Research on Evaluation Method of Greenness of Transmission and Substation Equipment Based on Improved Fuzzy Object Element
To provide reliable data to support the implementation of energy-saving and environmental protection strategy for smart grid,and to improve the evaluation effect of greenness of transmission and substation equipment,the evaluation method of greaness of transmission and substation equipment based on improved fuzzy object element is propsed.Firstly,based on the hierarchical analysis method,the greenness evaluation indexes of transmission and substation equipment are screened from four perspectives:environment,energy,resources and economy,to construct the greenness evaluation index system of transmission and substation equipment.Then,the hierarchical analysis method and entropy weight method are used to calculate the comprehensive weight of greenness evaluation indexes of transmission and substation equipment,and to establish the fuzzy object element model of greenness evaluation of transmission and substation.Finally,by calculating the Euclidean closeness between the greening scheme and the standard scheme of transmission and substation equipment,the determination of the greenness evaluation level of transmission and substation equipment is completed to achieve the purpose of greenness evaluation of transmission and substation equipment.The test results show that the proposed method can calculate the transmission and substation greenness evaluation indexes at all levels weights and comprehensive weights,accurately evaluate the greenness level of transmission and substation equipment,and the evaluation results are consistent with the actual results.The method can accurately reflect the green degree of transmission and substation equipment,and provide an important reference basis for equipment selection,operation and maintenance.
