自阻尼条件下架空输电导线风振功率研究

Study on Aeolian Vibration Power of Transmission Line under Self-damping Condition

为了掌握线路的振动状态,保证线路安全,需要确定大跨越架空导线的风振功率曲线。应用Slethei风能曲线、Diana风能曲线和导线AACSR-400自阻尼特性的试验结果,得到了该导线的风振平衡点和风振功率点的数据。对导线AACSR-400风振功率点的计算结果表明,在确定风振平衡点时,Diana风能曲线优于Slethei风能曲线。

In order to understand the vibration state of overhead transmission line and ensure the operational security, it is necessary to determine the wind vibrating power curve for a large-span overhead conductor. In this paper, the data of wind vibrating balance point and wind vibration power point are obtained by using the Slethei wind energy curve, Diana wind energy curve, and the experimental results of the self-damping characteristics of conductor AACSR-400. The calculation result of the wind-vibration power point of conductor AACSR- 400 shows that the Diana curve is better than the Slethei curve for determining the wind vibrating balance point of the conductor.
