Abstract

An electric power system will get overload disturbance if a plant that was previously
able to supply power to a system that is outage, causes other plants that are still operating to
have the entire load of the system. This study aims to see the performance of under frequency
relay (UFR) that has been installed in the Bali system in overcoming overload disturbances,
namely in the form of generator outages according to the scenario that has been made. The
method used is to model the load shedding scheme using UFR in software and run according to
the scenario. The scenario referred to is a disturbance that causes one or more generators to
experience blackouts due to disturbances. The results of the analysis show that under the
frequency relay (UFR) installed in the Bali system it cannot return the system frequency to its
normal state, namely the system has a shortage of generating power with a steady state
frequency below 49.8 Hz in the 3rd, 4th fault scenarios. , and the 5th while the system has
excess power generation with a stable state frequency above 50.2 Hz at the 9th and 10th
disturbances.
