摘　　要：考虑变压器的经济性,建立变压器年运行费用数学模型,以变压器的电能损耗费用、基本电费以及设备投资折旧和维护费用最小为目标函数,基于不同类型建筑物的负荷曲线,采用遗传算法对模型进行求解,得到建筑物所选变压器的台数和容量。通过对具体实例进行分析,验证了上述模型的准确性和求解算法的有效性。Considering the economy of transformer,a mathematical model of annual operating cost is established.With the minimum electric energy loss costs, basic power charges of transformer, depreciation expense of equipment investment and maintenance costs as the objective function, based on load curve of different types of buildings, a genetic algorithm is developed to work out the number and relative capacity of transformers in the building. Through the analyses of examples, the accuracy of the above model and the effectiveness of the algo rithm have been verified.
