The equivalent disturbing current, which determines the harmonic interference noise in nearby telephone circuits, is studied systematically.
对衡量直流输电线路电话干扰水平的等效干扰电流标准进行了系统的研究。
As a result, the equivalent disturbing current can meet the requirement with all DC filters in service in any operation mode so that DC system can operate well steadily.
结果表明，任何运行方式下直流滤波器的投运均使线路等效干扰电流基本符合要求，直流系统可维持稳定运行。
At present, the equivalent disturbing current Ieq of transmission line is taken as the index to judge DC filter effect for UHVDC power transmission projects in China.
我国现有特高压直流输电工程均以输电线路等效干扰电流ieq作为直流滤波性能的衡量指标。
