摘要

气体绝缘变电站的不同缺陷导致不同类型的局部放电。本文介绍了一种新的用于GIS的PD在线监测技术。采用外接传感器检测PD信号，具有较宽的频带。PD信号采集采用两种测量方法，并采用高性能硬件单元，以反映真实的PD特性。基于统计分析与高频分析相结合的思想，提高了分析水平。所开发的PD在线监测系统已在某110 kV GIS变电站运行。结果表明，该系统是有效的

Development and application of a novel partial discharge on-line monitoring system for GIS

Different defects in gas insulation substation (GIS) cause several types of partial discharge (PD). A novel on-line PD monitoring technique for GIS is described in this paper. An external sensor is adopted to detect the PD signal and has a wide frequency band. Two kinds of measurement method are used for PD signal acquisition, and high performance hardware units are also employed in order to reflect the true PD characteristics. Based on the idea of combining statistical analysis and high frequency analysis, the analysis level is improved. The developed PD on-line monitoring system has been operating at one 110 kV GIS substation. The results show that the system is effective
