Reliability Analysis of 20 kV Distribution System in PT PLN (Persero) ULP Palopo Kota with Failure Mode and Effect Analysis (FMEA)

EasyChair Preprint 4210

Abstract

Fundamental problema in electricity distribution system are quality, continuity and availibility of electricity services for consumers. Failure Modes and Effect Analysis (FMEA) is one of the way to identify reliability index. From calculation of distribution system reliability in ULP Palopo Kota using FMEA method, Latuppa feeder shows results of SAIFI index : 8,91 failure/costumer.year and SAIDI index : 18,33 hour/costumer.year. Furthermore, Merdeka feeder shows result of SAIFI index : 1,916 failure/costumer.year and SAIDI index 3,478 hour/costumers.year. Frequencies of failure in the stream cause high number of failure in system compared with failure frequencies of distribution system equipment such as transformer, switch and CB, and so it affect SAIFI index number. On the other hand, SAIDI index number also got bigger following the long time of failure happens. To compensate for the high number of SAIFI and SAIDI index, fuse component and sectionalizer will be needed so that the system could perform reliably.

Keyphrases: FMEA, Reliability, distribution
