Abstract:

高速铁路车网耦合系统出现电压低频振荡现象,导致多个动车所的多台动车组牵引封锁,目前对其机理研究处于初期阶段。首先推导“牵引网-动车组”耦合系统的状态方程以及瞬态能量平衡方程,判定车网开环系统的稳定性,并采用小增益定理分析电压振荡的影响因素。接着,基于十导体链式电路搭建精确的高速铁路全并联AT(autotransformer)供电系统模型,并基于瞬态电流控制建立CRH3型动车组电气模型;在此基础上,实现车网系统的互联,并仿真再现电压振荡现象。随后,通过调节动车组控制器参数及负荷分布实现电压振荡的抑制,并分析调节控制器PI参数抑制电压振荡的局限性。最后采用FFT及Prony分析的方法实现了振荡电压低频成份的辨识。
