Analysis of the Impact of Grid Connection of Photovoltaic New Energy on Relay Protection
The scale of photovoltaic power station construction in China has expanded,and more photo-voltaic power stations are connected to the grid.Due to the different flow and distribution of short-circuit current from the original distribution network,it has an impact on relay protection and reduces the stability of distribution network operation.For this purpose,the article briefly elaborates on the characteristics of pho-tovoltaic new energy grid connected current assistance and current diversion.Starting from the two aspects of photovoltaic grid connected connection location and grid connected capacity,the impact of photovoltaic new energy grid connected on relay protection is analyzed,and an improvement plan for relay protection is pro-posed,in order to provide reference for relevant workers.
