critical fault-clearing time

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)。

The formulae for SMIS are derived and verified by case simulation, the solution of critical clearing time (CCT) of three-phase short fault in MMS is theoretically discussed.

对单机无穷大母线系统进行了公式推导和仿真验证，从理论上探讨了多机系统的三相短路故障临界切除时间求解方法。

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。
