摘要
文中针对GIS设备运行状态在线监测进行研究,完成了基于PIC32MX795和AT91SAM9G20(ARM9核心)高性能嵌入式处理器的高压开关运行状态在线监测仪的研制,实现对GIS的机械特性参数、GIS气室中SF6的密度、微水含量、放电情况的实时监测、录波分析等功能;针对国家对智能电网的要求,支持国际电工委员会提出的IEC61850标准和双网络接口冗余设计,提高网络容错能力和运行可靠性。
This paper researched on the GIS equipment on-line monitoring. The paper designed a high-voltage switch on-line monitor based on high-performance embedded processor PIC32MX795 and AT91SAM9G20 （ARM9 core）. It realized the mechanical parameters of GIS, SF6 gas density, SF6 gas micro-water content, and the real-time monitoring of part discharge, as well as the waveform recording and analysis functions. According to the national smart grid requirements, the design followes the international electrotechnical commission＇s IEC61850 standard protocol and dual redundant network interface design. It improves the network reliability and fault tolerance.
