In the latter, the minimal short transmission path, the length of which is calculated with line impedance, is determined with graph theory to focus on security analysis objects from the whole network to some key transmission lines.

前者根据实时网络拓扑结构和潮流分布状态，在对初始电力网络简化、分区的基础上，利用有向图的邻接矩阵与路径矩阵，通过简单的矩阵运算，快速识别出与过载线路相关的关键输电断面；后者直接利用系统各支路的阻抗，从图论算法的基本思想出发，搜索最易遭受大负荷转移的关键传输路径，从而将安全性分析目标从整个网络缩小到某些关键的输电线路。

An artificial method of constrained coassembling process plan based on VRML model includes setting slide – rotary connection constraint; selecting artificial assembling body model; confirming constraint type of each component to its front or back end component in open or closed loop mechanism; calculating translation and rotary matrix of each component in moving course and its position parameter; generating time – order – path matrix and key frame as per time section; writing each key frame in reverse mode into interpolator of each component VRMC model; adding route in sequence between time and position sensors, position sensor and component form node for generating artificial picture.

本发明属于CAD协同产品设计技术领域，其特征在于：在网络环境下，设计者依托装在节点机上的三维VRML模型，以设计者与设计场景交互方式按照以下步骤实现有约束协同装配工艺规划：设定滑动转动联接约束；选定仿真装配体模型；确定开环或闭环机构中各零部件与它的前端和后端部件的约束类型；计算各零部件在运动过程中的平移和转动矩阵，再根据相应的约束计算运动过程中各零部件的位置参数；再据此生成零部件的时间-顺序-路径矩阵，按时间段形成关键帧；把各关键帧分别以逆序写入VRML各部件模型的插补器，依次在时间传感器和位置传感器之间、位置传感器和零部件造型节点间加入路由，生成仿真画面。
