摘要
以太网由于其介质访问控制采用载波侦听多路访问/冲突检测的机制,对其能否应用于变电站自动化系统,究竟采用何种模式,在实践中一直有不同看法。文章在分析了嵌入式以太网技术应用于变电站内通信系统可行性的基础上,研究了其具体的应用模式,并从硬件平台和软件实现方面阐述了嵌入式以太网实现的关键技术,最后指出了实现过程中应注意的问题。
Different opinions still exist in practice, whether the Ethernet could be applied to Substation Automation System (SAS) and what kind should be adopted, as for Ethernet, the mechanism of Carrier Sense Multiple Access/Collision Detection (CSMA/CD) is used in medium access control. On the basis of analyzing the feasibility of applying embedded Ethernet technology to the communication system in substations in detail the concrete application mode is studied. The key technical problems of realizing the application of embedded Ethernet to communication system in substations are expounded in respect of hardware design and software programming. The relevant problems which should pay attention to in its implementation are pointed out.
