Large Scale Static Generator Integration Impact on Protection Relay Operation at 132 kV Malaysia Transmission System

Power swing phenomenon's impact on distance relay operation has been reviewed in a synchronous generator environment. The objective of this paper is to study the impact of power swing phenomenon's impact on distance relay operation in the presence of the large-scale photovoltaic (LSPV) system. The analysis is performed through simulation basis and by observing the active power oscillation, rotor angle oscillation and impedance trajectory seen by distance relay. Hence, the integration of LSPV in rotating machine environment results in a huge change in power swing and fault characteristics causing mal-operation of distance relay.
