Abstract

Keandalan sistem distribusi merupakan tingkat keberhasilan kinerja suatu sistem distribusi dalam pelayanan penyediaan tenaga listrik dari sistem ke konsumen. Sebagian besar pemadaman dalam sistem tenaga listrik disebabkan karena permasalahan yang mendasar yaitu pada distribusi daya listrik adalah terletak pada mutu, kontinuitas dan ketersediaan pelayanan daya listrik ke pelanggan. Tugas akhir ini dibuat dengan tujuan mengevaluasi keandalan sistem distribusi PT. PLN (Persero) Surabaya Utara sehinggga dapat digunakan sebagai rekomendasi untuk meningkatkan keandalan pada sistem tersebut. Keandalan sistem yang dianalisis adalah keandalan jaringan distribusi Surabaya dengan 12 GI menggunakan metode RIA (Reliability Index Assessment) dimana sistem diasumsikan berada pada dua kondisi yaitu kondisi perfect switching dan imperfect switching. Dari hasil perbandingan perhitungan nilai SAIDI, SAIFI, MAIFI, dan CAIDI pada terlihat bahwa nilai SAIDI, SAIFI, dan CAIDI pada kondisi imperfect switching lebih besar daripada saat kondisi perfect switching. Hal ini disebabkan karena pada kondisi imperfect switching, peralatan seperti circuit breaker dan trafo juga ikut berkontribusi dalam perhitungan yang mengakibatkan nilai SAIDI, SAIFI, dan CAIDI semakin besar. Namun nilai MAIFI untuk sistem pada kedua kondisi sama karena peralatan circuit breaker tidak memberikan kontribusi gangguan sesaat dalam perhitungan nilai MAIFI. Jumlah komponen peralatan distribusi juga ikut mempengaruhi besar/kecilnya indeks keandalan tersebut. ================================================================================================================== The reliability of the distribution system is the success rate performance of a distribution system in the service of electricity supply from the system to the consumer. Most of the outages in the power system caused by a fundamental problem, namely the distribution of electrical power is situated on the quality, continuity and availability of electric power service to customers. The final task was created with the purpose of evaluating the reliability of the distribution system PT. PLN (Persero) North Surabaya so as it can be used as a recommendation to increase the reliability of the system. The reliability of the system being analyzed is the reliability of the distribution network with 12 GI Surabaya using RIA (Reliability Index Assessment) where the system is assumed to be in perfect condition two conditions, namely switching and switching imperfect. From the comparison calculation of SAIDI, SAIFI, MAIFI, and CAIDI to be seen that the value of SAIDI, SAIFI, and CAIDI in imperfect conditions is greater than the switching current switching perfect condition. This is due to the imperfect switching condition, equipment such as circuit breakers and transformers also contribute to the calculation of the resulting value of SAIDI, SAIFI, and CAIDI greater. However MAIFI value to the system in both the same conditions as the equipment circuit breaker does not contribute to momentary interruption in the calculation of the value of MAIFI. Distribution equipment component count also affects the large/small the reliability index.
