摘　　要：在总结以往有关直流输电线路对通信系统影响的研究成果、标准、设计规范基础上,系统考察了我国目前通信网络设备和线路抗干扰能力所能达到的技术水平和所执行标准的现状,并通过理论计算、概率分析和模拟试验,提出了现在通信网能够承受的干扰限制水平,给出了适合当前通信网抗干扰水平的直流等效干扰电流限值建议.On the basis of summarizing bygone research results,standard and design specification related to the influence of high voltage direct current（HVDC） lines on communication networks,the authors systematically investigate the current technical level of counter-interference capability of communication networks and lines in China and present situation of related standards being executed and by means of theoretical calculation,probability analysis and simulation tests;the interference restriction level that the communication networks can withstand is proposed;and the limitation value of DC equivalent disturbing current（EDC） suitable to counter-interference level of current communication networks is given.
