摘要

为了经济地设计定子绕组绝缘，当机器受到快速前置开关浪涌时，需要了解绕组内的电压分布。该模型基于行波法，能够以合理的精度预测绕组中任意点的浪涌电压。利用叠加原理，对一个每相有多个线圈的多相绕组进行了分析，并考虑了绕组其他相线圈的影响。

Prediction of transient behaviour of electrical machine windings

For economic design of stator winding insulation, a knowledge of voltage distribution within the winding, when the machine is subjected to fast fronted switching surges, is required. The proposed model, based on the traveling-wave approach, is capable of predicting surge voltages at any point in the winding with a reasonable degree of accuracy. The analysis is carried out for a multiphase winding that has a number of coils in each phase and includes the effect of coils in the other phases of the winding using the superposition principle.<>
