The traditional power system relay protection system can provide protection for the power system to a certain extent, but it has many limitations, such as insufficient comprehensive monitoring ability for complex systems and weak accurate judgment ability. Protective relaying is the backbone of fault detection and system isolation in As transmission systems grow increasingly complex with integration of renewables and smart technologies, the design, configuration, and application of protective relays have become more critical than ever. It covers the protection methods for generators, transformers, buses, and transmission lines using various relay types to detect and isolate faults efficiently.
