Abstract

Energi baru terbarukan (EBT) merupakan salah satu program pemerintah yang bertujuan untuk menyediakan energi bersih untuk memenuhi kebutuhan energi dalam negeri. PT. Pertamina RU-IV Cilacap merupakan salah satu industri yang akan menerapkan sistem EBT dengan membangun pembangkit listrik tenaga surya (PLTS). Meninjau dari kondisi tersebut tugas akhir ini akan membahas mengenai studi kelayakan akibat penambahan PLTS 3 MW pada sistem kelistrikan di PT. Pertamina RU-IV Cilacap. Pada studi kelayakan pada suatu PLTS harus dilakukanya analisa pada hal- hal berikut, yaitu penentuan lokasi modul PV, sizing modul PV, aliran daya, hubung singkat, kestabilan transient, koordinasi proteksi dan analisis ekonomi. Penyelesaian permasalahan tersebut digunakan software ETAP dan PVsyst dalam membantu analisa dan simulasi. Berdasarkan hasil analisis bahwa penambahan PLTS 3 MW dapat mengurangi produksi listrik dari generator. Nilai tegangan pada bus 95.14 % hingga 104% dan untuk nilai cosphi 85% hingga 98.1%. Berdasarkan hasil simulaasi aliran daya kondisi sistem masih dalam kondisi baik. Perubahan nilai arus hubung singkat pasca penambahan PLTS relative kecil. Peralatan pengaman baru hanya terpasang pada bus yang menghubungkan PLTS dengan sistem eksisting. Kondisi sistem terhadap respon tegangan, frekuensi dan sudut rotor masih dalam kondisi baik karena dapat menjaga kestabilan sistem. Pemasangan PLTS di PT.Pertamina RU-IV dapat menghasilkan 3405 MWp, dengan biaya pembangkitan 0.14 US$ dan lama waktu kembali modal pada tahun ke-11 dengan masa angsuran 15 tahun.

Renewable energy is a government program that aims to provide clean energy to meet domestic energy needs. PT. Cilacap Pertamina RU-IV is one of the industries that will implement the renewable energy system by building solar power plants. Judging from these conditions this final project will discuss the feasibility study due to the addition of 3 MW solar power plants in the electricity system at PT. Pertamina RU-IV Cilacap. In a feasibility study on a solar power plant, it must be analyzed in the following matters, namely the determination of the location of PV modules, PV module sizing, power flow, short circuit, transient stability, protection coordination and economic analysis. ETAP and PVsyst software was used to solve this problem in helping analysis and simulation. The results of the simulation showed that the addition of 3 MW solar power plants could reduce electricity production from the generator. The value of the voltage on the bus is 95.14% to 104% and for cosphi values 85% to 98.1%. Based on the results of simulaasi the power flow of the system condition is still in good condition. Changes in the value of short-circuit current after addition of solar power plants are relatively small. New safety equipment is only installed on buses that connect solar power plants with existing systems. The condition of the system to the voltage response, frequency and angle of the rotor is still in good condition because it can maintain system stability. Installation of solar power plants at PT. Pertamina Pertamina RU-IV can produce 3405 MWp, with generation costs of 0.14 US $ and capital returns in the 11th year with a 15 year installment period.
