【摘要】：GIS变电站在我国电力市场的发展中日益增多，由于GIS设备故障后检修时间长，技术难度大，所以针对GIS的局部放电在线监测技术的应用研究具有重要的实际意义。 论文首先对GIS局部放电的类型和特点以及目前GIS局部放电在线监测技术进行了分析比较，根据保定地区电网的实际情况，提出了将基于特高频（UHF）技术的GIS局部放电在线监测系统应用于保定地区电网GIS局部放电在线监测，并完成了硬件设计和软件开发。基于UHF的GIS局部在线监测系统是在组合电器的外部盆式绝缘子上安装UHF传感器，，通过传感器收集设备内部的电磁波信号，通过信号光缆传输到监测系统，并通过网线与变电站内其他设备实现通讯，经电网的通信网络可将数据传送到远方监测点，然后利用收集到的监测数据对GIS局部放电情况进行分析。最后依据现场实例进行分析，说明了基于UHF的GIS局部放电在线监测系统的有效性，基于UHF的GIS局部放电在线监测系统的应用对提升保定地区电网的可靠性有重大帮助。
[Abstract]:GIS substation is increasing in the development of electric power market in our country. Because of the long time of overhaul after the failure of GIS equipment and the difficulty of technology, it is of great practical significance to study the application of partial discharge on-line monitoring technology for GIS. Firstly, this paper analyzes and compares the types and characteristics of GIS partial discharge and the current GIS partial discharge on-line monitoring technology, according to the actual situation of Baoding power network. A GIS partial discharge on-line monitoring system based on UHF (UHF) technology is proposed in this paper, and the hardware design and software development are completed. The GIS local on-line monitoring system based on UHF is to install the UHF sensor on the external basin insulator of the combined electrical apparatus, collect the electromagnetic wave signal inside the equipment through the sensor, and transmit it to the monitoring system through the signal optical cable. The data can be transmitted to remote monitoring points through the communication network of the power network, and then the partial discharge of GIS can be analyzed by using the collected monitoring data. Finally, the effectiveness of the GIS partial discharge on-line monitoring system based on UHF is analyzed according to the field examples. The application of the GIS partial discharge on-line monitoring system based on UHF is of great help to improve the reliability of Baoding power network.
