Abstract: One of the most important domains of concern in electrical power system engineering is the protection and reliability of the system. Nowadays, it is quit evident that the implementation of an intelligent algorithm is paramount in providing protection to the equipment of a substation including auxiliary components using relays and breakers as well. Most of the research have been based on single load connected to a single feeder line. Many different algorithm have been followed to present various intelligent relaying schemes on over current protection, transmission line protection, transformer protection, distance protection to name some. These are based on numerous distinguished algorithm like Digital Signal Processing, Genetic Algorithm, Artificial Neural Network, Fuzzy Algorithm and many more. The aim of this paper is to review articles on Fuzzy based intelligent relaying schemes appearing in scientific journals. We have discussed individual problem statements along with the respective solutions are proposed by the investigator(s) too. Further, we have summarized the present scenario of protection sector of power and energy department along with it s unsolved problem issues. Finally, we identified few of the research gaps to clarify and to suggest future research opportunities.
