N2 - Due to the fact that fault characteristics of the distribution network with photovoltaic (PV) integration are quite different from those in the traditional distribution network, conventional overcurrent protections have encountered new challenges. In this paper, a novel inverse-time undervoltage protection principle is proposed, which uses voltage drop to detect the fault and current to determine the faulty line. This scheme is not impacted by the system operation mode, which causes a sensitive and fast responsed relaying. In addition, it requires no communication resulting in a simple implementation. PSCAD based simulations demonstrate the rationality and effectiveness of this proposed protection scheme.
