Comprehensive evaluation method for power receiving engineering construction quality of power customers at 10kv or below

Abstract

The present invention provides a method for comprehensive evaluation of the construction quality of power receiving projects for power customers of 10 kv or below, comprising the following steps: S1, constructing an evaluation index system, the evaluation index system includes a first-level indicators and b second-level indicators, wherein , a and b are both natural numbers, S2, respectively construct a judgment matrix for pairwise comparison between the first-level indicators and the second-level indicators, S3, calculate the weight of each first-level indicator and second-level indicator, S4, establish a comprehensive fuzzy evaluation model, The specific method is for the object to be evaluated, rating the secondary indicators described in step S1 by several experts, S5, calculating the membership matrix R according to the statistical results of step S4, S6, according to the weight of the membership matrix R and the secondary indicators , respectively calculate the evaluation vector of each first-level index, S7, calculate the fuzzy comprehensive vector B according to the weight of the first-level index and the evaluation vector of each first-level index, S8, quantify the score. Using fuzzy comprehensive evaluation method based on AHP, the evaluation result is more scientific and reasonable.

Description

technical field [0001] The invention relates to the field of project construction quality evaluation, in particular to a method for comprehensive evaluation of construction quality of power receiving projects for power customers of 10kV and below. Background technique [0002] Under the new situation that my country's power grid construction is constantly increasing, the position of 10kV and below customer power distribution projects is becoming more and more important. It is necessary to strengthen its project management and improve the quality of project construction in order to better meet the needs of enterprises and people. electricity demand. On the other hand, for the electric power company, the public transformation part of the 10kV and below customer power distribution project must be handed over to the electric power company for operation and maintenance management. In order to ensure that the cost and difficulty of operation and maintenance in the later stage are ...

AI Technical Summary

Problems solved by technology

[0004] The present invention discloses a comprehensive evaluation method for the construction quality of power receiving projects of 10kv and below electric power customers. In the process of fuzzy comprehensive evaluation, the analytic hierarchy process is used to determine the weight of each index, which solves the problem of simply using the expert estimation method in the existing evaluation methods. To determine the weight of the indicator is too much affected by human factors, resulting in the defect that the result is not accurate and reasonable
