摘要:
350 km/h中国标准动车组辅助变流器采用无互联线并网技术,提升辅助供电冗余能力。辅助变流器采用PQ下垂控制,以三相同步坐标变换的方式实现对供电母线电压的锁相,以有功功率实现对辅助变流器输出频率控制、无功功率实现对辅助变流器输出电压幅值控制的方式实现并网均流控制。该控制策略在 350 km/h中国标准动车组上进行了实车试验,试验结果表明:350 km/h中国标准动车组辅助变流器并网控制效果良好,在动车组辅助变流器启动、投切、负载变化过程中,动态响应快,均流效果好,满足动车组运行的要求。
Abstract:
The auxiliary converter of the 350 km/h CEMUs adopts wireless parallel technology, which improves the power supply redundancy. The auxiliary converter was controlled with PQ droop control. The phase-locking of supply bus voltage was realized with three-phase synchronous coordinate transformation mode, grid-connected flow control was realized by means of active power controlling frequency of auxiliary converter and reactive power controlling output voltage amplitude of auxiliary converter. A real-vehicle test had been conducted. The test results show that the 350 km/h CEMUs auxiliary converter has a good grid-connected control effect with fast dynamic response and nice current sharing effect in the process of starting, switching, and load fluctuation, which meets the requirements of the EMUS operation.
