Abstract
Penelitian ini menganalisis gangguan hubung singkat tiga fasa pada sistem pembangkit listrik hybrid on-grid tenaga surya. Metode yang digunakan mencakup pemodelan sistem, analisis serta perhitungan arus dan waktu terjadinya gangguan hubung singkat, serta perhitungan tambahan daya reaktif untuk mengatasi gangguan tersebut. Hasil perhitungan menunjukkan bahwa irradiance tertinggi terjadi pada bulan September dengan nilai rata-rata sebesar 900,16 W/m² selama periode 2020 hingga 2024. Berdasarkan data tersebut, dipilih panel surya dengan total daya sebesar 2.006.590 W, yang disusun dalam konfigurasi 38 seri dan 118 string paralel, dengan total 4484 unit panel. Output sistem menghasilkan tegangan 1500 V dan arus 1.320,42 A, yang disesuaikan dengan inverter Sunny Central 2500-EV dan trafo step-down. Analisis gangguan hubung singkat menunjukkan arus tertinggi pada titik 1 sebesar 1189,551 A dan titik 5 sebesar 1337,852 A, dengan penurunan tegangan sebesar 39,38% pada titik 1 dan 16% pada titik 5. Untuk mempertahankan kestabilan tegangan pada kedua titik tersebut, kapasitor dengan nilai 414.357,3552 microfarad diinjeksikan pada titik 1 dan 638.417,63 microfarad pada titik 5.

This study analyzes three-phase short circuit disturbances in a hybrid on-grid solar power generation system. The research employs system modeling, analysis, and calculation of the current and duration of short circuit events, as well as the computation of reactive power injection to mitigate the effects of these disturbances. The results indicate that the highest irradiance occurs in September, with an average value of 900.16 W/m² over the period from 2020 to 2024. Based on this data, solar panels with a total power capacity of 2,006,590 W were selected, configured in 38 series and 118 parallel strings, totaling 4,484 panels. The system's output yields a voltage of 1500 V and a current of 1,320.42 A, which are adapted to the Sunny Central 2500-EV inverter and a step-down transformer. The short circuit analysis revealed the highest current at point 1 (1189.551 A) and point 5 (1337.852 A), with voltage drops of 39.38% and 16%, respectively. To maintain voltage stability at these points, capacitors of 414,357.3552 microfarads and 638,417.63 microfarads were injected at points 1 and 5, respectively.
