Must strictly abide operate specification, should stop work immediately and identify the reason when have a unusual phenomenon in working. Start work again after clearing of fault.
必须严格遵守操作规程，操作时如发现有异常现象应立即停止工作，查明原因。有故障必须在排除后再继续工作。
A direct method considering transient voltage dip is proposed to calculate the critical clearing time (CCT) ensuring that voltages of post fault power system are higher than limit.
提出了一种考虑暂态电压跌落限制的直接法，快速求取保证故障后电力系统电压高于限值的故障临界清除时间(CCT)。
So the traditional stability analysis methods cannot be applied to the new condition. This paper proposed a new method to compute the probability distribution of fault critical clearing time.
这使得传统的稳定分析方法已不能适用于新的形势，为此提出了概率稳定分析这一新的课题。
