摘要
快速建立输电塔架三维仿真模型对电网安全运行与信息管理有重要作用。根据输电塔架的结构特点及结构相似性进行模块化划分,并用参数化方法为相同结构型式的模块建立原始三维模型;在此基础上根据塔架型号与呼高,对各模块进行选择与组装,赋值参数驱动各模块的原始模型,实现各种塔型与呼高的塔架三维快速建模。以某酒杯型直线塔为例,输入塔架型号与呼高即实现其三维模型快速建立,验证了该参数化三维建模方法的正确性与实用性。
Establishing three-dimensional simulation models of transmission towers rapidly is important for information management and analysis of the power grid. According to the structural characteristics of transmission towers, the tower is divided into several modules which have the similarity structure, and each module corresponds to a parametric three-dimensional model. Then modules are selected and assembled based on the type of tower and nominal height. By importing the parameters of modules into their parametric models, the three-dimensional model of various types and nominal heights of transmission towers can be completed quickly. Finally, the top structure of a cup shaped power transmission tower is used as an example to demonstrate this method. The 3D model can be established immediately only by inputting the type and nominal height of transmission tower. It is indicated that the parametric 3D modeling method for transmission towers is correct and practical.
