摘　　要：提出了一种输电网单线图自生成的改进算法,完善了节点布局的数学模型,引入多目标以及分区约束项,提出了一种适合求解该优化问题的遗传算法,并设计了相应的交叉和变异算子。提出了走线过程中局部优化算法,减少了线路之间的交叉。基于上述算法,搭建了以CIM/SVG作为输入输出模式的图形系统,具有良好的交互性和兼容性。对某实际电网进行了单线图自动生成,计算效率和图形效果都满足工程实用的要求。An improved method for automatically generating one-line diagrams is presented. The model of stations＇ layout is improved by adding multiple objects and constraints. A genetic algorithm which is suited to solve this problem is designed. Crossover operation and mutation operation in the genetic algorithm make the result satisfy constraints naturally. Local optimization algorithms are used to reduce crossovers among lines. Based on the algorithms above, a graphic system is built using CIM/SVG mode as the input-output mode, which makes the system interactive and compatible. The application result of a real power grid network makes it clear that computing efficiency and graphic effect are good enough for engineering applications.
