- Abstract
The tapped lines are usually used to supply small communities or facilities in sparsely populated and isolated rural areas. Locating faults in such lines are difficult regarding the effect of infeed/outfeed current from tapped lines as well as reactance effect. To deal with mentioned problems a novel one ended fault location algorithm is presented in this paper, which applies generalized models of fault loop voltage and current to formulate the fault location algorithm. The derived algorithm has a very simple first-order formula and does not require knowledge of data from other ends. This feature becomes more significant in the case of isolated rural areas where it may not exist proper communicational link to exchange data with main ends. The methodology is based on calculating the current distribution factor and estimating the current from two other ends, so it measures the exact distance from fault locator to fault point. The result of simulation for three ended transmission line verifies the high accuracy of the method with regard to various equivalent source impedances, fault resistances and locations as well as fault types. Finally the algorithm expanded to multi-tapped lines and the results demonstrate the high accuracy and robustness of the proposed algorithm.
