网络时代的变电站自动化

Substation automation in the times of network

回顾远动信息传输的发展过程,指出变电站自动化纳入数据通信网是今后研究的主要课题之一。论述TCP/IP协议转换器模式和应用层协议模式及其在已建站和新建站中的应用。指出网络通信将极大提高信息传输速率,从而满足EMS应用软件对实时数据的更高要求,从根本上解决远动信息一发多收和多级转发问题。

Th e development process about the transmission of telecontrol message is reviewe d,it is indicated that the one of the impor-tant topics for the future study is substation automation tending to wide area network.The paper discusses TCP/ IP protocol transducer mode and application layer protocol mode and their applic ation in substation.In addition,it is also pointed that the transmission rate of mes-sage will be promoted rapidly via network communication,therefore,reac hed the requirements of real-time data for EMS application soft-ware.Thus,th e problem of telecontrol message transferring and communication with the point to multi-point mode will be solved basically.
