电力变压器的状态评估不仅要求智能技术的融合，还应该考虑所有检测状态量之间的相互联系。根据信息数据关联规则和因素空间理论的变权综合概念，提出了一种对电力变压器进行状态评估的方法。通过分析变压器运行中各单项状态量参数与故障类型的关联性，建立综合状态量集合。引入关联规则方法，计算单项状态量的常权重系数；引入具备均衡函数的变权综合模式，计算综合状态量的变权重系数。由此结合既有检测规程，建立了一个较为客观、准确的变压器状态评估体系。运行实例分析表明，该状态评估方法有利于准确地评判电力变压器的真实运行状态。

Condition assessment for power transformer requires not only integrating the known artificial intelligence technologies, but also processing the interrelation of the tested status parameters. According to the association rule of information data and the variable weight synthesizing theory of factor spaces, a condition assessment method of power transf-ormer was proposed in this paper. Via analyzing the interrelation of the independent status parameters and transformer fault types, the set of synthetic status parameters can be built up. Association rule theory was used to calculate the constant weight coefficients of the independent status parameters. The variable weight synthesizing was used for the variable weight coefficients of the synthetic status parameters. Then, combining with the existing maintenance procedures, a preferable condition assessing system of power transformer was proposed. Operational example proved the condition assessing system may reflect the real running condition of power transformer.
