The improved protection technique for zone 3 can help to prevent such mal-operation and, thus, more reliable power systems can be envisaged.

Since three phase fault rarely occurs in the system and in order to have better demonstration of effectiveness of the proposed scheme, it is tested for various type of faults such as, two pha se (AB), single phase to ground (AG) and two phase to ground (ABG) as well as three-phase (ABC) using data simulated through DIgSILENT in the IEEE 30-bus test system during different topologies. The simulation results show that the novel zone 3 distance relay lements using the proposed method operate correctly for various events. 2015 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47436895008 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.1 Vol.13 |
