Abstract

Fault clearing time plays an important role in maintaining power system stability and process survivability during major systemfaults under a variety of system configuration and topologies. Grid disturbance in the power system presents a very distinctchallenge; lack of a utility interconnection hinders the system’s ability to recover from loss of generation. The key factor in plantsurvivability during a grid fault is optimal use of a fast acting governor and a Flexible Alternating Current Transmission Systemdevice (FACTS) to maintain power system stability. In this paper, the core objective is to increase the critical fault clearing timeof captive generator sets during a grid fault without violating the transient stability criteria recommended in IEC standards. Asa remedial measure, a static VAR Compensator (SVC) was connected to the generator bus. For simulation purposes an IEEEGeneral Steam-Turbine (STM) governor model and an IEEE AC5A excitation model were considered. During a grid fault thetransient performance of captive generator sets was observed with and without connecting SVC in generator bus.
