Adaptive Distance Protection Strategy for Distributed Photovoltaic Grid Connection
In order to solve the protection problem brought by photovoltaic grid-connected to the power grid,a protection model with photovoltaic system based on adaptive distance protection is proposed.The calculation of the distance protection parameters of the system containing photovoltaic power plants is demonstrated,and the validity of the model proposed in this paper is verified by simulation analysis.It shows that under the mechanism studied in this paper,the system is not affected by photovoltaic parame-ters and can effectively solve the problem that the transition resistance has a great influence on the distance protection and improves the robustness of the protection system.
