Impact of Grid Integration of Photovoltaic Power Generation on Distribution Network Current and Relay Protection
In recent years,with the social and economic development,China's demand for electric power energy is increasing.In order to further stabilize the development of electric power,photovoltaic power generation grid-connected has been developed.This kind of technology is widely used,with low construction cost and low difficulty of grid connection,which has certain application advantages.However,grid-connected photovoltaic power generation will have a certain impact on the planning and design of traditional power grids,current distribution and relay protection.In general,the faults occurring in the distribution network containing PV power have complexity,so that the distribution network relay protection cannot meet the protection requirements.Therefore,in the process of grid-connected PV power generation,it is necessary to reevaluate the distribution network relay protection to reduce the probability of faults in the process of grid-connected PV power generation.The article mainly analyzes the impact of PV power grid connection on distribution network relay protection,hoping to provide reference for PV power generation.
