Modern practice is to adopt definite distance method of protection applied in 3 zones (steps). A number of distance relays are used in association with timing relays so that the power system is divided into a number of zones with varying tripping times associated with each. This protection relay configuration consists of three distinct stages: Instantaneous Overcurrent Protection (Stage I), Time-Limited Overcurrent Protection (Stage II), and Definite-Time Overcurrent Protection (Stage III). The protection relay's core functionality lies in its graded coordination. Protective relays and devices have been developed over 100 years ago to provide “lastline”of defense for the electrical systems. Instantaneous Overcurrent Protection (Stage 1): No intentional time delay. This document provides recommendations, background and philosophy on relay protection that is not available in M07. In this paper, on the basis of the features of the relay protection in the power line, thorough research and the analysis of relay protection both at home and abroad, with the aid of MATLAB/Simulink to build simulation model, Using PSB module to construct a three-stage over-current protection's.
