Abstract

The protection system in electrical engineering is a crucial component in maintaining electrical reliability. The protection system is a vital component that needs attention. Its utility not only serves as a parameter for the reliability of the electrical system but also as a safeguard for electrical system devices, starting from power suppliers (Power Plants), interconnection networks, transmission networks, to distribution networks. In Indonesia, with the unique dynamics of the domestic market, periodic evaluation of relays becomes important. This study investigates the current status and dominance of relay usage in Indonesia. Using a literature study method, we broadly identify the functions, utilities, and applications of Over Current Relay (OCR), Ground Fault Relay (GFR), Differential Relay, and Reverse Power Relay in Indonesia's electrical system. This literature study outlines several types of relays in Indonesia and their dominant usage in the electrical system, providing insights for readers and institutions using relays in Indonesia's electrical system. The implications of this literature study are to broaden the knowledge of the authors and readers and to encourage continuous innovation. With an understanding of the types of relays in Indonesia's electrical system, strategic steps can be taken to improve the reliability and efficiency of the electrical protection system in Indonesia.

Abstract

All human activities depend on electrical energy. The use of new renewable energy in Indonesia is still around 15%, even though Indonesia has great potential for new and renewable energy sources, especially water-based alternative energy. PLTMH is one example of the utilization of new renewable energy from water sources. Turbine is one of the important components in PLTMH. This study aims to conduct a literature review on turbine types and trends in PLTMH design publications using the systematic literature review method.  The review results show that the crossflow type impulse turbine is most dominantly used in PLTMH, followed by the Pelton type. Other turbine types such as Francis, Vortex, Archimedes Screw, and undershot are used less frequently. The publication trend peaked in 2020, then declined moderately in the following years. As of May 2024, there are no new studies, indicating a change in focus or a decline in interest.
