摘要
光伏场站的运行环境较为恶劣且光伏集电线路结构复杂,导致了集电线路故障频发,从行波电流和行波法故障测距介绍入手,对光伏集电线路极易发生的故障的行波电流特征进行研究,将高发类故障行波电流特征进行分类,并提出故障行波电流特征提取算法,以便于光伏集电线路再次发生故障时,可利用算法快速识别故障原因,保障线路稳定运行.
Abstract
The operating environment of photovoltaic power stations is relatively harsh and of the profound structure of photovoltaic collection lines,leading to frequent faults in collection lines.Starting with the introduction of traveling wave current and traveling wave method-based fault location,studies are conducted on the traveling wave current characteristics of faults that are prone to occur in photovoltaic collection lines.The traveling wave current characteristics of successive faults are classified,and an algorithm for extracting the traveling wave current characteristics of faults is proposed for quickly identifying the causes of faults when photovoltaic collection lines fail again so as to ensure the stable operation of the lines.
