Abstract
It has always been of great importance in the electrical power system to educate an algorithm on the digital relaying, but it is difficult to educate an algorithm of a digital distance relay on power system because of exclusiveness of the relaying algorithm on power system. Therefore, we need a digital distance relay simulator, which can simulate the algorithm of the digital relaying on transmission line. In this Paper, we extract fundamental components using digital signal processing from data which are a variety of the simulated faults by EMTP. Then this simulator represents instantaneous values, ms values and symmetrical components that are calculated by fundamental components of voltages and currents. The Simulator also represents the zones of a digital distance relay and the locus of an impedance using GUI. Consequently, the developed simulator is particularly useful for understanding of the fundamental concepts of a distance relaying algorithm from a power system engineer points of view.
