摘要
针对基于下垂控制的三相逆变器并联列车辅助供电系统,改进了其下垂策略,并构建了基于dSPACE实时仿真器的三相逆变器并联列车辅助供电系统半实物仿真平台,在该平台上进行了三相辅助逆变器并联控制器在变负载工况下的半实物仿真实验。结果表明,构建的基于dSPACE的逆变器并联列车辅助供电系统半实物仿真平台是可行的,同时,也验证了改进下垂策略的可行性和有效性。
The droop strategy of the three-phase inverters parallel train auxiliary power system based on droop control is improved, and the semi-practical simulation platform based on the dSPACE real time emulator for the three-phase inverters parallel train auxiliary power system is built, in which the semi-practical simulation experiments of the parallel controller of the three-phase auxiliary inverter with mutative load conditions are done.The experimental results show that the designed semi-practical simulation platform of the inverters parallel train auxiliary power system based on the dSPACE is feasible, and the feasibility and validity of the improved droop control strategy is validated.
