Abstract

The invention discloses a power distribution network diagnosis index classification method based on factor regression analysis. The method comprises the following steps: dividing selected power distribution network indexes into a target layer, a main index layer and a sub-index layer by using an analytic hierarchy process; carrying out factor analysis on the current situation diagnosis index sample data to obtain a common factor of the current situation diagnosis index; and performing multivariate regression analysis, performing collinearity analysis, and deleting redundant indexes. Accordingto the method provided by the invention, the key indexes influencing the diagnosis and analysis of the power distribution network can be quickly and accurately found, the classification of the key indexes of the power distribution network can be realized, and the diagnosis and analysis efficiency and accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of distribution network planning, in particular to a distribution network diagnosis index classification method based on factor regression analysis. Background technique [0002] In the process of diagnosis and evaluation of the status quo of distribution network, a large number of index data and direct operation data related to the evaluation can be collected. These data contain a lot of information, which can fully reflect the role of various indicators in evaluating the current power grid. However, it can be seen that in most cases, the types of indicators obtained are complex and there is a certain correlation between them. The degree of contribution of the work also varies. Moreover, some indicators with different evaluation objects do not actually reflect the different factors that affect the diagnosis of the status quo of the distribution network, but the performance of factors affecting the status q...
