| 摘 要： | 为提高变压器状态评估的准确性，针对传统变压器状态评估方法选取单一指的不足，提出了利用物联网实现多维信息融合的变压器状态参数评估方法。该方法选取常用变压器型式试验参数指标作为在线监测指标，再对指标进行归一化处理。利用物联网对归一化后的指标实现不同指标信息的互联互通，在此基础上利用支持概率改进的DS证据理论对状态指标进行融合，搭建变压器状态参数评估模型。通过实验表明，该方法的状态评估准确性得到很大提升。

| Abstract: | In order to improve the accuracy of transformer condition assessment，a method of transformer condition parameter assessment based on multi-dimensional information fusion using Internet of Things is proposed to overcome the shortcomings of single finger in traditional transformer condition assessment methods.In this method，the parameters of transformer type test are selected as the on-line monitoring indexes，and then the indexes are normalized.The normalized indices are interconnected by the Internet of Things.On this basis，the state indices are fused by the DS evidenceS theory supporting probability improvement，and the state parameter evaluation model of transformer is built.Experiments show that the accuracy of state assessment is greatly improved. |
