摘　　要：给出了配电网优化决策的数学模型,并开发了图形化的配电网规划计算机辅助决策实验系统。配电所的初始位置通过负荷矩法确定后,采用自动寻优算法确定其最终位置坐标;采用prim算法来优化网架结构;利用经济电流密度法选择导线截面,并采用边际电压费用法加以校验。实验系统以AutoCAD为图形界面,结合数据库系统,实现了数据与图形的联动,方便数据输入和结果查看。The mathematical models for distribution-network optimization and decision-making are given,and a graphical computer-aided decision-making experimental system of distribution network planning is developed.The initial locations of distribution stations are calculated by load-moment method,then using automatic optimization algorithm,the final locations are located.Network topology is optimized by the prim algorithm.Using economic current density method,the conductor cross-sections are selected,which are checked by marginal voltage cost method.Based on AutoCAD as the graphical interface,the system ties data with graphic,which is convenient for data input and results show.
