摘　　要：当前,以太网已成为变电站自动化系统通信的发展方向。文章分析了变电站内网络通信数据类型,论证了基于以太网的变电站自动化系统满足数据实时性的要求,并提出了进一步改进实时性的措施以及如何实现高效可靠的数据传输。通过对传输层协议的分析,在间隔层选择了分组广播模式作为传输模式,UDP作为嵌入式以太网的传输层协议。提出了基于嵌入式以太网的面向超高压变电站自动化系统的通信网络,并做了详细的分析。It is a new trend that applying Ethernet technology as the communication mode in the substation automation system. In this paper, the data type of network service is analyzed; the real - time performance of embedded Ethernet in substation automation is established; the ways to improve real - time performance and how to achieve reliable data transmission. Muhicast is selected as the transport mode and UDP is selected as the transport layer protocol for the embedded Ethernet in bay level.
