Enhancement of Reliability of Process Power Plant by Connecting SVC in Generator Bus during Grid Fault

Utpal Goswami, Dr.Pradip Kumar Sadhu, Dr. Suprava Chakraborty


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