superconductor fault current limiter (sfcl) is an effective device to suppress high fault currents. this paper presents a comparative study of resistive and inductive fault current limiters from transient stability point of view.  appropriate location and type of the limiters in a hv substation is selected by a qualitative approach based on the equal area criterion. study system is simulated by...

Power system transient stability assessment (TSA) and control is a complex problem. TSA from the perspective of individual machine Kimbark curves forms distinctive approach. On other hand, constrained optimal power flow (TSC-OPF) has been adopted widely for determining preventive actions against instabilities under given contingency. This paper presents strategy control, which mainly integrates...

For transient stability analysis of a multi-machine power system, the Extended Equal Area Criterion (EEAC) method applies classic (EAC) concept to an approximate One Machine Infinite Bus (OMIB) equivalent system find critical clearing angle. The system-critical time can then be obtained by numerical integration OMIB equations. EEAC was proposed in 1980s and 1990s as substitute for time-domain s...

Preventive control actions for enhancing the transient stability of power system ensures under a given contingency. Generation rescheduling through constrained optimal flow (TSC-OPF) is one widely adopted preventive scheme. This study reports an approach enhancement using global methods. The proposed uses individual machine equal area criterion framework (IMEAC), which direct time-domain analys...
