摘　　要：结合国内外采用S变换应用于电能质量扰动分析的现状,对基于S变换的电能质量扰动检测、识别以及其他方面的应用进行了分类和总结。分析了S变换结合各种人工智能与数学工具在进行电能质量扰动分析时的优势和不足,介绍了近年来利用广义S变换、改进S变换和双曲S变换等其他形式S变换在电能质量扰动分析中的应用情况。最后对S变换应用于电能质量扰动分析的发展趋势以及值得进一步研究的问题进行了展望。On the basis of the application status of S-transform in power quality disturbances analysis at home and abroad,the S-transform based power quality disturbance detection,classification and application in other aspects are summarized and classified.The advantages and disadvantages of using S-transform combining with various artificial intelligent and mathematical tools to analyze power quality disturbance are analyzed. The situation of other forms of S-transform in recent years such as generalized S-transform,modified S-transform and hyperbolic S-transform applied to power quality disturbance analysis is introduced. Finally,the developing trend and further issues of using S-transform to analyze power quality disturbance are presented.
