3-10kV grid six-level 15-dimension status grid analysis method

Abstract

The invention relates to a 3-10kV grid six-layer 15-dimension status grid analysis method. A 10kV grid is analyzed from six levels: (1) power supply path; (2) line structure; (3) power supply capacity; (4) contact information; (5) accident safety evaluation; and (6) automation and communication. The invention provides a quantifiable multilevel evaluation method. The previous means of evaluation through perceptual knowledge, personal factors or single judgment basis is changed. With further improvement on the principle of order-of-priority distinguishing of the distribution network projects in first-class cities and with the construction of a large-scale planning system, especially, with the advance of the planning and design integration mode, higher requirement is put forward on project selecting and sorting. With the distribution network project sorting system, problems, for example, evaluation can hardly cover all project types, the subjective factors account for a significant proportion in the scoring process, and the reference value of the scoring result is reduced, are solved.

Description

technical field [0001] The invention belongs to the field of power transmission networks, in particular to an analysis method for a 3-10kV power grid with six layers and 15 dimensions of the current power grid. Background technique [0002] At present, the analysis level of 10kV power grid is relatively messy, usually based on perceptual knowledge, personal factors or evaluation methods based on a single evaluation basis. Evaluation is difficult to cover all project types, and subjective factors account for a large proportion in the evaluation process, resulting in a reduction in the reference value of evaluation results, etc. Problems, the analysis of power grid problems is incomplete, resulting in a lack of deep analysis of the current power grid. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method for analyzing the current situation of a 3-10kV power grid with six layers and 15 dim...
