In this paper,by using Excel,PSCAD/EMTDC and ATP/EMTP program,sequence parameters of a 110 kV double circuit transmission lines are calculated and the accuracy of the calculation results are examined in detail. Furthermore, the author of the paper proposes a new line parameter calcula-tion method based on relay calculation program. Based on graphical modeling and with corresponding database established and data management capabilities equipped, the interface program can serve as an important tool for protection setting calculation. Finally,it can play a very important role in imp-roving the efficiency and accuracy of relay calculation work.
