SIMULATOR MODEL LINEAR SISTEM TENAGA LISTRIK MULTIMSIN

The Electric Power System (STL) generally consists of several generators (multi-machine systems) that are interconnected by a transmission line. The purpose of the interconnection is to ensure continuity of availability for the increasing demand for electric power consumption [1]. In a multi-machine power system, the disturbance which occurs is not only a change in load but can be in the form of a short circuit, load termination, line termination, and others. To identify and fix problems that occur in the Power System, a multi-engine power system simulator is designed. In this simulator a multi-engine linear model will be designed starting from generation, distribution, and transmission. To distribute energy with a good quality, the system must work optimally by maintaining the stability in the Power System. The good quality of electricity distribution can be seen from the minimal disturbance that occurs. Therefore the function of this simulator is to find out the disturbances that occur, find the interactions between machines, the dynamics of rotor between machines, then handled in the simulator. After the disturbance is resolved, it will result in the disappearance of the disturbance, creating stability, and also returning system operations to normal. With normal operation, electrical energy can be distributed properly. The use of a simulator is a way of representing an electric power system into a linear model in a simulator to improve the performance of the electric power system, optimize process, improve safety, test theory, solve problems, and maintain stability so that the electric power system operations can work properly.
