In modern protection system the key challenge is the trade-off between the security demand no false tripping the speed of operations and the dependability requirements. To meet this challenge properly the application of a novel Artificial Intelligence AI method using fuzzy logic in power system protection has been proposed in this paper along with the simulated data. The examined technique based on fuzzy logic and value estimation to control the protection action of the protective relay was intended to improve the performance of a conventional protective relay control for human safety and system reliability with the use of a fuzzy logic controller. The difference between estimated and sampled values was used to form the rule base. Proposed relay architecture was used as a detector and was developed to predict faults and to protect particular sections of a designed prototype radial power system at an early stage. Performance analysis of the developed model is simulated using Simulink and found satisfactory output.
