Abstract
Pembangkit listrik tenaga surya menjadi salah satu penghasil energi listrik yang paling banyak digunakan dengan memanfaatkan energi terbarukan yaitu matahari. PV farm umumnya terletak di area yang luas dan terbuka yang tidak terlepas dari ancaman sambaran petir. Sambaran petir menghasilkan medan elektromagnetik yang kuat dan induksi tegangan berlebih yang dapat menyebabkan komponen PV seperti inverter, kabel DC, dan frame PV mengalami gangguan. Sistem proteksi petir dirancang untuk memenuhi tingkat proteksi petir level III, dengan menggunakan metode sudut proteksi, digunakan terminasi udara dengan tinggi 3 meter yang terletak di 8 titik pada area PV farm. Tujuan dari penelitian ini dilakukan perhitungan tegangan berlebih akibat induksi sambaran petir tak langsung dan menganalisis sambaran petir di titik yang berbeda. Penelitian ini menganalisis dampak sambaran petir tak langsung pada kabel output pada PV modul string dan kabel sebelum inverter. Pemodelan PV farm dimodelkan dan disimulasikan menggunakan software ATPDraw. Pemodelan sistem proteksi petir di desain dalam langkah mengurangi induksi elektromagnetik akibat sambaran petir tak langsung serta melindungi PV modul string dan inverter. Hasil dari penelitian ini menunjukkan bahwa tegangan berlebih terbesar berada pada kabel output PV modul string yang jaraknya terdekat dengan sambaran petir tak langsung terhadap penangkal petir. Penurunan terbesar rata-rata tegangan berlebih dalam rangkaian PV farm setelah ditambahkan SPD sebesar 96%.

Solar Solar power plants are one of the most widely used producers of electrical energy by utilizing renewable energy, namely the sun. PV farms are generally located in large, open areas that are not free from the threat of lightning strikes. Lightning strikes produce strong
electromagnetic fields and induced excessive voltage which can cause PV components such as inverters, DC cables and PV frames to experience interference. The lightning protection system is designed to meet level III lightning protection level, using the corner protection method, using air terminations with a height of 3 meters located at 8 points in the PV farm area. The aim of this research is to calculate excess voltage due to induction of indirect lightning strikes and analyze lightning strikes at different points. This research analyzes the impact of indirect
lightning strikes on the output cables in PV module strings and cables before the inverter. The PV farm was modeled and simulated using ATPDraw software. The lightning protection system modeling is designed in steps to reduce electromagnetic induction due to indirect lightning strikes and protect the PV string module and inverter. The results of this research show that the largest overvoltage is in the PV output cable of the string module which is closest to the indirect lightning strike on the lightning rod. The largest reduction in average overvoltage in the PV farm circuit after adding SPD was 96%.
