摘　　要：介绍了双向工频通信的基本原理,建立了一简单的信号传输模型。从暂态电压和电流在配电网中传播的角度,分析了双向工频通信信号在配电网中的传输特性。通过实际测试数据,验证了双向工频通信方式具有抗干扰能力强、不受线路状况和负荷变化制约的特点。The principle of the Two-way Power Frequency Automatic Communication System (TWACS) is described and its simple model of signal transmission is presented. From the viewpoint of propagation of transient voltage and current in distribution network, the transfer characteristics of two-way power frequency signals in distribution network are analyzed. Through data from practical testing the features of the high counter-interference capability and not to be restricted by the situation of transmission lines are verified.
