Ferroresonance phenomenon in PV system at LV side of three phase power transformer using of PSCAD simulation

Abstract

Nowadays, most Photovoltaic installations are grid connected system. From distribution system point of view, the main point and concern related to PV grid-connected are overvoltage or overcurrent in the distribution network. This paper describes the simulation study which focuses on ferroresonance phenomenon of PV system on lower side of distribution transformer. PSCAD program is selected to simulate the ferroresonance phenomenon in this study. The example of process that creates ferroresonance by the part of PV system and ferroresonance effect will be fully described in detail.
