Fault Characteristics Analysis and Line Protection Design Within a Large-Scale Photovoltaic Power Plant.

Centralized photovoltaic (PV) systems have different fault characteristics from distributed PV systems due to the different system structures and controls. This makes the fault analysis and protection methods used in distribution networks with distributed PV not suitable for a centralized PV power plant. Therefore, a consolidated expression for the fault current within a PV power plant under diffe...
