摘要：
In this paper, the load of electro discharge machining (EDM) is used to extract the mutation characteristics of pulse energy. In this paper, different wavelet basis functions and thresholds are used to denoise the electrical load characteristics of EDM, and the wavelet denoising function and threshold for different practical situations are obtained, which provide the basis for pulse power quality analysis. What's more, a method to identify the impulsive power quality mutation information based on S-transform is proposed, which realizes the automatic recognition of power quality during EDM operation, and the extraction accuracy is high.
