Abstract :
Interference with the electric power system can disrupt stability in the distribution. Interference in the system can be in the form of interference in the form of short circuit interference in the transmission system, the release of the generator from the system, and so on. Therefore, a system defense scheme is needed to maintain the stability of the system, which is commonly called the defense scheme. Defense scheme is a protection scheme that is used to protect the system when abnormal conditions occur in the operating system. In this study, it will be discussed regarding the Under Voltage Load Sheding (UVLS) defense protection scheme using several load shedding schemes, namely the largest load shedding scheme, and the largest load shedding scheme other than in dustri. With the load shedding method using Under Voltage Load Shedding (UVLS) on the Jenponto-Punagaya channel, it is the backbone or main line and there is no backup in the energy transfer process. Furthermore, the sulbagsel system data is entered into DIgSILENT PowerFactory 15.1. to be simulated load shedding in accordance with the scheme that has been made on the Jeneponto Punagaya Transmission Line after the plant and experienced a voltage loss of 134,728 kV. Based on the simulation results of the application of the nearest load plant discharge including industrial power loss of 218.6 MW, the largest load scheme of voltage loss of 139,279 kV, and the fourth release scheme of multiple load shedding to Return to normal state of 152,350 kV. For the third and fourth schemes, it succeeded in raising the system voltage level beyond what the 2020 Electric Power System Network Rules allowed, which is 135 kV.
