Abstract:ABSTRACT: A novel method for identifying and recognizing the common power quality disturbance signals based on the general wavelet entropy is presented in this paper. The wavelet entropy of different power quality disturbance signals in a series of scales is calculated, and the general wavelet entropy distri-bution characteristics of different power quality disturbance signals and important scale selection of sample entropy algo-rithm are given. Finally, a support vector machine is applied for different power quality disturbance signals recognition and the result shows that the average classification accuracy is above 96%. |
