Assessing the real-time performance of the frequency-dependent line model on eMEGAsim simulator

The aim of this paper is to describe a general procedure for incorporating new realistic models of power system components in modern EMTP-based real-time simulators. For doing this, a comprehensive description of the frequency-dependent transmission line model FD-Line is first presented. Then, it is described the implementation of this line model in Simulink environment for running off-line simulations of electromagnetic transients. This implementation allows the interaction with the Power System Blockset library and also, the real-time simulations in the PC-based real-time simulator eMEGAsim. Finally, several simulation cases of power systems are presented to test the real-time performance of this line model.
