摘要
在研究嵌入式实时操作系统Nucleus的基础上,构建了以MC68332为CPU,CS8900 A为以太网控制器的智能电气设备以太网接入模块,分析了现有通信协议IEC60870-5-103的实现,提出以此作为变电站间隔层通信接口的变电站自动化系统通信方案。该方案能够提高现有变电站自动化系统通信的速度和可靠性,并能升级成符合IEC6I850体系的变电站自动化通信系统,为解决变电站内设备自我描述和通信接口无缝链接等问题提供了软硬平台。
Nucleus is an embedded operating system developed for micro- controller. Its application in a high performance yet low cost Ethemet interface is designed, which is based on MC68332 CPU and C88900A Ethemet controller. Then the Ethemet scheme of substation automation system is presented, using the Ethernet interface for bay level. The Ethernet scheme can improve the speed and reliability of communication. Software upgraded in the future, the Ethemet scheme can fulfill the requirement of IEC61850. The plat of hard and soft is designed for solving device description and the seamless communication.
