摘要
导线周围的电磁环境和输电线路的电压等级、回路数、相序等条件息息相关,在进行输电线路设计的时候,需要考虑输电线路附近的电磁环境对周围居民建筑物的影响。利用模拟电荷法等电磁环境计算方法结合输电工程的数据和地形地貌数据计算输电线路导线周围的电磁环境,在三维平台中展示电磁环境曲线,直观反映居民建筑物所处地理位置所受到的电磁环境影响的大小。按照我国针对电磁环境规程规范的相关规定,当房屋在电磁环境影响范围内的时候将予以提示,从而指导输电线路的三维数字化设计。
The surrounding electromagnetic environment of the conductor is closely related to the voltage level, the number of loops, the phase sequence and other conditions of the transmis. sion line. When designing a transmission line, it is necessary to consider the impact of the electromagnetic environment near the transmission line on the surrounding residential buildings. In this paper, the simulated charge method and other electromagnetic environment methods, combined with the terrain data and transmission project data, are used to calculate the surrounding electromagnetic environment of the transmission line with its curve shown on the 3-D platform so that the locations of the resi. dential buildings and the impact of the electromagnetic environ. mental can be visually reflected. According to China’s current standards and regulations with regard to electromagnetic environ. ment, when buildings are within the affected area of the electro. magnetic environment, it should be prompted to guide the threedimensional digital design of transmission lines.
