coupling system of multi-CRH5 EMUs simultaneously connecting to traction network are analyzed. Next, based on an Improved Active Disturbance Rejection Control (IADRC) strategy, the controller of CRH5 EMU rectifier load of the vehicle-network coupling system is optimized and designed to suppress the low frequency oscillation. Finally, based on the IADRC, the correctness and effectiveness of vehicle-side electrical quantity low frequency oscillation suppression when multi-CRH5 EMU pantographs are lifted and connected to traction network are verified by comparing PI control and ADRC control technology under Matlab/Simulink platform.
