750 kV智能变电站三维数字化设计研究

Research on 3D Digitizing Design of 750 kV Intelligent Substation

传统二维设计模式难以满足国网公司输变电工程设计精细化和信息化的要求,而三维数字化设计系统先进的设计理念、强大的数据库功能契合了智能电网的发展需求,并在电网建设中得到了广泛的应用和发展。通过对某750 kV变电站三维数字化设计,实现了三维数字化变电站的建模、工程量自动统计、三维漫游等功能,并基于数字化三维软件对所建变电站进行了碰撞检查,最后对设计要点进行了分析总结。

As it is difficult for the traditional two-dimensional design pattern to meet the requirement for refinement and informationization of power transmission and transformation engineering design of SGC, 3D digitizing design system is proposed as a newgeneration of design pattern in recent years due toits advanced design concepts and powerful database and it has been widely used in the power grid construction and development.In this paper, a 3D digitizing design ofa 750 kV substation is carried out, which realized the modeling, automatic calculation of engineering quantity,3 D roaming etc. of 3D digitizing substation. And based on the 3D digitizing software, the collision check, the safety net distance calibration and wire stress calculation etc. ofthe substation built are carried out, and finallythe keydesign points are analyzed and summarized.
