Abstract：With the integration of distributed generation (DG) into distribution network, the topological structureand power flow distribution of distribution network change. The traditional relay protection configuration of distribution network is no longer suitable for distribution network with DG. In order to ensure the power supply reliability of power system and give full play to the advantages of distributed energy, it is necessary to study the protection scheme of distribution network with distributed generation. On the basis of expounding the principle of three-stage current protection in distribution network, this paper discusses in detail the specific impact of different access capacity and access location of distributed generation on the current protection at different fault points of distribution network. Combined with the cutting-edge research results at home and abroad, the main solutions are discussed, the principles and characteristics of different protection schemes are classified, and their advantages and disadvantages are explained.. This paper has a certain reference value for the distribution network protection with distributed generation.
