Abstract

Intelligent substations play a crucial role in modern power systems. However, the existing relay protection configurations face challenges such as insufficient fault diagnosis accuracy, communication delays, and vulnerable cybersecurity, especially in the context of complex network structures and the integration of distributed power sources. To address these issues, optimization strategies based on big data analytics, artificial intelligence, and the Internet of Things have been proposed and implemented. These strategies have significantly improved the performance of relay protection systems by enhancing fault diagnosis capabilities, improving system reliability, and optimizing maintenance management. Looking ahead, with the continuous development of smart grids, relay protection systems need to further integrate innovative technologies to meet new operational requirements and provide a more robust safeguard for the safe and efficient operation of power grids.
