Abstract: Stability is one of the requirements of an electrical power system which can be considered good/ideal, One disturbance that can affect stability is the outage of the system generator. To overcome this problem, load shedding is performed, The load is released in a simulation aimed at bringing the frequency back to the authorized value after the disturbance has occurred. The power plant that experienced a trip in this study was the largest Lampung unit of the generator Tarahan 4.When the generator Tarahan 4 has been tripped, the frequency system is falls and stabilize at 48.8 Hz.Therefore its necessary to release the load so that the system frequency returns to the authorized value, which is from 49,8 Hz to 50.2 Hz. Based on the results of simulation after setting the frequency relay, by releasing a load of 152.2 MW, the frequency was stable at 50.074 Hz . So it can be concluded that the frequency relay setting has been able to return the system frequency to allowable value.
