| Abstract: | A kind of HF protection communication--"transmitting audio protection signal on PLC in multi-purpose mode" is discussed in this paper.Because of increasing shortage of carrier frequency on power network,demand on using channel in multi-purpose mode is increasing strongly.Using PLC to transmit protection signal is an economic and reliable transmission mode,no matter now or in the future.Transmitting audio protection signal on PLC in multi-purpose mode belongs in `edge science'between communication field and protection field and needs engineers of the two fields to make research together. |
