Abstract

Pembangkit Listrik Tenaga Surya (PLTS) memiliki kerentanan tinggi terhadap sambaran petir karena konfigurasi sistem yang luas dan keterlibatan peralatan sensitif. Penelitian ini bertujuan merancang sistem proteksi petir eksternal dan internal pada PLTS di REIDI sesuai standar IEC 62305, serta mensimulasikan respons sistem terhadap fenomena Ground Potential Rise (GPR) menggunakan ATP Draw. Sistem proteksi eksternal dirancang menggunakan metode rolling sphere Level Proteksi I. Sistem pentanahan menggunakan elektroda vertikal dan konduktor BC Wire 50 mm², dengan resistansi tanah 4.34 Ω. Separation distance hanya terpenuhi pada konfigurasi Ground Mounted. Untuk Container dan Agrivoltaic, dilakukan mitigasi melalui equipotential bonding antara struktur logam, pentanahan peralatan, dan sistem petir, serta pemasangan SPD di sisi PV dan input DC inverter. Hasil simulasi menunjukkan GPR maksimum sebesar 12.7 kV tanpa proteksi. Dengan bonding, GPR turun rata-rata 19.03%. Penambahan SPD di sisi PV menurunkan GPR hingga 40.25%. Kombinasi bonding dan SPD di PV serta inverter menurunkan GPR maksimum menjadi 0.33 kV (82.60%). Rancangan ini membuktikan bahwa integrasi proteksi eksternal dan internal mampu meningkatkan keandalan sistem PLTS di REIDI, meskipun separation distance tidak seluruhnya terpenuhi.

Solar Power Plants are highly vulnerable to lightning strikes due to their extensive system configuration and the involvement of sensitive equipment. This study aims to design both external and internal lightning protection systems for the Soalr Power Plant at REIDI in accordance with IEC 62305 standards, and to simulate the system’s response to Ground Potential Rise (GPR) phenomena using ATP Draw. The external protection system is designed using the rolling sphere method with Protection Level I. The earthing system employs vertical electrodes and 50 mm² BC wire conductors, resulting in a measured soil resistance of 4.34 Ω. Separation distance is only maintained in the Ground Mounted configuration. For the Container and Agrivoltaic areas, mitigation is applied through equipotential bonding between metallic structures, equipment grounding, and the lightning protection system, along with the installation of SPDs at the PV side and DC inverter input. Simulation results show that without protection, the maximum GPR reaches 12.7 kV. With bonding, the average GPR decreases by 19.03%. Adding SPDs at the PV side further reduces GPR by 40.25%. The combination of bonding and SPDs at both the PV and inverter input yields the most effective protection, reducing maximum GPR to 0.33 kV (82.60%). This design demonstrates that the integration of external and internal lightning protection systems significantly enhances the reliability of the Solar Power Plant at REIDI, even when separation distance is not fully achieved.
