摘要

对高压电动机启动过程中发生的开关瞬态进行计算机模拟有助于确定电动机绝缘可能承受的电压应力。此外，由于在各种条件下进行现场测试的实际限制，最好采用模拟电机电路而不是使用实际电机本身进行开关测试。本文重点对异步电动机起动电流中断后的暂态状态进行了仿真。研究使用等效电路来模拟系统的各个组件，使用EMTDC(电磁瞬变仿真)程序，并研究了一个标准测试电路的IEC模型，该模型可用于进行实验室测试。

Computer studies of high-voltage motor switching transients

Computer simulation of switching transients which occur during starting of high-voltage motors is helpful in determining the voltage stresses which the motor insulation may be subjected to. Also, because of the practical constraints in performing field tests for various conditions, it is preferable to resort to simulating motor circuits rather than using an actual motor itself for switching tests. This paper highlights the simulation of the transient conditions in an induction motor following interruption of the starting current. Studies have been carried out using equivalent circuits which simulate various components of the system, using EMTDC (Electromagnetic Transient Simulation) program, and an IEC model of a standard test circuit valid for carrying out laboratory tests was investigated.
