摘要
输电塔结构的结构损伤检测是电力线路正常运行的重要保障手段,通过基于时间序列分析AR-MA模型阐述了输电塔结构损伤预警的时间序列方法,并基于神经网络分析方法给出了输电塔结构损伤预警的处理步骤,从而可以有效地实现结构损伤评估。500kV输电塔结构损伤评估算例表明,提出的损伤评估方法对结构损伤具有敏感性,具备实时在线损伤预警的应用价值。
The transmission tower structure damage examination is important safeguard method of power line. This article analyzed the structure damage method based on ARMA model. The warning processing step of tower structure damage was given based on neural network analysis method in this paper, thus the structure damage might be appraised effectively. The 500 kV transmission tower structure damage appraisal example indicats that the damage appraisal method is sensitivity to the structure damage, which has the real-time online damage early warning application value.
