并行交直流输电线路地面场强研究

Research on Ground Field Strength of Parallel AC/DC Lines

特高压输电技术的蓬勃发展为我国电力资源分配和土地利用提供了有利条件。随着交直流特高压输电技术的共同发展,大面积的区域电网将会越发密集,后建设的输电工程会出现大面积地与先建工程共用输电走廊的情况,而该现象可能引起线路之间发生严重的电磁干扰,因此对交直流输电线路地面混合场强的研究具有重要意义。

The vigorous development of UHV transmission technology provides favorable conditions for power resource allocation and land use in China.With the common development of AC/DC UHV transmission technology,the large area of regional power grid will become more and more intensive.The later construction of transmission project will share a large area of transmission corridor with the first construction project,which may cause serious electromagnetic interference between lines.Therefore,the research on ground mixed field strength of AC/DC transmission lines is of great significance.
