Abstract

Saat ini pasokan energi listrik masih belum terpenuhi pada sebagian daerah dikarenakan semakin menipisnya sumber energi konvensional dan energi fosil. Energi alternatif yang ideal adalah energi terbarukan. Tempat Pembuangan Akhir (TPA) Gampong Jawa Banda Aceh memiliki potensi pembangkit listrik tenaga biomasa (PLTBm) dikarenakan memiliki banyak sampah dengan rata-rata produksi 250 ton per hari. Berdasarkan titik koordinat TPA Gampong Jawa, Banda Aceh menggunakan simulasi HOMER diperoleh nilai radiasi matahari (Photovoltaic) sebesar 4,12 kWh/m^2/hari. Tujuan dari penilitian ini adalah memperoleh jumlah energi potensi biomassa dan photovoltaic serta model yang optimal untuk sistem pembangkit listrik hibrida di TPA Gampong Jawa. Dari hasil penilitian ini potensi daya listrik dari pembangkit biomassa di TPA Gampong Jawa, yaitu 2000 kW yang dapat menghasilkan energi listrik dalam satu tahun yaitu 12.641.232 kWh. Ada tiga skenario yang digunakan untuk mensimulasikan model Pembangkit Tenaga Listrik Hibrid (PLTH). Model yang paling optimal adalah skenario 3 dengan nilai Net Present Cost (NPC) dan Cost of Energy (COE) yang terkecil. Nilai Net Present Cost (NPC) dan COE masing-masing adalah $ 42.698.527 dan $ 0,2614 dimana biomassa dan photovoltaic menghasilkan energi listrik masing-masing 11.753.607 kWh per tahun dan 1.248.080 kWh per tahun, generic 1 kWh Lead Acid 300 unit dan converter 720 kW.

Abstract

Short-circuit faults in power distribution systems generate excessive fault currents that can damage electrical equipment and reduce system reliability. One practical method for limiting fault current is the installation of a series reactor or current limiting reactor (CLR). This study analyzes short-circuit current characteristics in the 20 kV Ulee Kareng distribution feeder in Banda Aceh and evaluates the effectiveness of a series reactor in reducing fault current levels. The analysis was performed using ETAP 19.0.1 simulation software based on the IEC 60909 standard. Four fault types were investigated: three-phase, single line-to-ground, line-to-line, and double line-to-ground faults. The simulation results show that the maximum three-phase short-circuit current before reactor installation was 4.066 kA at bus LBU 01-00, while the minimum value was 2.732 kA at bus LBU 42-00. A series reactor with a reactance value of 3.12 Ω was designed to achieve approximately 50% current reduction. After installation, the three-phase short-circuit current at bus LBU 01-00 decreased to 2.103 kA, corresponding to a 48% reduction. The results confirm that the series reactor effectively reduces fault current levels and improves protection system performance without replacing existing circuit breakers. The novelty of this study lies in the evaluation of series reactor performance for all fault types in the actual 20 kV Ulee Kareng distribution feeder using IEC 60909-based ETAP simulations under real operating conditions
