摘　　要：变电所供电半径的选择是一个复杂的问题。为了确定最佳供电半径 ,减少投资 ,降低损耗 ,建立了Fuzzy环境下的变电所供电半径选择的几何规划模型。它包括软约束问题和含Fuzzy系数的问题。通过数值实例的计算 ,验证所建立的模型 ,与静态和动态的优化数学模型如控制模型和经典几何规划模型相比较 ,包含更多的信息 。The choice of power supply radius for transformer substations is a complicated problem.A fuzzy geometric programming model of power supply radius under the fuzzy environment, including problems of soft constraints and fuzzy functions with fuzzy coefficients,is built in order to determine the best choice with less investment and lower energy loss. From the model built in this paper more information can be collected and more satisfactory results can be obtained compared with other static and dynamic optimum mathematical models such as controlling models and classical geometric programming ones.
