摘　　要：通过对运行变压器温升极限要求的分析,同时研究变压器在运行过程中的功率损耗及冷却装置功率投入。根据变压器绕组直流电阻的温度特性,分析计算冷却装置功率投入与变压器功率损耗降低之间的内在联系,进而提出变压器冷却装置的智能控制策略。合理投入冷却装置功率,既保证变压器在电力网中安全可靠运行,又可以使运行变压器和冷却装置消耗的功率之和达到最低,实现电力变压器整体经济运行和节能降损的目的。Through the analysis of the temperature limit re- quirements of operation transformer, then study the power loss and the cooling device power input in the process of operation transformer.According to the temperature characteristic of transformer wind- ing resistance, analysis and calculation the cooling device power input and the transformer power loss- es, put forward the intelligent control strategy of transformer cooling device. Investing reasonable cooling device power, not only ensure transformer operation safely and reliably in the power grids, and also ensure the gross power consumption of transformer and cooling device up to the minimum, realize the overall economic operation of power transformer and the purpose of saving energy loss reduction.
