摘要/Abstract

摘要： 为实现精准评估充电站设备健康状态, 有效预判设备运行态势,提出一种充电设备健康状态评估方法。首先, 通过对充电桩技术和功能特点进行分析, 构建健康状态综合评估指标体系。其次, 采用层次分析法 (AHP: Analytic Hierarchy Process)计算主观权重和基于指标间相关性的指标权重法(CRITIC: Criteria Importance Through Intercriteria Correlation)计算客观权重, 并基于合作博弈理论将主客观权重线性组合成综合权重。引入正态分布云模型作为评估模型的隶属度函数,通过计算各指标的隶属度函数值,构建不同健康状态等级对应的隶属度矩阵,进而计算出各指标综合得分。最后,对某充电设备实时运行数据分析,验证评估模型的可行性。该评估方法能够准确量化充电设备的健康状态,为充电站的预防性维护和故障预警提供科学依据。

关键词: 健康状态评估, 层次分析法, 指标相关性权重法, 正态分布云模型

Abstract: To accurately assess the health status of charging station equipment and effectively predict the operational trends of the equipment, a health status assessment method for charging equipment is proposed. Firstly, by analyzing the technical and functional characteristics of charging piles, a comprehensive health status assessment system is constructed. Secondly, the AHP(Analytic Hierarchy Process) is used to calculate the subjective weights, and CRITIC(Criteria Importance Through Intercriteria Correlation) is adopted to calculate the objective weights. Based on the theory of cooperative game, the subjective and objective weights are linearly combined into a comprehensive weight. The normal distribution cloud model is introduced as the membership function of the assessment model. By calculating the membership function values of each index, the membership matrices corresponding to different health status levels are constructed. Finally, the real-time operation data of a certain charging equipment is analyzed to verify the feasibility of the assessment model.

Key words: health assessment, analytic hierarchy process(AHP), criteria importance through intercriteria correlation(CRITIC), normal distribution cloud model
