Abstract

Saat ini, tingkat keandalan dari suatu sistem distribusi adalah penting guna menjamin kontinuitas supply tenaga listrik kepada konsumen. Karena itu, disadari pentingnya otomatisasi sistem distribusi, yang salah satunya dapat dicapai dengan menggunakan sectionalizer. Tugas Akhir ini dibuat dengan tujuan menghitung indeks keandalan dari sistem distribusi 20 kV Rayon Lumajang. Metode yang digunakan adalah FMEA (Failure Mode and Effect Analysis), di mana indeks kegagalan dari setiap peralatan utama sistem distribusi diperhitungkan dalam mencari indeks keandalan sistem secara menyeluruh. Sejumlah studi kasus dilakukan guna melihat pengaruh dari jumlah serta lokasi penempatan sectionalizer di sepanjang jaringan terhadap indeks keandalan sistem. Pada akhirnya, solusi optimal akan memberikan nilai indeks keandalan sistem distribusi yang terbaik. Berdasarkan hasil analisa, dengan penambahan fuse pada penyulang sukodono dapat menaikkan Indeks Keandalan SAIFI yang semula bernilai 6.6088 menjadi bernilai 5.4176, lalu dengan adanya penambahan sectionalizer pada penyulang sukodono maka dapat menaikkan indeks keandalan SAIDI yang awalnya bernilai 7.6737 menjadi bernilai 6.4431. ======================================================================================================================== Nowadays, the reliability level of a distribution system is important to ensure the continuity of supply power to the consumer. As such the importance of automated system distribution is realized, one of which, could be achieved by using sectionalizer. The objective of this final project is to count the reliability indices of 20 kV Lumajang system distribution. The method engaged is FMEA (Failure Modes and Effects Analysis), where the failure rate of each main distribution system utility is accounted for to find the reliability indices system overall. A number of case study are carried out for the purpose of finding the influence of number as well as location of sectionalizer along the network to the system reliability indices. Finally, the optimum location will give the best distribution system reliability indices. Based on the analysis, with the addition of fuse in the Sukodono feeder can raise Reliability Index SAIFI which was originally worth 6.6088 becomes worth 5.4176, then with the addition of sectionalizer in the Sukodono feeder it can raise the reliability index SAIDI originally worth 7.6737 became worth 6.4431.
