Research and Implementation of Key Technologies for 3D Visualization of Distribution Network Based on CIM

为满足配电网三维可视化系统对资产数据来源的需求,通过构建核心包、拓扑包中各类数据模型的静态关系,建立了配电网三维可视化系统的CIM模型,并根据空间几何属性将模型的三维信息转化为数据结构,实现了与现有配电管理系统间的信息交互。并针对系统在还原CIM三维模型实际空间位置时精度较低的问题,提出了一种基于模拟退火算法的坐标转换最优参数选择方法,通过对比三种方法的转换误差结果证明了方法的可行性和有效性。最后结合实例展示了配电网三维可视化系统的实际效果和应用功能。

In order to meet the demands of the three -dimensional visualization system, the CIM model of three -di- mensional visualization system for distribution network is established by constructing a static relationship between vari- ous data models in the core package and topological package. According to the geometric properties of the space, the 3D information of the model is transformed into the structure data. Therefore, the information exchange between the ex- isting distribution management systems is realized. Moreover, aiming at the problem of low precision of the system in restoring the spatial position of the 3D model for the CIM component, an optimal parameter selection method based on a simulated annealing algorithm is proposed. The feasibility and effectiveness are proved by comparing the different three methods. Finally, an example is given to show the actual effect and applicability of the three - dimensional visu- alization system.
