Abstract:

为了在不同备用电源下均能够尽可能地抑制感应电机电源切换中的冲击问题,有必要寻求最优电源切换方式,并在考虑开关动作时间下确定最有利切换时刻,为此,需要对断电后定子残压及其与不同备用电源间的电压差和相角差进行更加准确的定量研究。本文首先根据感应电机断电后的定子电流实测波形,发现电机断电后依次进入两个阶段——定子两相不对称瞬态和转子自由运动阶段,这种考虑必然提高定子残压的准确定量计算;然后,基于感应电机对称、不对称空间矢量模型,对断电过程两个阶段分别进行深入的解析推导,求得定子残压解析表达式;最后,重点研究定子残压及其与不同备用电源间的电压差和相角差特性,据此确定最优电源切换策略和最有利切换时刻,并通过感应电机电源切换实测结果验证了所得结论的正确性和可行性。
