【 摘 要 】

The distribution characteristics of wind speed and the features of wind load of transmission lines in Gansu Province are studied on the basis of the statistical data observed by meteorological stations and the results of CFD simulation. Research shows that most areas of Gansu are in the gale region where the average wind speed is higher than 17.2m/s, and the transmission lines are highly stressed; the wind load coefficients of smooth round conductors are 1.12 and 1.18 respectively when the average wind speed is 20m/s and 30m/s; under gale weather conditions, type conductors and smooth conductors mostly happen to large wind deflection, while round stranded conductors are in the state with random vibration and wind deflection coexisting.
