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

The problem of. electricity 15 enormous and can never be treated completely until the faultdepartment (maintenance) is improved upon for urgent and rapid. 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 ml;St occur on botI; the transmISS}on and distribution lines but, the problem is how fast the fault can be cleared when the m'funtenance‘team has to patrol the lines (i.e from pole to pole and from tower to tower) looking for the fault. Fuzzy based controller or fuzzy logic controller is a type of cqntrol system tpat uses fuzzy logic to model the relationship between inputs and outputs. Itisa ¥nathematlca1 framework that allows for imprecise reasoning and decision making by assigning degrees of membership to different sets of categories. In this research, 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 third proposed fuzzy-set approach, faults can easily be located and treated (cleared) rapidity on both transmission and distribution lines. The obtained results in the configuration of with and without fuzzy logic controller in the reduced 132kv transmission system was acquired showing the load flow, simulation result of he system, the simulation result with fuzzy logic controller, te voltage and current measurement including the sinusoidal waveform of the voltage and current load output and possible improvement in the system.
