User electric equipment safety assessment method based on improvement section analytic hierarchy process

Abstract

The invention provides a user electric equipment safety assessment method based on an improvement section analytic hierarchy process. The method comprises the following steps that a safety assessment index system of user electric equipment is established, and an expert grades a safety assessment index; the indeterminacy value of a judgment section is converted into a determinacy type value with the improvement section analytic hierarchy process; a section judgment matrix is constructed, and the maximum eigenvalue and eigenvector of the matrix are calculated; consistency of the section judgment matrix is tested, and weights of all safety assessment indexes are determined. According to the user electric equipment safety assessment method based on the improvement section analytic hierarchy process, the user power utilization safety can be effectively assessed through the assessment result, and a powerful basis is provided for preventing the human casualty accident of power utilization safety; compared with a common analytic hierarchy process calculation result, the feasibility of the method is shown, and a certain reference is provided for the user power equipment safety assessment.

Description

technical field [0001] The invention relates to an evaluation method, in particular to a user electrical equipment safety evaluation method based on an improved interval analytic hierarchy process. Background technique [0002] Electric shock, equipment misuse, long-term disrepair of equipment, violations of regulations and other reasons often cause user-side power consumption personal injuries and deaths. According to the statistics of the National Energy Administration, in 2013, the number of deaths in power production reached 57, and the death toll in power construction reached 10. 26 major incidents of electric power safety. The deep-seated reasons for electricity safety casualties, on the one hand, are due to the insufficient awareness of safety awareness of electricity safety inspection and management personnel, or insufficient grasp of electrical equipment and safety requirements and standards; Conduct reliable safety hazard judgments on electrical equipment.

The deep-seated reasons for electricity safety casualties, on the one hand, are due to the insufficient awareness of safety awareness of electricity safety inspection and management personnel, or insufficient grasp of electrical equipment and safety requirements and standards; Reliable safety hazard judgment for electrical equipment

[0003] In terms of risk assessment of electricity safety and Interval Analytic Hierarchy Process (Interval Analytic Hierarchy Process), international and domestic scholars have carried out a lot of research and achieved some scientific research results; literature [1] in order to solve the ambiguity of expert judgment and decision-making In view of the uncertainty of factors, a comprehensive evaluation and decision-making method for urban network planning was proposed; literature [2] proposed an index system for power grid risk assessment from three aspects: assets, threats, and vulnerabilities, and calculated the weight of the index by the AHP. The process is described in detail; literature [3, 4] has a very comprehensive description of the anti-stealing technology; literature [5] quantitatively compares five different interval analytic hierarchy process index weight solutions by defining the error standard for evaluating the accuracy of the algorithm. methods; however, there are few relevant research reports on the safety assessment of user-side electrical equipment
