Method and device for analyzing reasonable value of line loss benchmark of power distribution network

Abstract

The invention discloses a method and a device for analyzing a reasonable value of a line loss benchmark of a power distribution network. The method comprises the steps of determining line loss data sample sets of a plurality of analysis dimensions based on equipment parameter information and theoretical line loss result data required by theoretical line loss of a power distribution network; performing system clustering analysis on the line loss data sample set under different analysis dimensions to form a reference clustering value scale; analyzing the line loss data sample set under differentanalysis dimensions by adopting a preset clustering algorithm based on the reference clustering value scale so as to select a target clustering value; determining a plurality of line loss reference domains based on the target clustering value, each line loss reference domain comprising a plurality of sub-analysis factors; and determining a line loss benchmark reasonable value corresponding to each analysis dimension by utilizing the data analysis decision tree and the plurality of line loss reference domains.

Description

technical field [0001] The invention relates to the technical field of distribution network line loss evaluation, in particular to an analysis method and device for a reasonable value of distribution network line loss benchmark. Background technique [0002] In related technologies, with the development of the economy, the dependence on electric energy continues to increase. In the field of distribution network, the line loss management of the distribution network is a very complicated problem. Since there are many factors that affect the line loss rate, so in When calculating the line loss of the distribution network, it is necessary to comprehensively consider different use environments, line directions, voltage levels, etc., but currently there is no reasonable line loss benchmark analysis method for the selection of distribution network line loss, which will lead to distribution network line loss. The loss problem cannot provide a reasonable calculation method, and quant...
