Abstract：With the new energy sources are connected to the distribution system, the network structure of the traditional radiation distribution system with single source has been fundamentally changed. In addition, the complicated fault current characteristics and diversified power generation mode of the new energy sources brings many new problems and challenges to the traditional relaying protection and setting calculation on the distribution system. In this paper, the influence of the new energy sources for the current protection of the distribution network is analyzed. Based on this, the forward, reverse and isolated island reverse fault trip matrix are established based on regional information. The influence of “bus” fault, fault of line and DFIG crowbar protection are also considered. Then, the new principle of networked protection in the distribution system with new energy sources is proposed. Finally, simulation examples verify the theoretical analysis results.
