Critical clearing time是什么

Web(2024). The critical clearing time (CCT) or critical fault clearing time (CFCT) is the longest amount of time over which the fault may remain uncleared. After this time the machines may not regain synchronism, or the system may settle at an undesired equilibrium point. A number of methods exist in the literature to classify the post-fault state.

Fault clearing time (FCT) and critical clearing time (CCT) are significant parameters so as to preserve power systems transient stability. The FCT is the time upon which the fault is cleared following the fault occurrence, while the CCT is the fault clearing time upon which the system is at the critically stable level.
