摘要 永磁同步牵引传动系统是轨道交通车辆稳定运行的重要组成部分,由于车辆经过断电区时,供电系统会出现短暂失电而引起母线电压突变,对牵引系统造成电流冲击以及LC振荡,甚至触发系统发生重大故障,影响系统运行。为使车辆能够平稳穿越断电区,该文通过建立轨道车辆永磁同步牵引系统穿越断电区的等效电路,推导出系统进入断电区前后的数学模型,并在此基础上提出一种通过整流发电稳定母线电压穿越断电区的控制策略,避免关闭牵引系统和断开主接触器,同时降低驶离断电区时母线电压突变,从而减小牵引系统的冲击及振荡。仿真和试验结果验证了所提控制策略的有效性和可行性。

Abstract:Permanent magnet synchronous motor (PMSM) traction drive system is an important part of the stable operation of rail transit vehicle. When the vehicle passes through the power-off area, the power supply system will temporarily lose power and cause the bus voltage mutation. Such mutation will bring current shock and LC oscillation to the traction system, and even trigger serious faults of the system, affecting system operation. In order to enable the vehicle to pass through the power-off area smoothly, this paper establishes the equivalent circuit of the PMSM traction system traversing the power-off area, and deduces the mathematical model before and after the rail transit vehicle traction system enters the power-off area. On this basis, a control strategy for stabilizing the bus voltage passing through the power-off area by rectifying power generation is proposed. As a result, the closing of the traction system and the disconnection of the main contactors can be avoided, and the sudden change of bus voltage when passing through the power-off area is reduced, thereby reducing the impact and oscillation of the traction system. Simulation and experimental results verify the feasibility and effectiveness of the proposed control strategy.
