Abstract
Distributed new energy access to distribution network can realize the combination of solar energy,wind energy,tidal energy and other green clean energy with conventional electric energy,better meet the user's demand for electricity,improve the stability and continuity of power supply,and achieve the goal of energy saving,avoiding the waste of conventional electric energy resources.In order to ensure the safety of the combination of new energy and conventional electric energy,the technical situation of distributed new energy and the composition and function of relay protection in the distribution network was analyzed,the multiple impacts of distributed new energy access to the distribution network on the power supply system was pointed out,and the relay protection methods of distributed new energy access to the distribution network were proposed based on the guidance of power supply security,to ensure the safe combined application of new energy and conventional electric energy.
