AN IMPROVED FAULT LOCATION ON POWER SYSTEM TRANSMISSION LINES USING FUZZY LOGIC APPROACH

ABSTRACT The problem of electricity are enormous and can never be treated completely until the fault department (maintenance) are improved upon for urgent and rapid response to line faults. The present protection scheme only isolates the lines in the event of faults, define the fault, but leaves no proper information about the location of the fault. Faults must occur on both the transmission and distribution lines but, the problem is how fast the fault can be cleared when the maintenance team have to patrol the lines (i.e. from pole to pole and from tower to tower)looking for the fault. In this project, fault location based fuzzy logic is developed. This approach is motivated by the fact that the input impedance to which distinct. The technique shows the line operational data, rules that is simulated using fuzzy logic toolbox in MATLAB. By this proposed fuzzy-set approach, faults can easily be located and treated (cleared) rapidity on both transmission and distribution lines.
