基于赋权与加权秩和比的变电设备 状态评价

随着变电站设备智能化和自动化的快速发展，变电设备的多样性和繁杂性呈现出日益增加的趋势。这给基层人员开展设备状态分析带来了巨大的压力。传统设备评价的方式多为根据设备的运行时间及故障情况，结合工作经验进行评价分析，评价结果存在主观性。为了对设备的运行状态做出精准的评估，我们提出一种基于赋权与加权秩和比的设备状态评估方法。首先，针对设备运行中的大量参数数据进行选择，构建评估指标体系；接着，采取熵权法确定各指标的权重系数；然后，通过引入秩和比与权重相结合，构成加权秩和比；最后，实现对变电设备运行状态的综合评估。通过对实际运行的设备进行验证分析，并对结果进行一致性校验，本文提出的设备状态分析方法得到了验证，证明其具有合理性和可行性。这一方法对于加强设备的科学、精准评估具有一定的推广应用价值。

Status Evaluation of Substation Equipment Based on Weighting and Weighted Rank Sum Ratio

With the rapid development of substation intelligence and automation, the diversity and complexity of substation equipment is increasing, which brings enormous pressure to grassroots personnel to conduct equipment status analysis. The traditional method of equipment evaluation is mostly based on the operating time and fault conditions of the equipment, combined with work experience for evaluation and analysis, and the results are subjective. In order to accurately evaluate the operation status of equipment, a method of equipment status evaluation based on weighted and weighted rank sum ratio is proposed. The first step is to select a large number of parameter data during equipment operation, construct an evaluation index system, adopt the entropy weight method to determine the weight coefficient of each index, and combine the rank sum ratio and weight to form a weighted rank sum ratio to achieve a comprehensive evaluation of the operation status of substation equipment. The rationality and feasibility of the method proposed in this article have been verified through verification and analysis of actual operating equipment and consistency verification of the results, which has certain promotion and application value for strengthening the scientific and accurate evaluation of equipment.
