【摘要】 高压直流(HVDC)输电线路、高压交流(HVAC)输电线路及并行高压交直流输电线路的电磁环境越来越被人们关注。本文基于Deutsch假设,结合实际线路对高压输电线周围电场强度的分布进行了计算研究,完善了空间电力线求取步骤,编写了并行输电线路下的场强的计算程序。程序运行稳定,其有效性通过计算实例得到验证。针对于工程实际,分析了不同的导线高度、极间距、导线半径和不同并行线路布置方式情况下地面电场强度的分布规律。同时分析了并行的高压输电线路对周围环境的影响,并对输电线路的设计提出建议。更多还原

【Abstract】 Electromagnetic environment around HVDC transmission lines, HVAC transmission line and parallel high-voltage HVAC-HVDC transmission line is attracted more and more attention. Based on the Deutsch assumption, the electric field intensity distribution around transmission lines is calculated and analyzed. The solution procedure of electric field line is obtained, and the electric field strength calculation procedures of parallel transmission line are programmed. The procedure runs stability, and its effectiveness has been tested by series of examples. For the actual projects, the ground-level electric field strength distribution regularity with different wires height, space, radius and different arrangement of parallel lines is analyzed. At the same time, the transmission line on the impact of the electromagnetic environment around is analyzed, a number of suggestions on the design of the transmission line are proposed.更多还原
