Quantitative evaluation method for credibility of distribution transformer inspection result based on LOF algorithm

Abstract

The invention provides a quantitative evaluation method for credibility of a distribution transformer inspection result based on an LOF algorithm. The quantitative evaluation method comprises the following specific steps: 1, collecting and arranging sample data; 2, standardizing data, and establishing a data set; 3, carrying out LOF model training, and establishing a judgment model; and 4, quantitatively evaluating the credibility of the distribution transformer measurement result, quantitatively evaluating the credibility of the inspection report according to the abnormal score, finding out asuspected abnormal detection report according to the set abnormal score, and completing the quantitative evaluation of the credibility of the distribution transformer inspection result. The quantitative evaluation method establishes a training model by using an LOF algorithm, according to the obtained training model, carries out quantitative scoring on a distribution transformer inspection result, can judge whether the result is abnormal or not, and can calculate and sort the abnormal scores, so that an inspector can judge the abnormal degree of the inspection result, and the quantitative evaluation problem of the credibility of the inspection result of the distribution transformer can be accurately solved.

Description

technical field [0001] The invention belongs to the field of material detection in electric power systems, and proposes a quantitative evaluation method for the reliability of distribution transformer inspection results based on LOF algorithm. Background technique [0002] Power grid material quality inspection refers to the work of testing the power equipment and materials supplied to the State Grid Corporation through on-site witnessing, random testing, and third-party testing. The main purpose of carrying out the quality inspection of power grid materials is to ensure that the quality of equipment and materials entering the power grid meets the standard requirements, and to prevent unqualified materials from flowing into the production and operation links and endangering the safety of the power grid. In recent years, with the development of science and technology and the expansion of the grid scale, the types of power materials have been continuously enriched, and the num...
