摘要

In this paper, a detailed study and analysis has been done for investigating a technique for the location of fault in a long high voltage DC transmission line, say up-to 1000kms long. For achieving this, the paper proposes to use combination of two methods, first method is based on the travelling wave principle, and second method is wavelet transform. The wave-front i.e. the arrival time of the travelling wave is measured with the help of wavelet transform and in wavelet transform specifically continuous wavelet transform is used because of its prominent and accurate results. The presented technique can accurately predict the exact fault location, with the help of correctly measured surge arrival times obtained from continuous wavelet transform. The studies are carried out with the detailed simulation model as well as programming in MATLAB.
