Abstract :
This paper presents a standard pilot phase comparison protective relaying scheme for transmission lines. It offers excellent sensitivity, very fast tripping, immunity to power swings, effective protection for long or short lines, and reduced need for setting calculations and settings maintenance. The performance is superior to that of pilot distance or directional comparison schemes. The proposed scheme meets the technical and management demands for protective relaying satisfying more stringent system security requirements.
