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 ve...
