Farraz, Dayrry Yozza and Ir. Teguh Utomo, M.T. and Ir. Wijono, M.T. Ph.D. (2024) Analisis Keandalan Sistem Distribusi 20 kV Penyulang Bunul PT. PLN ULP Malang Kota Menggunakan Metode RIA (Reliability Index Assessment). Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini membahas tentang analisis keandalan sistem distribusi 20 kV Penyulang Bunul PT. PLN ULP Malang Kota. Beberapa indeks yang digunakan untuk mengukur tingkat keandalan sistem distribusi adalah SAIFI (System Average Interruption Frequency Index), SAIDI (System Average Interruption Duration Index), dan CAIDI (Customer Average Interruption Duration Index). Tujuan dari penelitian ini adalah untuk mendapatkan nilai indeks keandalan (SAIDI, SAIFI, CAIDI) Penyulang Bunul PT. PLN ULP Malang Kota dengan metode RIA (Reliability Index Assessment) dan simulasi single line diagram pada ETAP serta membandingkan nilai indeks keandalan tersebut dengan standar SPLN 59 tahun 1985. Metode yang digunakan adalah metode RIA dan simulasi Software ETAP 19.0.1. Berdasarkan hasil perhitungan metode RIA, nilai laju kegagalan dan ketidaktersediaan masing-masing bernilai 2,7120210 gangguan/tahun dan 12,3712701 jam/tahun, Sementara SAIFI sebesar 1,6761635 gangguan/tahun, SAIDI 9,2354936 jam/tahun, dan CAIDI 5,5099002 jam/gangguan. Hasil simulasi indeks keandalan pada ETAP menunjukkan nilai SAIFI sebesar 2,4640 gangguan/tahun, SAIDI sebesar 5,7485 jam/tahun, dan CAIDI sebesar 2,333 jam/gangguan. Berdasarkan hasil yang telah didapatkan, persentase selisih nilai indeks keandalan metode RIA dan ETAP pada nilai SAIFI, SAIDI, CAIDI berturut-turut adalah 47%, 38%, 58%. Perbedaan nilai tersebut disebabkan oleh kondisi imperfect switching pada perhitungan yang melibatkan komponen selain saluran distribusi. Dengan seluruh nilai indeks keandalan dari metode RIA dan simulasi ETAP Penyulang Bunul PT. PLN ULP Malang Kota lebih kecil dari nilai pada SPLN 59 tahun 1985, sistem distribusi Penyulang Bunul dapat dikatakan handal.
English Abstract
This research discusses the reliability analysis of the 20 kV distribution system of Bunul Feeder at PT. PLN ULP Malang Kota. Several indices used to measure the reliability level of the distribution system are SAIFI (System Average Interruption Frequency Index), SAIDI (System Average Interruption Duration Index), and CAIDI (Customer Average Interruption Duration Index). The objective of this research is to obtain the reliability index values (SAIDI, SAIFI, CAIDI) for the Bunul Feeder at PT. PLN ULP Malang Kota using the Reliability Index Assessment (RIA) method and single line diagram simulation on ETAP, as well as comparing these reliability index values with the SPLN 59 standard from 1985. The methods employed include the RIA method and ETAP 19.0.1 simulation software. Based on the RIA method calculations, the failure rate and unavailability values are 2.7120210 interruptions/year and 12.3712701 hours/year, respectively. Meanwhile, SAIFI is 1.6761635 interruptions/year, SAIDI is 9.2354936 hours/year, and CAIDI is 5.5099002 hours/interruption. The simulation results for the reliability indices in ETAP show SAIFI, SAIDI, and CAIDI values of 2.4640 interruptions/year, 5.7485 hours/year, and 2.333 hours/interruption, respectively. Based on the results obtained, the percentage differences in the reliability index values of the RIA and ETAP methods for SAIFI, SAIDI, CAIDI respectively are 47%, 38%, 58%. The differences in values are caused by imperfect switching conditions in calculations involving components other than distribution channels. With all reliability index values from the RIA method and ETAP simulation for the Bunul Feeder of PT. PLN ULP Malang Kota being smaller than the values in SPLN 59 of 1985, the distribution system of the Bunul Feeder can be considered reliable.
