Files in COMTRADE format are possible to generate after ATP simulation. These files can be used to calibrate real relays. Also, the performance of relay algorithms with real oscillography events is possible to assess by using the ATP option for POSTPROCESS PLOT FILE (PPF). The main purpose of the work is to develop a tool to allow the analysis of diverse fault cases and to perform coordination studies, as well as, to allow the analysis of the relay's performance in the face of a real event. © 2011 IEEE.146-151engANSI CATPCOMTRADEforeign modelsMODELSnumerical distance relaypower systemsprotection systemsCOMTRADE formatDistance protectionDistance relayInteractive simulationsOscillographyPost processProtection systemsSimulation environmentAdenosinetriphosphateC (programming language)Circuit simulationElectronic data interchangeModelsStandby power systemsComputer simulationTrabalho apresentado em evento10.1109/EPEC.2011.6070185Acesso aberto2-s2.0-829552406890614021283361265
