摘要
介绍了电力机车辅助电源传动试验台系统,对系统组成和工作原理进行了说明。其采用PWM整流器作为系统负载,利用PWM整流器调节被试逆变器的输出电流来进行各种工况的试验,PWM整流器采用了基于交流电压定向的电流控制策略实现解耦控制,并采用了预测电压法提高控制性能。
A new transmission testing device for electric locomotive's auxiliary converter system was introduced,and structure of electric locomotive's auxiliary convertor system and its working processes were illustrated.PWM rectifier was used as load unit to regulate inverter output current for implementing various test conditions,current control of which was based on AC voltage orientation theory to realize decoupling control,and voltage-forecasting method was used to improve control system performance.
