Problems solved by technology

[0004] Equipment condition assessment is the basis of power distribution equipment maintenance. Many domestic experts and scholars have carried out research work, but most of them stay in the qualitative analysis stage, and have not specifically quantified the degree of influence of various factors on the equipment condition.
At the same time, many scholars have applied analytic hierarchy process, fuzzy comprehensive evaluation, etc. in the research process of health status assessment, and then such methods rely on expert experience, the evaluation method is relatively single, and lacks certain objectivity

Abstract

The invention provides a power distribution equipment health state assessment method and system. The power distribution equipment health state evaluation method comprises the following steps: establishing a power distribution equipment state evaluation model by adopting a multi-stage fuzzy comprehensive evaluation method; Analyzing the defect severity of each part of the power distribution equipment in the power distribution equipment state evaluation model by using an analytic hierarchy process, establishing an evaluation matrix of each part of the power distribution equipment, and determining the weight of each evaluation index; Analyzing an evaluation matrix of each part of the power distribution equipment by utilizing a fuzzy evaluation method and the weight of each evaluation index, and obtaining a comprehensive initial score of the power distribution equipment through a weighting membership degree principle; Constructing an identification framework of the power distribution equipment state evaluation model, and determining the weight of the defect severity; And performing weighted calculation on the comprehensive initial score of the power distribution equipment and the weight of the defect severity to obtain a comprehensive score value of the health state evaluation of the power distribution equipment.

Description

technical field [0001] The disclosure belongs to the field of state evaluation of electrical equipment, and in particular relates to a method and system for evaluating the health state of power distribution equipment. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] At present, the analysis of power system failures and their main problems both at home and abroad puts more emphasis on the operation of the power system itself, while not paying enough attention to the power grid accidents caused by the failure of power equipment itself. In actual operation, the safety of power equipment operation is the top priority of ensuring the safety of power system operation. The outage of power equipment has always been one of the main factors that endanger the safety of the entire power system, especially as the core of the power system. The health l...
