Estimation of Fault Resistance Using Fault Record Data PROJECT TITLE :Estimation of Fault Resistance Using Fault Record DataABSTRACT:Information concerning typical fault resistances of transmission lines will facilitate improve the settings of distance relays. This paper proposes an offline technique for estimating the fault resistance of transmission lines using the COMTRADE fault files offered from digital distance relays. The proposed method uses the fault records at each ends of a line, however synchronization of the info sets isn't needed. Simulation and lab experimental results show that the estimated fault resistance has good accuracy with a pair ofp.c average error. Finally, the method was applied to estimate the fault resistances of more than 50 section-to-ground faults of a utility company. The ranges of fault resistance values are determined for faults on the corporate's 240 kV and 138 kV lines. Did you like this research project?
