%0 Journal Article %T The Distance Measuring Units Algorithm Synthesis On The Basis Of The Earth Fault Specified Model %A Tatjana Lomane %A Viktorija Belugina %A Ren¨Ħrs Koemecs %J Journal of Computer Science and Control Systems %D 2009 %I Editura Universit??ii din Oradea %X The distance protection is the most common protection of the electric power transmission lines. However, the distance measuring units operation during the earth fault through the fault resistance is not always effective. This paper presents the new earth fault distance protection measuring units algorithm, which is based on the precise model of the protective object during the earth fault. It is obtained the estimations of the operation effectiveness of new and classical algorithms for the distance protection in the different earth fault regimes with different values of fault resistance. %K distance protection %K earth fault %K effectiveness %U http://electroinf.uoradea.ro/reviste%20CSCS/documente/JCSCS_2009/Articole_pdf_JCSCS_A_nr_1/JCSCS_2009_Nr_1_AA_Lomane_The_distance.pdf
