Analisis Penerapan Fault Detection Isolation and Restoration untuk Penurunan Nilai Saidi (Studi Kasus PT PLN Unit Pelaksana Pengatur Distribusi Sumatera Utara)

Abstract

The continuity of electric power distribution needs to be considered in order to achieve the level of system reliability. The implementation of Fault Detection Isolation and Restoration (FDIR) is a smart way to improve system reliability and efficiency of distribution system operations. FDIR is a distribution network automation system that automatically performs the function of opening and closing the Load Break Switch (LBS) when a disturbance occurs by quickly detecting interference so that it can isolate and speed up fault recovery with load maneuvers. The purpose of this study is to determine the effect of FDIR application and analyze how SAIDI compares and duration of outages before and after FDIR application The results of the analysis show that there is a comparison of outage time and SAIDI before and after FDIR implementation. On the TT.05 feeder before FDIR, the average outage time was 22.15 minutes, after FDIR it was 10.70 minutes. Decreased average outage time by 51.745%. The average SAIDI before FDIR was 7.38333 minutes/customer, after FDIR was 3.56275 minutes/customer. The average decrease in SAIDI was 51.676%. In the DA.06 feeder before FDIR, the average outage time was 24.31 minutes, after FDIR it was 11.25 minutes. Decreased average outage time by 62.829%. While the average SAIDI before FDIR was 8.10417 minutes/customer, after FDIR it was 3.01243 minutes/customer. The average decrease in SAIDI was 53.723%. The magnitude of the percentage decrease shows the results of implementing the FDIR system. Effective FDIR implementation can significantly reduce outage duration and SAIDI to improve system reliability.
