摘要
介绍了直流输电线路对电信线路干扰影响各分量的特点,根据当前输电线路和电信线路的运行方式、电气特性特点,对各分量进行了简化或取舍,提出采用等效干扰电流法进行工程评估,计算噪声计电动势,干扰影响计算公式不需考虑衰减系数。计算结果为正在编制的电力行业标准DL/T5340《直流输电线路对电信线路影响防护设计规定》提供了依据。
The characteristics of interference effect components of DC power transmission lines on telecommunication lines are discussed. Based on the current working mode and electrical features of power transmission lines and telecommunication lines, the equivalent disturbing current method is recommended for the project evaluation of noise meter＇s electromotive force, by simplifying or neglecting some components. The calculation formula of interference effect doesn＇t need to consider the attenuation coefficient. The research results could provide a basis for the compiling of the power industrial standard DL/T 5340 ＂Technical code for designing of telecommunication lines against danger effects from DC power transmission lines.＂
