摘要
当前数字化变电站和智能电网的发展对RTU性能提出了更高的要求。基于此,本文介绍一种采用ARM7TDMI(-S)芯片LPC2294,结合μC/OS-Ⅱ操作系统,兼容多种通信方式,具有多功能、多种规约库的数字化RTU设计。详细介绍了其硬件电路设计方案、通信接口设计和软件程序设计流程;并着重讨论了利用南京南自科技发展有限公司103规约通信的实现方法,最后提出进一步的功能扩展,以满足数字化变电站和智能电网的要求。
At present, because of the digital substation and smart grid development, the requirement on performance of RTU must be more and higher. Thus the design of RTU based on ARM7TDMI （-S） chip has been discussed. This RTU using μC/OS-Ⅱ has kinds of communication interfaces and multi protocols. The hardware and software design of 2294 has been introduced in detail. The communication method by the 103 Protocol taken by the SAC has been emphatically discussed. At last the future programs for providing more functions so that it can satisfy the requirement of the digital and smart grid has been given.
