Abstract

The invention discloses a method for estimating a 20-kilovolt medium-voltage distribution scheme, which belongs to the technical field of the application of electric industry. In the method, an estimation index system of the 20-kilovolt distribution scheme is established by an analytic hierarchy process (AHP), and a data envelopment analysis (DEA) estimation model with an AHP preference cone is improved, wherein the provided AHP / DEA model is used for solving the weight of an index. By the method, the problem that 9 comparison objects cannot be exceeded in the conventional method is solved and the problem of combining subjectivity and objectivity reasonably in estimation by introducing a relaxation factor is also solved properly.

Description

technical field

[0001] The invention belongs to the technical field of electric industry application, and in particular relates to a method for evaluating a 20-kilovolt medium-voltage power distribution scheme. Background technique

[0002] The selection of the 20 kV medium-voltage distribution voltage level of the power system is a strategic issue for the development of the power industry and an important technical decision in the power field, which is related to the development of the power grid and even the entire society. It is affected by many factors and affects many aspects at the same time. Therefore, the determination of the power distribution scheme must be carefully planned and carefully considered.

[0003] At present, there are a series of models and methods in the specific methods and steps of reasonably selecting the voltage level of the urban distribution network, as well as the evaluation and selection of the 20 kV distribution network, and it can be conclud...
