Frequency is a vital factor for power system operation and protection. This paper is on extraction of frequency feature for fault/event analysis based on wavelet transform (WT) and fractal geometry (FG). The frequency signal is decomposed by WT-based multiresolution analysis (MRA) and a family of wavelet coefficients is obtained. A maxima line is constructed by connecting the maximum point in the...
With the increased penetration of distributed generation (DG) on power systems, there is much research to look into the impact of the DG on the operations of the power systems. While often there is a concern that the DG will have an adverse effect on the power system, the presence of an alternative source provides an opportunity to use the capabilities of the source to enhance and support the system...
