Method of Fault Diagnosis for Power Transformer Based on Granular Computing
Abstract:Due to the incompleteness and complexity of fault diagnosis for power transformer,a method of fault diagnosis for power transformer based on Granular Computing is given in this paper.The paper describes the theory of granular computing and knowledge reduction algorithm and the algorithm is applied to transformer fault diagnosis decision table reduction.The results show that the method does not change the classification ability in the case about to redundant condition attributes and attribute values, obtain the set of minimalist diagnosis rules,which greatly improves the efficiency of fault diagnosis.
Keywords: Fault Diagnosis Power Transformer Granular Computing Knowledge Reduction
