Abstract

This research deals with the islanding scheme design of DKI Jakarta and Banten power system which aim to improve the rate of success in islanding formation when distrubance hit. Islanding scheme is the last option in corrective control that devide electrical system into several regions during disturbance to maintain the electrical system stability. The islanding scheme design method is based on generator coherency, severe connections, and active and reactive power balance. This islanding scheme is designed in 2 steps for 48,3 Hz and 48,1 Hz. In the first step, DKI Jakarta and Banten will be separated from Jawa Bali and in the second step the system should be divided into 4 islands due to generator coherency. Based on simmulation in Digsilent, this islanding scheme design could keep the stability of frequency and rotor angle of DKI Jakarta and Banten system.

Abstract

Pantry Feeder reconfiguration at the Cipinang substation requires readjusting its relay parameters so it can work fast, selectively, and sensitively. The conventional relay parameter calculation method requires a manually iterative process, which may result in inaccuracy. To avoid this error, the parameters of the main relay (Relay CBO E146) and the backup relay (Relay Incoming Feeder) at the Pantry Feeder are set using the metaheuristic method, in this case the Firefly Algorithm. This algorithm's goal is to find the shortest relay coordination time given the relay working time limits and coordination time intervals. The optimization results obtained were validated using the ETAP application and compared with the results of conventional parameter calculation at four different fault points. The Firefly algorithm method can produce faster yet still selective relay coordination with a coordination time interval are 0.273; 0.349; 0.389; 0.456 seconds, while the conventional method is 1.072; 1.162; 1.302; 1.482 seconds.
