Abstract

The main challenge in electricity distribution in Riau and Riau Islands is the high incidence of power line faults. One effort to reduce power line faults is through the installation of FIOHL (Fault Indicator Overhead Line). FIOHL is a device used to detect faults on power lines, which can help quickly identify the location of the fault. In this study, PLN UP2D Riau plans to install 35 FIOHL units on 198 power lines. The objective of this study is to determine the priority order of power lines as the location for installing FIOHLs accurately. By using the Entropy method as a criterion weighting method and PROMETHEE (Preference Ranking Organisation Method for Enrichment Evaluations), the priority order of alternative solutions for determining the power lines can be obtained. The installation of FIOHL must meet eight criteria: number of outages, outage duration, Energy Not Served (ENS), number of outages without cause, feeder load, network length, number of customers, and keypoint ratio for each feeder. The number of customers has the highest weight at 0.175, followed by network length at 0.152 and ENS at 0.151. The priority locations for FIOHL installation using the PROMETHEE method show that the Maroko feeder ranks first with Phi = 0.6329, followed by the Laos feeder with Phi = 0.6247. The allocation of FIOHL installations across each Implementation Unit (UP3) includes 14 units for UP3 Bangkinang, 14 units for UP3 Dumai, 4 units for Pekanbaru, and 3 units for UP3 Rengat..

Abstract

Switching manuver adalah proses membuka dan menutup komponen-komponen pada Sistem Tenaga Listrik (STL) seperti Pemutus (PMT) dan Pemisah (PMS) sebelum dan sesudah pekerjaan instalasi kelistrikan, baik instalasi transmisi, pembangkitan dan distribusi yang bertujuan untuk memastikan keselamatan dan kelancaran pekerjaan instalasi. Gardu Induk (GI) Ngenang adalah GI yang berada pada sistem Bintan, di mana gardu induk tersebut memiliki desain khusus yang tidak memiliki Bay Penghantar 150 kV atau sering disebut Gardu Induk Cantol. Gardu Induk Ngenang terletak pada Line 2 Bay Penghantar Tanjung Kasam-Tanjung Uban dengan memanfaatkan line penghantar tersebut sebagai busbar 150 kV. Dengan kondisi tersebut maka ketika pemeliharaan Bay Penghantar Tanjung Kasam-Tanjung Uban 2 tentunya akan berdampak padam pada Gardu Induk Ngenang. Permasalahan timbul ketika ada pekerjaan perbaikan pondasi Lightning Arrester (LA) pada penghantar tersebut, di mana butuh pemadaman line penghantar selama 8 jam dengan durasi pekerjaan 6 hari. Hal ini tentunya sangat memberatkan dikarenakan Gardu Induk Ngenang harus padam 8 jam selama 6 hari. Tujuan dari penelitian ini yaitu untuk merancang prosedur khusus Switching Pembebasan Tegangan dan Pemberian Tegangan Penghantar 150 kV Tanjung Kasam-Tanjung Uban 2 dan Gardu Induk Ngenang agar dapat meminimalisir dampak padam yang ada di Gardu Induk Ngenang. Dengan adanya Prosedur Khusus Switching tersebut berdampak pada perbaikan kinerja System Average Interruption Duration Index (SAIDI) sebesar 89% dan System Average Interruption Frequency Index (SAIFI) sebesar 50% serta Energy Not Serve (ENS) sebesar 89%. Kata kunci: manuver, switching, gardu induk, K3, fokus pelanggan
