Transient Stability Analysis of a Combined Cycle Power Plant Using Etap Software

摘要

Recently in the operation of power systems, transient stability analysis has become a major issue because of increasing stress on power system. The transient stability analysis for large power system network is very difficult and highly non-linear problem. In this paper, different faults (like 3-phase faults, LG fault and sudden removal of generator) are considered at different bus levels in combined cycle power plant and the fault clearing times for stable operation of system (critical clearing time) are calculated by using the ETAP (Electrical Transient Analyzer Program) software.
