异步电动机残压的计算机仿真及试验研究

Computer Aided Simulation and Test of Residual Voltage for Induction Motor

利用异步电动机的准确数学模型,对异步电动机断电时定子绕组的残压进行了计算机仿真;同时,对残压现象进行了实测,仿真结果与实测数据吻合。残压计算为自动二次重合闸装置的设计人员提供了理论依据,也是分析异步电动机电容制动过程的基础。

The paper simulates the residual voltage of stator winding during the break period on the basis of accurate mathematical model for induction motor. At the same time, the real data of residual voltage is also tested, and the two results match well. The computation of residual voltage offers the theoretical foundation to the design of automatic secondary reclose, and it is also the analysis basis for capacity braking.
