一种判断静态电压稳定性的新方法

A new method of judging static voltage stability

文中对简单系统的供应侧和负荷侧Ｖ-Ｉ特性进行了研究，得出了利用平衡点处两曲线的斜率比较判断电压稳定的新方法，并成功地将该方法应用于复杂系统。算例验证了其有效性。

This paper studies V-I steady-state charac- teristic curve of provision & desideration. It presents a new method to judge steady-state voltage stability by com- paring slopes of two curves at the balance points. The computational result shows the effectiveness of this method in the complex system.
