摘　　要：在考虑感应电动机负荷模型的情况下,提出了暂态电压稳定快速判据。该判据通过判断感应电动机故障切除时刻端电压与暂态稳定临界电压和暂态不稳定临界电压的关系,来判断暂态电压稳定性,从而缩短判断时间。用BPA软件进行仿真分析,验证了所提出方法的准确性和快速性。Considering the induction motor load models,a quick criterion for transient voltage stability is proposed.The transient voltage stability is assessed by considering the relationship between the terminal voltage of induction motor at fault clearing time and the transient stability critical voltage,as well as the transient instability critical voltage to reduce the assessment time.The accuracy and efficiency of the criterion are verified by the simulation through BPA.
