Application of Information Entropy Based on Random Set Theory to the Fault Diagnosis of Wind Turbine Generating Units

Because of D-S combination rule has disadvantage in dealing with high confliction between evidences, this paper, from the view of random set, discusses an information decision-making method based on the information entropy. Finally, this paper's method is applied to an example of actual fault diagnosis of wind turbine generating units and compares it with D-S combination rule, validating the feasibility of this paper's method in the practical example.
