These countermeasures include protection logic and settings optimization, fast fault detection technology application, adaptive protection strategy application, and enhancing communication and data processing systems. By taking a series of countermeasures, the paper explored the influence of new energy connection on traditional relay protection systems in response to the occurrence of the above phenomenon. An auxiliary relay rarely attracts. In this paper, the impact of distributed photovoltaic power generation on the low-voltage power grid during the grid connection is analyzed, and related countermeasures for relay protection are proposed. This paper examines the effects of electricity quality on the power grid and suggests. The research shows that the performance and reliability of relay protection device in transient process can be effectively improved by optimizing hardware design, introducing intelligent algorithm and improving self-healing ability, so as to ensure the safe and stable operation of power system. able sources such as wind and solar. These clean energy sources, connected through inverters and flexible transmission systems, are transforming traditional grids based on synchronous generators into more flexibl cant challenges to system stability. This paper presents design and implementation of a SSO relay model that can effectively extract.
