直流输电系统对通信干扰的分析及措施

Communication interference from HVDC transmission system and interference suppression measures

介绍了高压直流输电(HVDC)系统对通信干扰的机理,重点对换流器和输电线路无线电通信干扰的横向衰减与频谱特性、大气条件的影响等进行了较深入的研究,并结合实际高压直流输电工程,提出了具体的抑制干扰的措施。

The mechanism of communication interference from high-voltage direct-current （HVDC） transmission system is analyzed. The transverse attenuation and spectral characteristics of the radio communication interference from converters and transmission lines as well as the influence of atmospheric conditions are emphatically studied. In combination with practical HVDC transmission projects, specific interference suppression measures are presented.
