摘要
对异步电机失电残余电压的产生进行分析;建立了异步电机失电残余电压仿真计算模型,并进行仿真计算;定量分析异步电机失电残余电压的幅值、频率及其随时间变化的关系,并进行实验研究。异步电机失压后,残余电压的频率将突变,且不断减小,其大小由转子的转速决定;失电残压的幅值与失电时刻电源的相位及电机参数等有关,并随时间衰减。仿真计算与实验测试结果一致。
In this paper, the generation of the Residual Voltage of asynchronous motor after AC Dump （ RVACD） was analyzed; the simulation calculation model wasestablished and simulation caculation was carried out; The frequency of the residual voltage will be changed suddenly and then decreased by and by; its value was determined by the rotor speed. The magnitude of the residual voltage is related to the power phase and other motor parameters and decayed. The consistency of quantitative analysis result of the time changing relat on of the magnitude and frequency for RVACD and experimental result was proved.
