摘要: 为获取1 000 kV晋东南—南阳—荆门特高压交流试验示范工程输电线路的电磁环境实际水平,通过对特高压交流输电线路34个环境敏感点、线路跨越公路和铁路、猕猴保护区、转角塔、典型横断面等处的电磁环境指标进行测量,获取了特高压输电线路投运初期的工频电场、磁感应强度、可听噪声和无线电干扰水平,并与控制指标进行了比较。研究表明,1 000 kV晋东南—南阳—荆门特高压交流试验示范输电线路电磁环境水平与500 kV交流输电线路的基本相当,主要指标满足环保批复要求。

Abstract: In order to obtain the actual level of electromagnetic environment on 1 000 kV Jindongnan-Jingmen-Nanyang UHV AC transmission lines in the demonstration project, the indexes of electromagnetic environment along the transmission lines at the early stage of the operation were measured, which include 34 electromagnetic environment-sensitive targets, lines across roads and railways, macaques protection areas, angle towers, typical cross sections and so on. this study compared the measured data of the power frequency electric field, magnetic induction intensity, the level of audible noise and radio interference level with the control indexes. the results show that the level of electromagnetic environment around 1 000 kV Jindongnan-Jingmen-Nanyang lines is basically the similar level to those around 500 kV AC transmission lines which means the main index of electromagnetic environment has met the approval requirements of environmental protection.

Key words: UHV, 1 000 kV AC transmission lines, electromagnetic environment, power frequency electric field, audible noise, radio interference
