Embodiment Construction

[0067] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0068] Please refer to figure 1 , the present invention provides a multi-dimensional comprehensive evaluation method for distribution network construction based on improved composite weighting, comprising the following steps:

[0069] Establish a multi-dimensional comprehensive evaluation index system for distribution network. The comprehensive evaluation index system is a unified evaluation whole composed of several interrelated and several independent factors according to the set hierarchical structure. Preferably, in this embodiment, a first-level evaluation index system is composed of normative rationality check indicators, construction necessity and feasibility indicators, construction site inspection indicators, and overall control indicators. Among them, the normative rationality verification index, construction necessity and feasibility index ...

Abstract

The invention relates to a power distribution network construction multi-dimensional comprehensive evaluation method based on improved composite weighting, and the method comprises the following steps: obtaining power distribution network engineering detection influence factors, and constructing a multi-dimensional comprehensive evaluation index system composed of a first-level basic index and a second-level refined index; and according to the multi-dimensional comprehensive evaluation index system, carrying out composite calculation on the weight of each index by utilizing a composite method of an improved analytic hierarchy process and an anti-entropy weight method, and constructing a multi-dimensional comprehensive evaluation model in combination with confidence. According to the invention, comprehensive evaluation of power distribution network engineering construction is realized, the engineering construction problem is optimized, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to a multi-dimensional comprehensive evaluation method for distribution network construction based on improved composite weighting. Background technique [0002] The electric power system is the entity system with the largest scale, particularly complex layers, and extremely strict real-time requirements in various industrial sectors. As an important part of national economic development, its safe and stable operation is very important. In recent years, the voltage level and transmission capacity have also been continuously improved, but the ensuing equipment and engineering problems have also become important factors affecting the stable operation of the power grid. As an intermediary between the power system and user connections, the distribution network plays an irreplaceable role in the entire power system. [0003] As the last link in the power grid to transmit electric energy to users, the distribution network is responsibl...
