不同异步电动机模型对电压稳定性分析的影响

The Effects of Asynchronous Motor on Voltage Stability Analysis

首先给出了一种能完成大范围连续追踪电力系统平衡瓣流形、确定系统临界电压失稳点的新算法。借此对采用不同异步电动机模型研究电力系统电压稳定性时，得出的不同结果进行了分析和比较。此外，还提出了一种简捷计算电动机临界转差ｓｃｒ的新方法。

A new algorithm is presented . It can accomplish tracing the equilibrium solution maniflod, search- ing for the critical point of system instability. The effects of asynchronous motor models on voltage sta- bility analysis is studied by means of this new algorithm. A simple and direct calculation method of asyn- chronous motor critical slip is also provided .
