Abstract

Intisari Sistem PLTS yang terhubung ke jaringan tanpa transformator merasakan arus bocor akibat adanya kapasitansi parasitik pada panel surya yang diketanahkan dan hubungan galvanis antara sumber DC dan jaringan. Arus bocor berbahaya bagi keselamatan manusia yang menyentuh panel surya. Penelitian ini menghitung arus bocor melalui simulasi menggunakan Matlab. Rangkaian simulasi terdiri dari sumber DC PLTS, inverter satu fasa, sumber AC jaringan, filter dan kapasitansi parasitik. Kapasitansi Parasitik dimodelkan dengan sebuah kapasitor tunggal. Kondisi panel basah atau kering memberikan nilai kapasitansi yang berbeda. Hasil simulasi menunjukkan bahwa kondisi panel basah menghasilkan arus bocor sepuluh kali lebih tinggi dari kondisi panel kering. Arus bocor pada kedua kondisi masih dibawah batas maksimum standar keselamatan mengacu pada DIN VDE 0126-1-1.Kata kunci arus bocor, PLTS, kapasitansi parasit, arus common mode, inverter.Abstract PV system on grid transformerless experiences leakage current due to parasitic capacitance on grounded-PV panel and a galvanic connection between the grid and the dc source. Leakage current is harmful for human who touch the PV panel. This research calculates the leakage current via simulation using Matlab. Simulation circuit consists of DC source as PV system, one phase inverter, grid AC source, filter and parasitic capacitance. A single capacitor is used to model parasitic capacitance. Wet and dry condition of PV panel generate a different capacitance. The simulation results show wet PV panel produce a leakage current ten times higher than that in dry PV panel. The leakage curent either in wet and drycondition are below maximum limit of DIN VDE 0126-1-1 safety standard.Keywords leakage current, PV system, parasitic capacitance, common mode current, inverter.
