摘　　要：讨论了高频保护通信的一种方式：“电力线载波音频复用保护”。在电网载波频率日益紧张的今天，复用通道的要求越来越强烈，利用电力线载波传输继电保护信号，不论现在还是将来都是一种经济可靠的传输方式，而载波音频复用保护信号属于通信专业与保护专业的“边缘科学”，需要二个专业的人员共同研究探索。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.
