Transmission Line Analysis using PowerX.This paper describes a software implementation of a Transmission Line Analysis moduleto an existing software application, named PowerX, which is used for educationalinstruction in the courses EENG ***: Energy Systems and EENG ***: Power SystemsAnalysis at * * University. PowerX is a windows-based software application, writtenentirely in C#, that was originally developed under an internal grant from *** to doresearch in the area of Synchrophasors for the Power Grid. Over time, more and morefunctionality was added to PowerX and eventually it started being used in classes likeEENG *** and EENG *** in order to give the students a better physical feel for realisticnumbers when doing numerical computations as well as displaying graphicalrepresentation of typical power system problems. The Transmission Line Analysismodule developed for PowerX provides functionality for computing the resistance,inductance and capacitance of transmission lines for a variety of different lineparameters. Given these quantities, PowerX provides the ability to analyze a transmissionline using either the small, medium or long length mathematical model and subsequentlycompute power flow, power factor, efficiency and voltage regulation of a giventransmission line. A statistical assessment of the student’s grades for two differentquarters is also presented. One quarter the students did not use PowerX and the otherquarter the students did use PowerX. 1
