Comparative Study of TACS/DBM and MODELS of ATP-EMTP Applied to Power Systems Computer Simulation

The ATP-EMTP has become a reference program for electromagnetic transients computer simulations. Due to the contributions of its officer's users groups spread around the world, several improvements were made and additional resources have been developed to facilitate and expand its application. Tools, like ATPDraw, PlotXY, TACS, DBM and MODELS, can drive and enable excelent research studies which may result in internationally renowned scientific papers in the field of Electrical Systems. It is then presented in this paper an additional user guide for these tools with procedures tested in practice and often not covered by official manuals, combined with an analysis of the use of TACS/DBM and MODELS through the computational implementation of a speed governor. The purpose is to identify the potentiality as well as the advantages and disadvantages of TACS/DBM and MODELS. Thus, any user interested in the correct and effective use of these tools may determine the one most suitable to accomplish the computer simulation.
