Application of an Intellectual Fault Diagnosis for the Power Transformer Based on the Rough Set Theory
Hai-Qun Yu · Techniques of Automation and Applications · 2009
Based on the dissolved gas analysis of the transformer oil,the rough set theory is introduced for the attribute optimiza-tion of the its application in characterized parameters.The discernibility matrix algorithm is used to reduce attributes in the decision table.The unnecessary attributes are eliminated,and the inner redundancy of the fault diagnosis system’s condition attributes is revealed.
