| 摘 要： | 文章提出了一种可以描述故障后系统稳定程度的灵敏度指标,根据系统稳定性逐渐恶化指标趋于零的特点,计算了系统部分参数的临界值;根据稳定指标与故障切除时间在一定范围内的良好线性关系,估算了系统故障临界切除时间;并在单机无穷大系统与10机典型新英格兰系统下进行验证,证明了该方法的正确性。

| Abstract: | The paper brings up a type of sensitivity index which can describe system's stability after failure,calculating some parameters' critical value of the system according to the characteristic which worsens gradually to zero in accordance with the system stability.This article also calculates system failure critical clearing time according to good linear relationship between stable index and failure removal time within some certain limits.What is more,this article also proves the correctness of the method thro... |
