Abstract
The multiresolution analysis generated by the compactly supported cardinal B-spline wavelets for data smoothing is introduced. It is shown that the proposed technique has the advantages of high accuracy and low delay and may be used instead of the traditional low-pass filters for power system protection. Its applications in digital distance protection are presented in detail. Simulation studies using EMTP have shown that the wavelets-based method can reduce the relaying time and may be suitable for digital distance protection.
