摘　　要：传统变压器经济运行研究大多局限于单个变电站,不适于对地区电网的变压器运行方式进行整体优化。以电网有功电量损耗最小为目标函数,以潮流约束、节点电压约束以及变压器寿命约束等为约束条件,建立了地区电网的多时段变压器经济运行方式优化模型,并采用禁忌搜索算法求解模型。算例结果验证了模型及算法的有效性。Traditional researches on power transformer economic operation are mostly confined to single substation, so the research results are not suitable for overall optimization of operation modes of power transformers in regional power network. Taking minimum active electricity quantity of power grid as objective function and system power flow, nodal voltages and lifetime of transformers as constraint conditions, an optimization model for multi-time interval economic operation of power transformers in regional power network is proposed, and the Tabu search algorithm that possesses stronger search ability is used to solve the model. Results of calculation example show that the proposed model and algorithm are effective.
