基于组合权重及改进可拓原理的电力变压器部件风险等级评估
The risk level evaluation of power transformer parts based on combination weighting and extension theory
摘要
Abstract
The process of power transformer quality control in whole life cycle will lead to unnecessary waste of resources,usually because the key is unknown.On the basis of statistical analysis,this paper divides the power transformer into seven parts and builds a comparatively perfect risk level evaluation system.Through the introduction of entropy and improved extension matter-element evaluation method,we integrate the risk level assessment with quantitative analysis to reduce the influence of subjective factors.It is a reasonable solution to the uncertainty and fuzziness of the evaluation process,meanwhile,it improves the traditional extension theory defects relying on the maximum membership degree principle which lead to the result inaccurate.The component risk sorting has a certain guiding significance for the whole life cycle power transformer quality control.关键词
