Analysis of Power Quality Disturbances Based on S-Transform
MA Dan-dan · Journal of Shanghai University of Engineering Science · 2011
According to the main features of power quality disturbance signals,one detection and classification method of voltage signal based on S transform module matrix was proposed,and the power quality with disturbance signals were classified.The S-transform was applied to analyze the power quality disturbance signals such as the voltage sag,voltage spike,transient random disturbance and the time-frequency contour maps constructed can display different voltage disturbances intuitively.
