摘　　要：为准确计算高压感应电动机断电重启时的电流及电磁转矩值,在αβ-dq两相坐标系下建立了高压感应电动机断电重启时的状态方程组。求解状态方程组得到了不同重启时刻电动机的电流值、电磁转矩值以及最不利重启时刻,为断电后高压感应电动机的安全可靠重启提供了理论依据。In order to accurately calculate the current and electromagnetic torque values of high-voltage induction motor during restarting,the state equation set of the motor during restarting was established based onαβ-dq coordinate system.The current and electromagnetic torque values of the motor at different restarting times and the improper restarting time are obtained by solving the state equation set.It provides a theoretical basis for the safe and reliable restarting of the high-voltage induction motor after power off.
