Design and application of substation fault recording and analysis system based on IoT technology

针对变电站智能运维以及故障在线监视的问题,提出了基于物联网架构的变电站故障录波分析系统。分析了智能变电站的基本网络结构,介绍了物联网框架以及物联网监测机制。针对故障录波分析系统提出了系统架构,分析了系统功能、波形采样时间以及录波文件形式等。基于该系统的应用提出了双端测距方法,利用故障录波文件实现故障测距。最后以双端测距为例,说明了所提系统的有效性。

Aiming at the problems of substation intelligent operation and maintenance and fault online monitoring,a substation fault recording and analysis system based on the Internet of Things architecture is proposed.The basic network structure of the smart substation is analyzed,and the framework of the Internet of Things and the monitoring mechanism of the Internet of Things are proposed.Aiming at the fault recording analysis system in this paper,the system architecture is proposed,and the system function,waveform sampling time and recording file form are analyzed.Based on the application of this system,a double-terminal distance measurement method is proposed,and fault distance measurement is realized by using fault recording files.Finally,the effectiveness of the system in this paper is illustrated by taking the double-ended data as an example.
