摘要
我国大力发展输电线路规模,其中特高压输电线路比例显著增加,线路的雷击事故也随着增加。笔者开展雷击暂态响应监测技术研究,提出了较为精确的故障定位技术和故障识别技术,通过理论分析对测量结果进行修正;研发了雷击暂态响应监测系统,通过理论分析得出监测终端的安装距离;通过现场示范应用,结合人工巡检等手段进行校验,对该监测系统的故障精确定位误差和故障识别能力进行了论证,为进一步深入研究输电线路雷击机理和针对性反措奠定基础。
China has made great efforts to develop the UHV transmission lines,and the lightning strike accidents of lines have also increased. Research on lightning transient response monitoring technology has been made. A more accurate fault location and fault identification technique is proposed,and the measured results are corrected by theoretical analysis. The lightning transient response monitoring system is developed,and the installation distance of the monitoring terminal is obtained by the theoreticalanalysis.By means of field demonstration application and manual inspection,the fault location error and the identification rate of lightning trip for the monitoring system are demonstrated,which lays a foundation for further research on the lightning strike mechanism of transmission lines and targeted countermeasures.
