Abstract

Electrical energy is a very complex problem for every country in the world, as well as in Indonesia in particular, with the rapid progress of the country’s industry, of course, followed by an increase in the generation of electrical energy. While the current energy generation most often comes from fossil fuels, which are increasingly depleting, the energy supply will decrease and increase sales. Therefore, every country is competing to find other energy for electrical energy generation. Renewable energy is a green energy generator whose supply is abundant and inexhaustible. Solar power plants (PLTS) are one of the green energies developed by the Indonesian government to utilize energy derived from non-fossil fuels. To support this, it is necessary to study and research to be done using the DC-DC up/down converter is expected to obtain results that can be used as a reference in the development of solar power plants (PLTS). With a DC-DC up/down converter, the voltage stabilization produced by PLTS can be stabilized by a DC-DC converter from 9 volts DC to 11.5 volts for a minimum voltage. Above 12 volts to 18 volts, up to 12 volts can be stabilized.

Abstract

Sistem distribusi merupakan penyalur energi listrik yang berhubungan langsung dengan pelanggan yang harus dijaga kestabilan nya . Pada penelitian ini bertujuan menganalisisa perbaikan/menurunkan nilai SAIDI SAIFI terkait pemasangan fusesaver pada Penyulang H3 Gardu Induk Harapan Baru. Dalam penelitian ini dinilai berdasarkan dua indeks utama, yaitu System Average Interruption Duration Index (SAIDI) dan System Average Interruption Frequency Index (SAIFI). Data ini yang digunakan yaitu sebelum dan setelah pemasangan fusesaver. Hasil penelitian menunjukkan bahwa pemasangan fusesaver mampu memperbaiki/menurunkan SAIDI dari 2.122 jam/tahun menjadi 1.713 jam/tahun. Sementara nilai SAIFI menurun dari 3.315 kali/tahun menjadi 2.697 kali/tahun, menunjukkan kedua nilai tersebut telah memenuhi standar yang dianjurkan menurut SPLN 68-2:1986, dengan SAIDI di bawah batas maksimal 21 jam/tahun dan SAIFI di bawah 3.2 kali/tahun. Dengan itu pemasangan fusesaver berpengaruh dalam memperbaiki/menurunkan nilai SAIDI SAIFI pada sistem distribusi khusunya pada penyulang H3 Gardu Induk Harapan Baru
