摘　　要：为解决输电网潮流图自动生成中厂站布局与线路布线问题,提出基于动态平衡布局的输电网潮流图自动生成方法。针对厂站布局,首先,在力导向算法的基础上引入基于图纸中心点的惩罚函数,以解决力导向算法布局不均匀的问题,提高布局的均布度;然后,利用厂站分布率参数控制算法平衡次数,引导厂站向图纸边界运动,解决布局自动适应给定图幅大小的问题;最后,通过位置映射变换将围绕图纸中心点的椭圆分布转换为矩形分布,解决引入惩罚函数布局均匀但不符合传统输电网潮流图绘制习惯的问题。针对线路布线提出以构建通道树为中心的布线方法,有效降低布线交点个数,提升布线效果。所提布局与布线算法在实际工程应用中取得了良好的效果,通过案例验证了输电网潮流图自动生成的正确性和有效性。In order to solve the problems of factory station layout and line routing in automatic generation of power flow diagrams of transmission networks,an automatic generation method for power flow diagram of transmission network based on dynamic balance layout is proposed.For factory station layout,first,a penalty function based on the center point of the drawing is introduced on the basis of force-directed algorithm to solve the problem of uneven layout in the force-directed algorithm and improve the uniformity of the layout.Then,the distribution rate parameters of the factory stations are used to control the times of the algorithm balance,guiding the factory stations to move towards the boundary of the drawing,and solving the problem of the layout automatically adapting to the given drawing size.Finally,the elliptical distribution around the center point of the drawing is transformed into a rectangular distribution through position mapping transformation,solving the problem of introducing the penalty function layout that is uniform but does not conform to the traditional habit of drawing power flow diagrams of transmission networks.A routing method centered on constructing a channel tree is proposed for line routing,effectively reducing the number of routing intersections and improving the routing effect.The proposed layout and routing algorithm achieves good results in practical engineering applications,and case studies validate the correctness and effectiveness of the automatic generation method for power flow diagrams of transmission networks.
