摘要
通信网络是变电站自动化系统的关键 ,文中介绍了一种将现场总线技术与以太网技术相结合的通信结构 ,分析了它的优点 ,集中体现在传输实时性、易于与广域网相联、易于与国际标准接轨等几个方面。并且从组网方式、通信规约、软件体系方面分析了其中的通信基本单元的实现方式。
Communication network is a key technique in substation automation system. This paper proposes a network architecture based on the Ethernet and field bus for substation automation system and presents its advantages including real-time performance, easy connection with WAN, easy approach to international standard. And the realization of communication unit is introduced from communication protocol, software structure. Finally, it points out that all the suppliers apply the standard communication protocol should be the most beneficial solution to improve the openness of communication in substation automation system.
