摘　　要：文章指出间谐波对工频双向通信信号检测有很大影响,间谐波是配电网工频双向通信最大的干扰源;提出并推导了间谐波对通信信号的作用机理公式;研究了间谐波特别是配电网很容易发生的分频谐振产生的信号检测误差范围;指出了在线监测间谐波对双向工频通信信号检测具有十分重要的意义。Inter-harmonics can affect the detection of bidirectional power frequency signal. This paper introduces the formula of inter-harmonic on signals, and discusses the range of signal detection error caused by inter-harmonics that are easily found in power distribution network. It points out that the on-line monitoring on inter-harmonics, especially the subharmonie resonance is very important for the signal detection.
