Aiming at the problems of single evaluation index, strong subjectivity and lack of accuracy of evaluation results in the traditional evaluation model of secondary equipment in power system, a comprehensive evaluation method of secondary equipment operation status based on matter-element extension theory is proposed. First, build a comprehensive evaluation index system for the operation status of secondary equipment. Secondly, the subjective and objective weights of the evaluation indicators are calculated based on the attribute hierarchy model and the anti-entropy weight method. On this basis, the combined weights are calculated using the cooperative game model. Finally, based on matter-element extension theory, a comprehensive evaluation model of secondary equipment operation status is built. The case analysis shows that this method can improve the rationality and accuracy of the secondary equipment condition evaluation results, and provide effective assistance for the operation, maintenance and repair of secondary equipment.
