摘　　要：为避免电力载波线上的噪声干扰对电力系统远程采集造成影响,根据当前电网远程采集工作的实际情况,在总结电力载波线上噪声特性的基础上,提出一种抑制噪声干扰的噪声抑制器。通过对实际电网台区进行测试,对比安装噪声抑制器前后的载波信号波形,验证噪声抑制器的有效性。In order to avoid the influence of noise interference of power carrier cables on remote collection of power system, the article raised noise suppressor of restraining noise interference according to practical situation of present power grid remote collection on the basis of summarizing noise features on power cartier cables. By testing power grid stage in practice, it compared signal carrier wave pattern before and after setting noise suppressor to verify the effectiveness of noise suppressor.
