摘要：
The wavelet transform has been applied for years in the fields of image compression, acoustic, ect. It has also been introduced in power system detection and analysis these years. In this paper, the application of the wavelet analysis on the ferroresonance in power system is introduced. A typical type of the ferroresonance resulted by the saturated voltage transformer (VT) is analyzed by the wavelet transform. The analysis shows the application of wavelet transform can detect the occurrence of the ferroresonance, and the frequency of the ferroresonance also can be determined. With the information that is provided by the wavelet transform, the power system can get a good protection from the ferroresonance.
