This article explores the current trends, innovations, and market insights surrounding relay protection, focusing on tools like the secondary injection test set, three-phase relay test set, and single-phase relay test set. 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. Relay protection systems are essential in maintaining the safety and reliability of modern electrical grids. The new generation of intelligent substations has achieved online monitoring functions for secondary equipment, making some state variables of relay protection equipment become observable indicators. To achieve information sharing and interoperability among intelligent electrical equipment in intelligent substations, the author proposes research on relay protection and security technology for the expansion project of intelligent substations.
