The development of the impedance measured by distance relay during near-to-generator short circuit

This paper explains the possibility of implement of a model of a quadrilateral characteristic type of distance relay with the zones by using MATLAB / SIMULINK package. Sim Power System was used to present modeling of distance relay. The quadrilateral R-jX plain was created to show the trajectory of measured impedance using the distance relay. The relay identifiers the fault locations as expected. The impedance path reflects to the power system model under fault conditions. The goal of this paper is to describe the building and designing distance relay by using Simulink model, inside the modeling, impedance calculation, zone coordination were designed.
