Abstract

According to a first-class city power distribution network evaluation method based on the cloud model and the possibility analysis provided by the invention, a set of comprehensive and reasonable first-class city power distribution network evaluation index system is formed from four dimensions of reliability, economy, low carbon and intelligence. The method comprises steps of on the basis of establishing the index system, converting expert semantic description information by utilizing a cloud model, and accurately reflecting randomness and fuzziness of qualitative information; on the basis ofthe cloud model, fusing the cloud models generated by the data indexes and the semantic indexes to obtain a comprehensive cloud model, and achieving qualitative-to-electric-quantity conversion; and analyzing and sequencing the quantitative interval values obtained by the comprehensive cloud model by using a possibility degree analysis method to obtain a final evaluation result. According to the method, one-stream city power distribution network evaluation can be well carried out on each region, and compared with the actual situation, it is proved that the evaluation method provided by the invention has very high feasibility, and the evaluation value has relatively high discrimination.

Description

technical field

[0001] The invention belongs to the technical field of distribution network, and designs a distribution network evaluation method, in particular relates to the state evaluation of distribution network of first-class city distribution network and ubiquitous power Internet of things. Background technique

[0002] With the continuous development of State Grid's work on "first-class city distribution network" and the proposal of "Ubiquitous Power Internet of Things" in this year's two sessions, my country's distribution network has ushered in a new round of development opportunities. In order to further respond to the vision of the power grid company's strategic goal of building the "Ubiquitous Power Internet of Things", power companies need to evaluate the distribution network within their jurisdiction. The traditional first-class city distribution network evaluation system conducts a brief evaluation of the distribution network by extracting relevant operating ...
