摘　　要：在深入分析配电网设备上加装的各类传感器装置中数据获取情况的基础之上,综合考虑设备的能效影响因素,构建了基于传感器数据的配电网设备能效评估指标体系。根据每个指标在节能潜力、成本和难度方面对配电网设备能效的影响程度不同,构建了递阶层次结构模型,并采用层次分析法(AHP)进行指标权值计算。根据定量指标易于量化的特征,构建了对标函数,完成了定量指标能效指数的计算。从而实现对配电网设备的能效评估。并以某实际的配电变压器算例验证了所提方法的实用性和有效性。On the basis of in-depth analysis on data acquisition condition in all kinds of sensor device of distribution network equipment,comprehensively considering the influence factors of energy efficiency of the equipment,the index system of energy efficiency evaluation of distribution network equipment is established.According to each index has different energy efficiency influence degree on the distribution network equipment in the energy saving potential,cost and difficulty aspects,hierarchical structure model is established,and the analytic hierarchy process（ AHP） is used to calculate index weights. According to the characteristics of the quantitative indicators,which are easy to quantify,the benchmarking function is established,the energy efficiency index calculation of quantitative indicators is completed. Thus,energy efficiency evaluation for distribution network equipment is achieved. And an actual distribution transformer example is taken to verify the practicability and effectiveness of the proposed method.
