摘要
针对当前变电站自动化系统中通信网络的特点,依托于实际的大型变电站自动化系统开发项目,着眼于以太网上不同协议和传输机制对数据传输的实时性、可靠性会产生不同的效果。首先分析了工业以太网在当前新兴的两层式变电站体统应用的缺陷,提出了组播技术、UDP扩展协议在工业以太网中的应用策略,以及实现中的关键技术。
Applying Ethemet technology in substation communication system is a trend. According to the features of communication network for Substation Automation System（SAS） as well as the experience of large transformer station automation systems in real development projects, this paper analyzes the disadvantages of industrial Ethernet used in 2-layers SAS, proposes a new solution of the 2-layers SAS based on multicast technology and UDP extended protocol.
