【摘要】 研究基于CIM_SVG的电网数据模型基础上的配电线路单线图自动布局算法,给出了一种辐射状单线图自动绘图的完整方案。提出一种馈线分级分支的干线-支路模型,结合CIM_SVG数据模型垂直、水平逐级交叉布置馈线各支线;应用面向对象思想建立一种支线图元区域模型,通过模型数据判别图形中的极不对称支线以及重叠或交叉区域,进而根据判别的结果对图形的整体对称化处理以及重叠或交叉区域的消除,最终完成整条馈线的绘制。最后以10 k V辐射状配电馈线为例对算法进行验证,结果表明算法能在数秒内完成典型配电网络布局,适用于更广泛的配电网可视化分析应用。更多还原

【Abstract】 Based on the CIM_SVG radial distribution feeder, an automatic mapping algorithm is designed in this paper. Firstly, the feeder branches which belong to different levels are preliminarily arranged in vertical and horizontal direction according to CIM_SVG based data.Then, a lever-to-lever trunk-branch model and corresponding branch-regional model which conform the object oriented programming(OOP) are proposed. By utilizing the proposed models, the extremely asymmetrical branches and the overlap/cross regions in the preliminary mapping are identified and eliminated. Finally, a 10 k V radial distribution feeder is taken for mapping as an example to demonstrate and validate the algorithm. The result shows that the proposed algorithm is able to draw the typical distribution network in a few seconds and can be applied to distribution network visual analysis.更多还原
