Abstract :
To maintain system frequency fluctuations caused by changes in load with a fast response, an Automatic Generation Control (AGC) system is needed. Implementation of AGC activation in the Java Madura Bali system which is one of PLN's Anti Black Out breakthrough programs in the context of strengthening defense to prevent widespread blackouts due to disturbances. The existing Load Frequency Control (LFC) system at the Tambak Lorok PLTGU has not been operating for a long time, so it was chosen to implement the activation of the AGC system which will be controlled automatically by the Dispatcher Java Control Center (JCC) through the SCADA system control scheme. It is necessary to do commissioning & point to point SCADA signals and then realtime loading testing to see the fast response of the AGC SCADA system at the Tambak Lorok PLTGU generator. When testing realtime loading, the frequency of the Java-Bali system is conditioned to be at 50,154 Hz and 49,819 Hz. The data is used as a reference for the successful implementation of AGC activation for other PLTGUs in the hope that other PLTGUs can immediately contribute to the AGC system. With fast AGC activation, the purpose of system operation will be achieved better, namely the quality of the Java Madura Bali electrical system frequency is maintained at 50 Hz. AGC is also a solution to the challenges of intermittent renewable energy in the future.
