Abstract :
In this paper real-time simulation, analysis, and validation of the conventional distance relay based on MATLAB/simulink and Real-Time LABoratory (RT-LAB) is presented. In addition to the detailed model of six impedance measuring units of distance relay, power system model is implemented in Opal-RT´s RT-LAB simulator. Some cases are highlighted to illustrate the modelling performance. Moreover, the effect of infeed current, which is an emerging issue for power system protection, using conventional distance relay in real-time environment is evaluated.
