An interactive software of distance relaying for analysis of electrical events and educational use

This article presents an interactive software application to analyze and validate the operation of distance relays and its application for educational use. The design stages and theoretical fundamentals of distance relays are described and the proposed application has been structured to evaluate various design alternatives that include signal processing and different tripping characteristics. The software allows for the evaluation and analysis of distance relay operation with real time or simulated events in several commercial and academic electrical programs. Several examples are presented to illustrate the capabilities of this graphical software tool.

► The proposed software is to evaluate the distance relay under dynamic conditions.
► The exploration and analysis of a wide spectrum of events is possible.
► The effect of FACTS, wind turbines, and fault limiters can be evaluated.
► The computational tool proposed offers an educational alternative.
