| 摘 要： | 以高速动车组项目为背景,研究和实现了辅助变流器并联系统的控制策略。利用PQ下垂法,通过计算各辅助变流器的输出有功功率和无功功率,对其输出电压和频率进行下垂特性控制,以实现无互联线的辅助变流器并联。从高速动车组辅助变流器并联满功率地面组合试验结果来看,该并联系统运行稳定,动态响应快,均流效果良好。

| Abstract: | The control strategy of parallel inverters was analyzed and implemented with the background of high-speed EMU program. By calculating positive power and negative power, output voltage and frequency of auxiliary inverters were controlled with the PQ droop method to implement auxiliary inverters in parallel with no control interconnection. Result of the full-power ground combination experiment to high- speed EMU parallel inverters show that the parallel system has stable operation, fast transient response and good current-sharing. |
