Embodiment Construction

[0054] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0055] The invention applies the proposed substation energy efficiency evaluation method based on the entropy weight method and the analytic hierarchy process to the 110kV substation energy efficiency evaluation. Considering that my country has a vast territory and the energy consumption of substations in different regions is greatly affected by local climate conditions and social and economic development status, three typical substations were selected in Langfang City, Hebei Province and Shaoyang City, Hunan Province, respectively, for a period of one year. Pilot load data analysis.

Abstract

The invention belongs to the field of an electric power system and particularly relates to a substation energy efficiency evaluating method based on an entropy method and a layer analysis method. By applying the layer analysis method and the entropy method in the energy efficiency evaluation of the existing substation, the influences of subjective and objective factors on the energy efficiency evaluation of the substation are covered; and the substation energy efficiency evaluating method has a great reference function to the on-site energy efficiency evaluation of a substation and can serve as a reliable and practical evaluation method for guiding the design of the substation and for operators to conduct energy efficiency evaluation, thus filling up the blank in the substation energy efficiency evaluation technology at home and abroad and greatly improving the economic operation level of the existing substation. Simultaneously, an index system of the energy efficiency evaluation of the substation can well solve a series of practical problems in the energy efficiency evaluation of the substation, guide scientific and reasonable new-construction and energy-saving renovation projects of the substation in practical design and economic operation and ensure the safety and economical operation of the substation, thus bringing huge economic benefits.

Description

technical field [0001] The invention belongs to the field of electric power systems, and in particular relates to an energy-saving evaluation method for a substation based on an entropy weight method and an analytic hierarchy process, in particular to an energy-saving evaluation method for a substation with a voltage level below 110kV. Background technique [0002] As a key link in power transmission and distribution, the energy saving and emission reduction work of a large number of substations is of great significance. Substation energy-saving evaluation is aimed at substations in different stages of planning, design and operation, combined with the national regulations on energy efficiency limit values ​​and energy-saving evaluation values ​​of products, and adopting modern system analysis theory to formulate corresponding substation energy-saving evaluation methods and evaluation standards to form a unified evaluation system and norms. On this basis, carry out systemati...
