摘要：

The correct classification of power quality disturbances is the premise and basis of governance and control of power quality problems. This article extracts the instantaneous amplitude of the signal before and after the disturbance by HHT, combining S-transform of the disturbance signals to extract high-frequency and low-frequency characteristics, as to achieve the classification of power quality disturbances. Experimental results show that the fusion of the two methods can accurately detect the categories and disturbance characteristics of power quality disturbance signals, the starting and ending time of disturbance signals.
