Research on Relay Protection Strategy of Distributed Photovoltaic Power Station Connected to Power Grid
With the increasing attention to renewable energy in the world,distributed photovoltaic power station as an important form of clean energy has been developed rapidly.This paper delves into the relay protection strategy of distributed photovoltaic power station connected to power grid;in view of the protection complexity and challenges for the power grid after the distributed photovoltaic power station is connected to the power grid,a relay protection strategy based on fault characteristic analysis and real-time data processing is proposed,and the corresponding protection algorithm and configuration scheme are designed.This strategy can effectively improve the security and stability of the power grid,and provide technical support for the grid-connected operation of distributed photovoltaic power stations.
