电力系统中异步电动机临界转差的简捷计算法

SIMPLE AND DIRECT CALCULATION OF ASYNCHRONOUS MOTOR CRITICAL SLIP IN POWER SYSTEM

根据最大功率条件和小扰动法，提出了一种较常规方法更为准确、简捷的异步电动机临界转差计算方法。所获结果可作为判断电力系统中异步电动机临界失步和临界电压失稳裕度的依据。

This paper,based on the maximum load power condition and the small disturbance analysis,introduces a calculation method of asynchronous motor gcritical slip.It is more acurate,more simple and direct than usual methods.The calculation results can be taken as the judging basis for the abundance of motor critical instability and critical voltage instability in power system.
