Optimization and Reliability Analysis Based on Saidi, Saifi Values on 20KV Distribution System Channels at PT. PLN ULP Labuhan Haji
Keywords:
Reliability, SAIDI, SAIFI, CAIDIAbstract
The level of reliability in distributing electrical energy to customers is very important. A system and a fast method are needed to produce reliability index values. This study uses a quantitative research method with the RIA (Reliability Index Assessment) method aimed at calculating the reliability index of the System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI) of the 20kV distribution system at PT. PLN (Persero) ULP Labuhan Haji. Based on the results of the study, the results were obtained Based on the calculation of the SAIDI, SAIFI and CAIDI values in 2023 PT. PLN ULP Labuhan Haji, the SAIDI value was 5.46 hours/customer/year and the SAIFI value was 8.60 times/customer/year while the CAIDI value was 7.15 Based on the provisions of SPLN 68-2: 1986 for SAIFI it has not met the Standard so that improvements need to be made, while the SAIDI value has met the standards and provisions of SPLN. Referring to the provisions of IEEE std 1366-2003, the electricity distribution system of PT. PLN ULP Labuhan Haji cannot yet be categorized as reliable.
