Abstract

The invention discloses a transformer state knowledge acquisition method and equipment based on genetic algorithm and attribute support degree. The method establishes a decision table through transformer fault cases, combines the genetic algorithm and attribute support to solve the state knowledge under the abnormal information of the specific state of the transformer, and finds the evolution law of the transformer state. Compared with the traditional method, the calculation complexity is greatly reduced, which is conducive to efficient extraction and decision-making The most relevant condition attributes in the table for the type of transformer fault. This method can overcome the shortcomings and deficiencies of the existing technology, and can be widely used to understand the development law of transformer status, realize transformer status evaluation, guide transformer status monitoring and formulate differentiated operation and maintenance strategies, and the method is simple and efficient, which is conducive to improving power consumption The operation of the transformer is safe.
