配电网均匀接线图生成及态势图察觉度计算

Generation of Uniformly-distributed Distribution Network Connection Diagram and Perception Measurement for Situation Awareness Diagram

针对常规配电网接线图作为配电网态势可视化态势底图存在不少缺陷,文中提出了一种全新的底图形式,即以变电站为中心的配电网动态辐射状均匀接线图的态势底图,并提出了其基于改进型F&R力导布局的自动生成算法,即针对过长馈线在节点运动方程引入牵引力,添加点边规避处理负荷与线路过近的问题,引入馈线与馈线、相邻级别线路的斥力从而达到边边规避;基于地理接线图和均匀接线图为底图的2种电压等高线态势图进行定性分析,提出了态势图察觉度及其计算方法,并进行了定量对比,表明后者的态势察觉度明显优于前者。

A novel substation-centralized uniformly-distributed distribution network one-line diagram is put forward to overcome many shortcomings of regular distribution network diagrams in situation awareness visualization.An improved F&R force-direction algorithm is developed to automatically generate such a diagram,which introduces traction force to shorten the long lines,the pull force to avoid the load being too close to the nearby lines,and the pull force to avoid the closeness between the nearby feeders and the section lines.Based on a qualitative analysis of situation visualization performance of the geographical connection diagram and uniformly-distributed connection diagram,an evaluation method for performance of situation awareness is put forward and the numerical calculation has been applied for those base diagram schemes,the numerical results showing that the situation visualization performance based on the uniformly-distributed connection diagram is evidently much better than what is based on the geographical connection diagram.
