A summary of S-transform applied to power quality disturbances analysis

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.
