Power equipment reliability evaluation based on data mining

摘要

Electrical power equipment reliability is the basis of the stability operation of distribution network. Equipment reliability includes inherent reliability and operational reliability. Inherent reliability focus on familial defects. Operational reliability focus on meteorological, load rate and others. This paper evaluates power equipment reliability based on integration platform of Jiangsu province electric power company. The inherent reliability and operational reliability are researched separately. The quantitative relationship between fault and condition is researched based on data mining. Weighting coefficients is calculated to combine different factors. On this basis, the reliability evaluation model is constructed and develop the relative software. Operation shows that power equipment reliability evaluation system has engineer applicability and practicality.
