摘　　要：寻求一种新的最佳供电半径计算方法,加入了对供电可靠性的考虑,通过研究两者关系建立数学表达式,以经济成本为优化目标,单位面积供电年费用最小为目标函数,将可靠性与传统的电网供电能力、电压质量、以及线损率等一同作为约束条件,利用单纯形与粒子群优化相混合的算法求对最佳供电半径做出优化,并通过具体算例分析得出不同供电可靠性要求下的供电半径计算结果与经济成本比对,证明了该方法的可行性并具有一定的应用价值。This paper seeks a new method of calculating the optimum power supply radius,consider adding a power supply reliability through research to establish the relationship between mathematical expression to the economic cost optimization objectives,annual cost of power per unit area as the objective function,the traditional power grid reliability and capacity,voltage quality,as well as along the line loss rate constraints,the use of a simple shape and particle swarm optimization algorithm for mixed radius make for optimal power optimization and analysis obtained through specific examples the radius of the power supply reliability requirements under different calculation results and economic cost comparison,proved the feasibility of this method and has a certain value.
