客货两用型的米轨机车对牵引变流器的体积和模块数量有着严格的要求,因此其主电路采用了两重四象限带5个逆变器的模式,并首次将辅助逆变器和列车供电逆变器都集成在牵引变流器中。针对米轨机车牵引变流器主电路的创新设计可能带来的过压、过流等影响,本文以出口马来西亚的Eloco型电力机车为例,对其辅助逆变器和列车供电输出特性进行了仿真研究。仿真结果表明其辅助逆变器和列车供电的控制效果能较好地满足功能需求。
Multi-purpose passenger and freight rail cars on the traction converter of the volume and the number of modules has strict requirements, so its main circuit uses a two quad-band with five inverter mode, and for the first time the auxiliary inverter And train-powered inverters are integrated in the traction converter. In view of the possible over-voltage and over-current caused by the innovative design of the main circuit of the traction converter of the rice-rail locomotive, this paper takes the Eloco electric locomotive exported to Malaysia as an example and analyzes the output characteristics of its auxiliary inverter and train power supply simulation Research. Simulation results show that the auxiliary inverter and train power supply control can better meet the functional requirements.
