Study on Wind Bias of Transmission Line Insulator Conductor Coupling Model under Fluctuating Wind

研究脉动风作用对输电输电线路绝缘子—导线耦合模型风偏的影响。首先选取了实际线路较为常见的5种档距下的输电线路进行了脉动风场的模拟,模拟出的不同档距下距离导线原点50 m处的脉动风速时程及其对应的目标谱和模拟谱的吻合曲线,然后建立输电线—绝缘子耦合模型,计算出脉动风作用下导线非同期摇摆和绝缘子串位移响应,结果反映了输电线路绝缘子—导线耦合模型脉在动风下的特性规律。

In this paper, the effect of lfuctuating wind on the wind bias of insulator conductor coupled model of transmission line is studied. First select the actual line is the more common form of ifve span transmission line were used to simulate the lfuctuating wind ifeld, simulation of different spans the distance between the wire origin 50m of lfuctuating wind speed process and the corresponding target spectrum and simulated spectrum curve coincide, then a transmission line - insulator coupling model, calculated under the action of lfuctuating wind wire at the same time swing and insulator string displacement response. The results indicates that the transmission line insulator - wire coupling model of pulse in the dynamic characteristics of the wind.
