RESEARCH ON CONDUCTOR GALLOPING OF LARGE SPAN LINE IN ULTRA-HIGH VOLTAGE TRANSMISSION LINE

摘要

Carry out conductor anti-galloping research on Xiangjiang large span in Xiluodu - Zhexi ±800kV ultra-high voltage DC transmission engineering. This paper analyzes metrological and terrain conditions of the area passing by Xiangjiang large span engineering, which clarifies galloping occurrence condition of the conductor in the large span engineering; give out main galloping characteristics of Xiangjiang large span engineering under given meteorological conditions by means of value simulation method.
