Abstract :
The Depok-Cawang subsystem is only supplied by the Interbus Transformer (IBT). However, sometimes there is a disturbance in one or more of the IBTs, so that the other IBTs will be overloaded. If the IBT is still operating beyond its operational limit for a long period of time it will cause a total blackout. To prevent blackouts, a defense scheme or defense scheme is applied. One type of Defense scheme is Over Load Shedding. OLS (Over Load Shedding) is a protection from the transmission network which has the aim of preventing widespread blackouts by releasing certain predetermined loads. This study discusses the Over Load Shedding scheme on IBT in the Depok-Cawang subsystem. The method used is a quantitative method where interviews and observations (data collection) related to the discussed OLS scheme are carried out. This study aims to make the DepokCawang subsystem so that there is no overload due to the tripping of 2 IBTs and to analyze the scheme of overloading the 3 Cawang IBT on the Depok-Cawang subsystem there is an overload. In this study, the total result was 261.7 MW from 3 stages, stage 1 was 135.1 MW, stage 2 was 32.2 MW and stage 3 was 94.4 MW.
