AB  - Problem statement: The critical clearing time provides very important role of the
robustness in power system. The Static Synchronous Compensator (STATCOM) has been accepted to
be equipped in modern power system. This study presents the method to evaluate the Critical Clearing
Time (CCT) of the system equipped with a Static Synchronous Compensator (STATCOM).
Approach: The parameter on STATCOM is modeled in energy function. The presented energy
function is applied to determine CCT of the system. The verification of the proposed method is tested on
sample system. Results: The maximum generator rotor angle of the faulted system without a STATCOM
is continuously oscillation and the maximum value is much more than the system with a STATCOM.
Conclusion: STATCOM based the proposed nonlinear control can damp power system oscillation.
