摘要
随着电力系统的发展,其接线越来越复杂。目前配电网电气联络图均由人工完成,虽然具备了绘制的灵活性,但由于绘制人员的水平与习惯不同,得到的电气联络图风格也不尽相同,不但效率较低且容易出错,不利于发挥电气联络图在支撑电网建设方面的作用。文中基于配网GIS上的线路图形和拓扑数据,采用线路拓扑结构向正交布局转换的算法,结合树结构自动生成横平竖直、正交布局的单线图。通过设计差异布局方案,建立基于模型驱动的配电网电气联络图自动生成系统架构,实现了电气联络图的自动生成,且当GIS上的电网图形有变化时还可以进行自动更新。以某地10 kV配电网电气联络图的生成作为测试实验,采用文中方法生成的图质量较好,且时间在3 s以内,验证了该方案的实用性。
With the development of power system,its wiring is more and more complex.At present,the electrical contact diagram of distribution network is completed manually.Although it has the flexibility of drawing,due to the different levels and habits of drawing personnel,the electrical contact diagram style is not the same,which is not only low efficiency and easy to make mistakes,which is not conducive to play the role of electrical connection diagram in supporting the construction of power grid.In this paper,based on the line graph and topology data of distribution network GIS,the algorithm of line topology transformation to orthogonal layout is adopted,and the single line diagram of horizontal,vertical and orthogonal layout is automatically generated by combining with tree structure.Through the design of differential layout scheme,the system architecture of automatic generation of electrical contact diagram of distribution network based on model driven is established.The automatic generation of electrical contact diagram is realized,and the automatic update can be completed when the grid graph on GIS changes.Taking the generation of 10 kV distribution network electrical contact diagram of a certain place as the test experiment,the quality of the diagram obtained by this method is better,and the output time is less than 3 s,which verifies the practicability of the scheme.
