A high-reliability power supply area distribution network planning effect comprehensive evaluation method

Abstract

The invention relates to a high-reliability power supply area distribution network planning effect comprehensive evaluation method. The method comprises the following steps of 1) establishing a planning effect index evaluation system comprising a criterion layer and an index layer; 2) determining a high-reliability power supply area distribution network planning scheme by combining different gridstructures, electrical equipment types, an automatic configuration method and a communication construction method; 3) obtaining basic data of the distribution network planning; 4) determining the weight of each criterion in the criterion layer; 5) determining the weight of each index in the index layer; 6) determining the score functions of the indexes respectively; 7) obtaining a comprehensive evaluation result. The method has the advantages that a distribution network planning and construction decision maker is helped to select an appropriate high-reliability power supply area distribution network planning scheme, and the problems that a high-reliability power supply area distribution network planning effect index evaluation system is unclear, an evaluation result is fuzzy and the like are solved.

Description

technical field [0001] The invention relates to the field of comprehensive evaluation of distribution network planning effects, in particular to a method for comprehensive evaluation of distribution network planning effects in high-reliability power supply areas. Background technique [0002] With the rapid acceleration of my country's urbanization process, the construction of high-reliability power supply areas such as new urban areas and economic development zones is in full swing. The high-reliability power supply area is generally within the scope of A+ and A-type power supply areas stipulated in the "Technical Guidelines for Distribution Network Planning and Design", and has a relatively large impact on the economy, safety, reliability and technicality of the distribution network during planning and construction. high demands. [0003] At present, scholars in the industry and at home and abroad have carried out research on distribution network planning schemes for high...

AI Technical Summary

Problems solved by technology

Due to the many factors involved in the planning and construction of the distribution network, the evaluation indicators for the planning effect of the high-reliability distribution network construction have been varied for a long time, so that decision makers have no unified standard when choosing the planning scheme for the construction of the high-reliability distribution network.
