基于频率-相位分析技术的特高压输电线路故障位置精密标定的基础研究

The study for precise trouble location of UHVDC transmit electricity line on frequency-phase analysis

故障波形在特高压输电线路传输中的衰减和畸变,是时间差法故障定位误差的主要原因。为解决这个问题,提出一个新的方案,即频率-相位分析技术的长距离超高压输电线路故障定位,并通过比较实验来说明其定位的准确及先进性。

The attenuation and aberration of fault waveform in UHVDC transmission is the main cause to lead to the error of fault location based on time difference method. In order to resolve this question, this paper gives a new approach, power line fault location based on frequency-phase analysis, and illuminates that it＇s more advance and more precise than other methods by experiment.
