| Abstract: | The communication channel is an important part of electric grid dispatching automation. The quality of communication channel directly affects the data transmission. Digital Data Network is a data transmission network by using digital channel. By contrast with analog channel, it has some strongpoint, such as higher transmission quality, greater speed, better utilization factor of bandwidth and so on. This article introduces the technology characteristics of DDN, and expatiates its realization and the problems in the practical situation of Panyu electric grid dispatching automation. |
