异步电机T_e-s曲线临界值求取的三种方法

介绍了异步电机Te-s曲线临界值求取的三种方法:不等式法、电路法、导数法。不等式法演算简单,但易忘掉异步发电机情形,无物理意义;导数法演算复杂,也无物理意义;电路法演算最简单,且有物理意义,可谓最佳方法。

Three Methods to Solve Critical Values of T_e-s Curve of Asynchronous Machine

This paper introduces three methods of solving critical values of T-s curve of a- synchronous machine, i.e. inequality method, circuit method and derivative method. The de- rivative method is complex to operate and has no physical meanings. The inequality method is simple to operate and has no physical meanings, but is easy to forget the case of asynchronous generator. The circuit method is easiest to operate and has physical meanings, which is the best one of all the three methods.
