Evaluation of Ground Currents in a PV System with High Frequency Modeling

Fabio Viola, M.C. Di Piazza, G. Vitale

Abstract


In this work a high frequency model of a photovoltaic (PV) plant is identified and implemented aiming to investigate the common mode (CM) currents circulating through the ground connections of the plant. From the identification of the impedance obtained by frequency response of photovoltaic module and by a suitable of the power conversion unit, an equivalent high frequency circuit representation has been developed. The lumped parameters circuit model is implemented in PSpice environment to obtain   the CM leakage currents.

Keywords
