Location Of Fault On A Microgrid Using Travelling Wave And Wavelet Transform Method

Abstract

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 for calculating the location of fault using wavelet transform and the travelling wave 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 fault is done using travelling wave method and wavelet transforms method. The comparison results are presented which demonstrates the enhanced performance of both the methods.
