Therefore, theprotection of electrical equipment is essential and one of the devices performing the protection task iscalled the protection relay.Industrial plants and large consumers that possess a high variation in loads and variable generationresulting from the widespread implementation of distributed generation requires the adaptive operation ofrelays in protection systems to prevent undesired malfunctions.In this study, a novel fuzzy logic based adaptive relay coordination strategy with the advantages ofreduced computational load and fast computing for distribution networks is proposed. In order to evaluatethe performance of the developed relay coordination strategy, a real-world sample line for a ring-typedistribution network has been simulated in PSCAD/EMTDC environment. The performance of theproposed system is validated with simulation results for different case studies.eninfo:eu-repo/semantics/openAccessArticle158114942530335
