Abstract

A disturbance in the power system can lead to a voltage instability in the system. Voltage instability in the system causes the system to operate abnormally leading to voltage collapse or total blackout in the entire system. This paper discusses voltage stability to anticipate disturbance with Static VAR Compensator (SVC) using transient simulation in ETAP 12.6.0 software. Load shedding scheme by using voltage relay is analyze when a massive generator disturbance occurs. Load shedding scheme is relayed to revert and stabilize the system voltage. The scheme will trip some of the high priority load from the system. 15 MVA or 12,32% of the whole load will be saved to prevent the load from tripping used SVC with 30 MVAR ratings. Based on the analysis, SVC can be used to minimize load shedding for power system disturbance anticipation.
