[0059] 1Establishment of the project evaluation index system for the distribution network area

[0060] There are many factors that affect the selection of distribution network station area projects, and the use of systematic, scientific and practical evaluation indicators is the key to the selection of distribution network station area projects. Through extensive investigation and research, fully absorb the experience of the domestic advanced provincial and municipal project selection evaluation index system, and at the same time combine the characteristics of city A, comprehensively consider from multiple perspectives such as economy, technology, and data availability, and add the influence of investment optimization , analyzing the influencing factors of project selection in the distribution network area, and obtaining the first-level index. The first-level indicators are decomposed by the fishbone analysis method, and the influencing factors of the distribution network sta...

Abstract

The invention discloses a power distribution district project optimization evaluation method based on G1-entropy weight method. The method comprises the steps of power distribution district project evaluation index system establishment, index preprocessing, weight setting, project comprehensive optimization and the like. The evaluation index system fully considers basic data and operation and maintenance data of a transformer area, and considers investment benefits; the index weight is calculated by using the G1-entropy weight method; the optimization model based on project evaluation comprehensively considers necessary implementation projects of expert decision-making during fund arrangement, and two factors of scientific project sorting and expert decision-making are well considered. Example analysis indicates, the method can be applied to investment plan compilation management work of city power supply bureaus and county power supply bureaus. Theoretical basis and method reference are provided for power distribution district project optimization and fund arrangement, scientificity and reasonability of district project investment decision are enhanced, low-efficiency or ineffective investment is avoided, operation risks are effectively prevented and avoided, and the investment decision management level is further improved.

Description

technical field [0001] The invention belongs to the technical field of electric power construction, and in particular relates to an optimal evaluation method for distribution station area projects based on the G1-entropy weight method. Background technique [0002] In recent years, with the acceleration of the new round of rural network transformation, the investment in distribution network has increased year by year, accounting for more than 50% of the investment in medium and low voltage distribution network. Due to the lack of effective evaluation methods, the investment decision-making basis is insufficient, and even though the investment continues to increase, the situation of heavy overload and low voltage in the station area is still prominent. Taking the A network area as an example, there are about 20,000 units in the public substation area, 15% of which have heavy overload and low voltage problems, which do not match the people's increasing requirements for "good u...
