Abstract

Abstract: 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.

Key words: overhead transmission line, dancing, aero-vibration, self-damping characteristics, wind vibration power
