摘要在考虑雷电先导发展的基础上,提出了一种基于希尔伯特-黄变换（HHT）的1 000kV特高压输电线路雷电绕击与反击的识别方法。首先基于ATP-EMTP软件建立了考虑雷电先导发展过程的1 000kV输电线路雷电绕击与反击模型,研究了先导发展对输电线路雷击过电压的影响;然后对雷击输电线路后绕击和反击过电压的暂态过程进行了分析,基于信号的局部特征时间尺度,实现了线路雷电绕、反击信号的经验模式分解（EMD）,对包含大部分高频信号的前四阶固有模式函数（IMF）进行Hilbert变换,将变换后的IMF瞬时幅值作为特征量,并计算其相应的方差贡献率的大小,进而完成输电线路雷电绕击和反击的判别。仿真结果和现场实测数据验证表明,该方法能够正确有效地识别输电线路雷电绕击与反击,不受线路接地电阻和雷电流幅值的影响,且克服了目前雷电流参数实测技术中获取数据工作量大和易误判的缺点,能为输电线路的防雷分析提供理论参考。

Abstract：A HHT (Hilbert-Huang Transform)-based lightning shielding failure and back striking identification method on 1 000kV UHV transmission lines is proposed by considering antecedent development. Firstly, its equivalent model is established by ATP-EMTP based software. The effects of antecedent development on lightning over-voltage on transmission lines are investigated. Furthermore, the transient processes of over-voltages of shielding failure and back striking after lightning transmission lines are also analyzed. The lightning over-voltage signal on transmission line is decomposed by using empirical mode decomposition. Hilbert transformation is conducted on the first four intrinsic mode function which includes majority of high-frequency signal. The transformed instantaneous amplitude of IMF will be chosen as characteristic quantity. Meanwhile, its variance contribution rate will be calculated. In this case, the identification of lightning shielding failure and back striking on transmission lines is realized. The simulation and evaluation of measured data show that the method can effectively identify lightning shielding failure and back striking. It also avoids influence of ground resistance and lightning current amplitude. Meanwhile, the drawbacks in current lightning parameters measurement method, such as large workload to obtain data, easy misjudgment, are overcome in our work. The method provides theoretical reference for analysis of lightning protection on transmission lines.
