中文摘要：

提出一种变压器状态评价的新方法,对提高变压器运行可靠性具有一定的指导意义.首先构建了变压器运行状态的评价指标体系,该体系包括了溶解气体CH4、油介损、绝缘电阻、泄漏电流、吸收比和油中微水等6个评价指标,然后基于变压器在不同运行方式下的运行数据,使用拟态物理学优化算法优化这6个指标的数据,并采用博弈论赋权法确定不同指标的权重值,最终将指标值与权重值进行组合叠加得到变压器运行状态的评价结果.以某市9台大型国产变压器作为仿真案例,基于该案例的实际生产运行数据,算例一验证了拟态物理学算法具有较好的优化效果,能够有效提高收敛速度,并得到更好的迭代结果;算例二实现了最终的变压器运行状态评价,其中9号变压器运行状态最好,3号变压器运行状态最差,这一结果对将来该市变压器的维护和检修具有重要的指导和借鉴价值.

英文摘要：

A new method to evaluate the operating eondition of power transformer is proposed. The method firstly builds an evaluation index system for operation state of transformers, it concludes 6 evaluation indexes, i.e. dissolved gas CH4, oil dielectric loss, insulation resistance, leakage current, oil absorption ratio,and water in the oil. Then operation data are collected based on the different operation modes of the transformer. Artificial Physics Optimization Algorithm is utilized to optimize these multiple index data. Game theory is deployed to ascertain the weight values of different index. Finally the index values and weights are combined to get the evaluating results of the operation condition for transformers. A simulation case is performed based on nine large domestic transformers of one city. Case one verifies that the artificial physics optimization algorithm has better optimization results, effectively improves the convergence speed,and gets better iteration results. Case two achieves the final evaluation of the operation conditions for transformers where No.9 transformer runs best and No.3 transformer runs worst. These results have important guidance and reference value for the maintenance and overhaul of transformers in the future.
