| 摘 要： | 提出了采用快速独立分量分析(FastICA)的高压直流输电线路(HVDC)单端行波故障测距方法。利用FastICA算法对故障后的直流输电线路电流信号进行处理,分离出电流行波特征信号,检测初始行波波头与第二个行波波头到达测量点的时间,并判断这两个波头的极性关系,实现了故障测距。应用Matlab软件,建立了HVDC系统模型,对多种故障类型进行了故障测距仿真。结果表明,该方法可准确区分中点内外故障,正确有效。

| Abstract: | The single-ended fault location method based on fast independent component analysis (FastICA) is proposed for high voltage direct current (HVDC) transmission system. Using FastICA to analyze the transmission line current signals, the traveling wave feature signal can be extracted; the times of the initial traveling wave head and the second traveling wave head can be estimated, and the polarity relationship between the wave heads is identified, thus realize fault location. The HVDC system model is established by MATLAB, and the simulation of fault location on different faults are made; the results show that this new method can distinguish whether the fault located within half of the transmission line, and this method is reliable and effective. |
