基于嵌入式以太网的变电站自动化系统的实现

提出了基于嵌入式以太网的变电站自动化系统通信网络的3种典型应用模式及其适用范围,论述了基于嵌入式以太网的变电站自动化系统中间隔层设备与站控层设备之间的通信宜采用UDP数据报传输层协议的必要性.为了将IEC 60870-5-103应用于变电站内采用以太局域网的情况,给出了基于嵌入式以太网的变电站自动化系统传输协议的有关定义和网络传输要求.文中所提出的通信网络及传输协议已在工程实际中大量应用,取得了良好的效果.

IMPLEMENTATION OF SUBSTATION AUTOMATION SYSTEM BASED ON THE EMBEDDED ETHERNET TECHNIQUE

This paper presents three typical application modes of communication network based on the embedded Ethernet technique for the substation automation system and the related adaptable scope of each mode. The selecting mode of transmission level protocol in the substation automation system based on the embedded Ethernet technique is discussed and it is recommended that UDP be adopted for communication between the station level device and bay level device. In order to use the IEC60870-5-103 protocol in the substation automation system based on the embedded Ethernet technique, the corresponding definition of network transmission protocol and request of network transmission are proposed. The scheme provided in this paper has been verified with good results in many engineering projects.
