摘要
针对电动机失电存在残余电压和异步电动机双电源开关转换时可能会产生较大的合闸涌流和过电压问题,通过Matlab仿真软件研究电动机负载电源转换的暂态特性,寻找备用电源合适的合闸时刻。对智能化自动转换开关(ATSE)控制器的设定具有一定的指导作用。
Because of the existence of residual voltage double power conversion of asynchronous motor, it may produce larger current and over-voltage, this paper researched the transient characteristics of power transfer in motor load by Matlab simulation, and found out suitable swiching time of backup power supply, which has a certain guidance to the setting of intelligent aletomatic transfer switching equipment (ATSE) controller.
