A centralized grid-connected photovoltaic(PV) station is a widely adopted method of neutral grounding using resistance. It requires that the fault can be quickly removed in the event of grounding faults. Therefore, the study of short circuit zero sequence current calculation of grid-connected PV station is of great significance. To this end, an engineering calculation method for zero-sequence current of grid-connected PV station with neutral grounding resistance is proposed. This method takes into account t...
