基于地理信息的输电网单线图自动生成新算法

Application of Geographic Information in Automatic Generation of Single-Line Diagrams for Power Transmission Networks

提出一种基于地理信息的输电网单线图自动生成新方法,该方法在电网节点布局问题的一般数学模型中引入了关键节点的地理信息,先采用带约束的罚函数法求得单线图节点的初始布局,然后对初始布局进行优化得到最终布局。新方法仅用少量关键节点的地理信息即可实现电网节点的自动排布,不仅改善了单线图自动生成算法的性能,而且节点排布结果美观清晰,更符合调度员的使用习惯。算例测试表明了新方法的有效性。

A new geographic information based on method to automatically generate single-line diagrams is presented. In this method, the geographic information of key nodes is lead into the general mathematical model of the node layout problem, firstly, by use of penalty function with constraints the initial layout of nodes in single-line diagram is obtained, then the initial layout is optimized to obtain final layout. Only using the geographic information of few key nodes, the automatic node placement of power network can be implemented, and it not only improves the performance of automatic generation algorithm for single-line diagram, but also the node placement is elegant and clear and more suitable for dispatchers. The effectiveness of the proposed method is verified by testing system.
