DDN在电网调度自动化中的应用

Application of DDN to Electric Grid Dispatching Automation

通信通道是电网调度自动系统中的一个重要环节。通道的质量直接影响到电网调度自动化中综合自动化数据的传输。数字数据网(DigitalDataNetwork)是利用数字信道传输数据信号的数据传输网,利用数字信道传输数据信号与传统的模拟信道相比,具有传输质量高、速度快、带宽利用率高等一系列优点。文章介绍了DDN的技术特点,并结合番禺电网调度自动化的实际情况,阐述了其实现与使用过程中出现的问题。

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.
