Location Of Faults On A Hybrid Power System Using Impedance And Wavelet Transform Method

Faults should be cleared on the transmission line as soon as possible. Smaller time for the fault clearing has many merits like less threat of damaging equipment's, reduced loss of income, better customer satisfaction due to improved quality and reliability of power supply. Fast restoration of supply is possible, if accurate location of fault method is used. This paper gives the basic idea of the fault location calculation using the impedance method and wavelet transform method in a DG based power system. One practically applicable 3-bus system incorporated with various types of distribution generations are considered for the protection analysis purpose and is simulated using MATLAB/SIMULINK environment. The location of the fault is done using impedance based method and wavelet transforms method. The comparison results are presented which demonstrates the enhanced performance of both the methods.
