摘　　要：从调度通信网的特点出发，介绍了利用调度通信通道传送高频保护信号的基本原理和实现方法。采用调度通信通道实现高频保护信号的传送，将会大大提高高频保护的信号传输可靠性，并有可能扩大高频保护的应用范围。Based on the characteristics of dispatching and communication network,the basic principle and method for realizing high frequency protection signal transmission by dispatching and communication channel are introduced.The analysis shows that by using dispatching and communication channel,the transmission reliability of high frequency protection signal will be increased greatly,and the application of high frequency protection will be extended too.
