Abstract

The invention discloses a power network area division method based on an evaluation index system of a power distribution network and clustering analysis. The power network area division method comprises the following steps of: S1, selecting multiple primary indexes capable of reflecting the current situation of a power distribution network in a certain urban, and establishing the evaluation index system of the power distribution network by utilizing a systematic clustering method; S2, determining the comprehensive weight of each evaluation index in each class in the evaluation index system by adopting a subjective and objective analysis method, in which an improved hierarchical analysis method and an entropy weight method are combined, and, in combination with a scoring value of each evaluation index, obtaining the comprehensive score of the power distribution network in an evaluated area; and S3, performing clustering analysis of the comprehensive score of the power distribution network in the evaluated area so as to obtain a classification result of the power distribution network in the whole area. According to the power network area division method disclosed by the invention, on the basis of the general characteristics of the power distribution network, the development current situation and the development capability of the power distribution network are scientifically evaluated; and practical and reliable basis is provided for determining a key factor influencing development of the power distribution network.

Description

technical field

[0001] The invention belongs to the technical field of distribution network area division, and in particular relates to a distribution network area division method based on distribution network evaluation index system and cluster analysis. Background technique

[0002] The scientific and reasonable division of power grid areas has always been a research hotspot in the development of power grids. By dividing multiple local distribution networks in a large area, the development direction and route of different types of distribution networks can be studied, so that Differentiation meets the overall development needs of the power grid in the region.

[0003] The division of power grid areas is affected by many factors such as the average power supply radius of the main line, the proportion of cross-sectional radius that meets the requirements of the regulations, the reliability rate of power supply, and the pass rate of comprehensive voltage. These factors will a...
