配電變壓器更換優(yōu)先級(jí)模型
[Abstract]:Aiming at the priority problem of distribution transformer replacement, a multi-level distribution transformer replacement priority model based on fuzzy analytic hierarchy process (AHP) and grey fuzzy theory is proposed, which covers many evaluation factors. The model includes the establishment of evaluation system and the corresponding calculation method. Firstly, the fuzzy analytic hierarchy process (AHP) is used to establish the AHP model for different kinds of evaluation factors, and the weight of each factor is determined, and the gray level of the weight is determined according to the expert experience, and the weight matrix is established. Secondly, the deterioration function is used to process the data, and the membership function is used to describe the membership relationship between the data and the evaluation grade, and the grey fuzzy matrix is established to describe the adequacy of the data. Finally, the weight matrix and grey fuzzy matrix are synthesized, and the evaluation results are obtained according to the maximum membership degree. The calculation example shows that the model can comprehensively consider many factors and improve the fuzziness and gray of the data, and reasonably evaluate the replacement sequence of distribution transformer, which provides a reference for the economic operation of distribution transformer.
