Simulation Design of Ungaran 500kv Substation Operation System Using Microcontroller

Abstract

Extra High Voltage Substation 500 kV is one part of the backbone of the electrical system in Indonesia, this happens because it supplies so many areas. In terms of these benefits it can be seen that the equipment in the substation must have high reliability so that the quality of electric power reaches the consumer optimally and consumers will not feel disadvantaged. Operation of a switching device at the substation to make changes to the system is called maneuvering. In the implementation of the substation maneuver, it must be in accordance with the Standing Operating Procedure (SOP), if a switching error occurs when the maneuver will be fatal for the electric power system and can cause harm to the company and consumers. Therefore we need a safety in the substation maneuvering process called interlock. In this final project, a simulation tool is made to apply the working principle of the interlock system to CB and DS in maneuvering voltage relief, voltage delivery maneuvers and load-based maneuvers based on the Arduino Mega 2560 as the central controller for the entire system circuit. This simulator tool has a fairly high level of work accuracy in accordance with SOP (Standing Operating Procedure). It is hoped that this tool can provide knowledge to the general public about the existing maneuvering system in the GI in maintaining electric power transmission systems well and easily understood.
