摘要
分析了以太网两种常见的通信技术应用模式:基于数据链路层的应用及基于IP层的TCP/UDP传输方式应用,比较了他们之间的差别,给出了各自的应用场合,并针对变电站自动化系统的主要业务进行了通信层面的业务分析,结合CBZ-8000A系统中IEC 60870-104及IEC 60870-103/TCP的通讯网络技术应用情况进行了具体说明,对数字化、智能化变电站围绕IEC 61850的通讯技术发展方向进行了探讨。
This paper analyzes the two common Ethernet communication technology application modes,one is based on data link layer,and the other is based on TCP/UDP transmission mechanism in IP layer.The paper compares the differences between them,and gives their respective application situation,and conducts an analysis of substation automation system＇s primary business in view of communication business combining with the application of IEC 60870-104 and IEC60870-103/TCP network technology of CBZ-8000A system.Finally,the development trend of digital and smart substation communications technology such as IEC 61850 is also discussed.
