摘要(Abstract):

针对电力二次设备传统评估模型存在的评估指标单一、主观性强、评估结果缺乏精准性等问题,提出一种基于数据中台和物元可拓理论的二次设备运行状态综合评估方法。首先,构建二次设备运行状态综合评估指标体系,并基于二次设备评价中心数据中台采集相应的评估指标数据。其次,采用属性层次模型和熵权法分别计算评估指标的权重,经合作博弈模型得到主客观兼具的组合权重。最后,以物元可拓理论为基础构建二次设备运行状态综合评估模型。实例分析表明,该评估方法简单可靠,提高了二次设备状态评估结果的合理性与准确性,可为二次设备的运维检修提供有效助力。
Given the problems of single evaluation index, strong subjectivity and inaccuracy of evaluation results in the traditional evaluation model of power secondary equipment, a comprehensive evaluation method for the operation status of secondary equipment based on data center and matter-element extension theory is proposed. Firstly, the comprehensive evaluation index system of secondary equipment operation status is constructed, and the corresponding evaluation index data is collected based on the data center of secondary equipment evaluation center. Secondly, attribute hierarchy model and entropy weight method are used to calculate the weights of evaluation indexes respectively, and subjective and objective weights are obtained through cooperative game model. Finally, a comprehensive evaluation model of secondary equipment operation state is constructed based on the extension theory of matter element. Example analysis shows that this method is simple and reliable, and it improves the rationality and accuracy of secondary equipment status evaluation results and provides effective support for the operation and maintenance of secondary equipment.
