A New Approach of Power System Protection Based on Wavelet Transformation
Wavelet transformation has been used in many protection applications such as transmission lines, transformers and generators protection. In the previous researches, the technique of wavelet protection was applied only to protect one element of the power system, but in this paper, the wavelet protect...

Wavelet transformation has been used in many protection applications such as transmission lines, transformers and generators protection.

The proposed system is divided into three protection zones; two zones for the two generation bus bars and one zone for the transmission line. Recorded current samples of the two ends of the transmission line are obtained by matlab simulink then fed to the wavelet based detector and classifier machine to check the health of the whole power system through the approximate coefficients of the recorded signals, once a fault occurs at any of the zones, the based protection technique detects, classifies and determines the zone of fault through the detail coefficients of the current signal modal components. |
