ANALISA JARINGAN DISTRIBUSI TEGANGAN MENENGAH DENGAN SISTEM SINGLE WIRE EARTH RETURN UNTUK WILAYAH TERTINGGAL, TERDEPAN DAN TERLUAR

Abstract

Indonesia's rural electrification rate (RER) is still low. This is due to the high cost of installing a conventional three-phase or single-phase power supply in distributed rural loads. However, the Rural Energy Agency and the National Utility have made many efforts to address this issue. To this end, this document proposes a Single Wire Earth Return (SWER) electrification scheme for the electrification of a selected village, namely Serang, Banten. Field data were collected and used to design a potential SWER distribution network. A mathematical model representing SWER for Serang, Banten was developed and simulations were performed to determine soil potential and soil resistance. These two are important every time you install a HEAVY line. In addition, a technical and economic comparison was made in order to determine the short-term costs of the proposed SWER with the existing single-phase two-wire (SPTW) system. The technical and economic analysis shows that the proposed SWER system will achieve a cost saving of 50% compared to the installation of the SPTW system for Serang Banten electrification.
