摘　　要：随着嵌入式技术和网络技术的发展,基于现场总线的传统电力监控系统所具有的组网规模小、子网分散、传输距离短等缺点日益明显。为了克服传统现场总线技术的固有缺点,利用网络技术和嵌入式技术的优势,并基于以太网技术和IEC 60870-5-104规约,提出了一套可以监测整个矿区电力接地故障的监控系统设计方案。试验结果证明,该系统可实现电力系统接地故障检测所要求的全部功能。Along with the development of embedded technology and network technology, the disadvantages of traditional power monitoring system based on fieldbus become increasingly evidence, e. g. , small networking scale, dispersed subnets, and short transmission distance, etc. In order to overcome these inherent defects of traditional fieldbus technology, by adopting the superiority of network technology and embedded technology, the design scheme of grounding fault monitoring system based on Ethernet technology and IEC 60870-5-104 for entire coal mining area is proposed. The experimental result shows that all the functions required for grounding fault detection of the electric power system can be accomplished.
