Home / What is intelligent relay protection
In relay protection, AI and ML techniques are gaining traction as tools to improve the reliability and efficiency of protective schemes within smart grids AI environments. Relay protection is essential in an electrical network to detect and isolate faulty components, preventing. the relay instantly sends a trip command to the vacuum circuit breaker (VCB) inside the switchgear. Artificial Intelligence (AI) and Machine Learning (ML) are two powerful technologies that have been rapidly advancing in various industries, including electrical power systems. This paper introduces each of the system characteristics that should be considered for protection operation within Smart Grid, and the evaluation methods that were applied under both normal and faulted conditions.
They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. The selection and applications of protective relays and their associated
