Quantitative Evaluation Method of Turbine Virtual Maintenance Based on Improved AHP

Abstract

In order to evaluate the training process of steam turbine virtual maintenance for personnel training more reasonably, a quantitative evaluation method of turbine virtual maintenance based on improved analytic hierarchy process (AHP) is proposed in this paper. This paper establishes a set of evaluation index system and gives the quantitative algorithm of the corresponding index according to the characteristics of virtual maintenance of steam turbine equipment. The traditional AHP is also improved without consistency checking, which avoids the blindness of artificial adjustment of the judgment matrix and makes it easier and faster to get the weight value of the index. Under the balanced consideration of all evaluation factors, the evaluation of operators is completed, and the results of the comprehensive evaluation are more objective and credible. This method has been applied to a virtual maintenance training and assessment platform of steam turbine in thermal power plant, and the validity of the method has been verified.
