An Algorithm for Harmonic Detection Based on Wavelet Transform

摘要：

Power system harmonics is produced in the power transmission link. It has impacts on the transmission equipment, communication systems and human. There are the nonlinear loads in the power system, harmonic is inevitable. So harmonic analysis is very important. This paper analyses problems in the spectral aliasing in the field of harmonic analysis and provides an algorithm solve the problem of the spectrum aliasing. The .simulation result proves that the algorithm is useful in how to reduce the aliasing components in the signal processing. It provides protection to the follow-up work and it is conducive to harmonic signal analysis and processing in the power system.
