嵌入式以太网通信技术及其在中低压微机保护测控装置中的应用研究

随着计算机技术以及网络通信技术的发展,许多新技术在变电站系统中开始应用,变电站自动化系统得到了快速的发展。本论文主要就基于嵌入式以太网通信技术的中低压微机保护测控装置的设计及相关的网络通信技术展开探讨和研究。 文章首先分析了变电站自动化系统的发展情况,对变电站数据通信系统的现状和存在的问题进行了总结和描述。由此文章提出要在变电站自动化系统中应用Web服务器技术,并介绍了其应用情况。在此基础之上,文章提出了网络型变电站自动化系统中间隔层设备应具备的功能。 其次,论文在详细研究网络型变电站自动化数据通信系统的相关技术、分析在变电站自动化系统中应用Web服务器的意义和具体的应用方法的基础之上,文章对应用嵌入式以太网通信技术的微机保护测控装置进行了总体设计,并对其具体应用的中低压场合变电站自动化系统做了方案配置。 按照这种总体设计思想,文章一方面详细设计了基于DSP平台的网络式微机保护测控装置,重点介绍其通信模块的具体设计和调试方法。在详细分析IEC 60870-5-103规约运行机制的基础上,论文具体介绍IEC 60870-5-103规约在基于该DSP平台的微机备自投装置上的实现方法,及其通信程序设计。 另一方面,文章在深入研究嵌入式Web服务器技术的基础上,设计了一个微型嵌入式Web服务器模块。论文详细介绍了其软硬件体系的实现方法和工作原理。作为微机保护测控装置的Web服务模块,论文应用该微型嵌入式Web服务器模块实现了微机备自投装置的远程浏览功能。 最后,文章对整个课题作了总结,并对所研究的内容进行了展望。
