| Abstract | ||||
| The change in power systems can affect the performance of distance relays protection. In case of distance protection especially the state of double circuit operation depending on the power system state, a distance relay can cover from less than 50% up to far more than100% of the total line length. The mutual magnetic coupling is one of the phenomenon affecting the precision of the distance relay. An adaptive distance protection scheme of a double circuit transmission line considering the mutual magnetic coupling effect is presented in this paper. The single line to ground fault (SLG) and the line to line to ground fault (LLG) in a double circuit transmission line are studied. An adaptive correction factor in case of SLG and LLG faults for the compensation of the mutual coupling effect is suggested and calculated. It's achieved using the simulation results of ATP-EMTP program without and with considering the mutual coupling effect. The proposed adaptive protection is applied to a double circuit transmission line model and the results are reasonable. | ||||
