Abstract

Currently, the transition between renewable energy sources and PLN sources at PT LBN is done manually by conducting scheduled monitoring. However, this method is less efficient and depends on the readiness of the operator. Therefore, in this Final Project, the design and construction of an Automatic Transfer Switch (ATS) on a renewable energy hybrid grid system at PT LBN is carried out where the source switching is based on the battery voltage value so as to shorten the source switching time while protecting the battery from undervoltage conditions. The main components used in the construction of this ATS system are contactors, relays, relay control circuits, ESP32, LCD 1604, and voltage divider circuits. The result of this final project is an ATS system that has a voltage sensor error of 0 - 1.187%. The monitoring of the ATS system was also successfully accessed from near and remotely in real time. The ATS that was built has a faster source switching time than the manual method, which is 21.6 ms - 40.1 ms.

Abstract

Today, electricity is one of the important components to drive the industrial process and other daily human activities. While the continuity of power supply through the power system grid is impressionable from disturbances such as a short circuit. In addition, the rapid development of distributed generation (DG) technology triggers the industry to use DG technology to maintain power quality and support for industrial processes. This paper proposed the coordination of over current relay (OCR) considering distributed generation (DG) to provide an extraordinary protection system in an electrical system network. The relay is coordinated with the other relay equipment to enhance the system more reliable, secure, and stable. To examine the efficacy of the proposed approach, the radial distribution system model is utilized in this paper where the DG is installed in bus 6. To compute the protection coordination index (PCI) and coordination time interval (CTI), the DG capacity is varied from 100 KVA to 1000kVA. From the simulation result, it could be seen that the installed DG that allowed in bus 6 was 900kVA because the CTI value reached convergence value as of 0.294 second for higher DC capacity than 900kVA. Moreover, the higher of DG capacity was injected to electrical system, the higher of PCI values was obtained.
