    Abstract: Aiming at the frequent occurrence of wind damage tripping in micro terrain region of certain northwest province in recent years, according to the collection of meteorological conditions and environmental messages when the faults such as windage yaw, surge tank and foreign short circuit etc happened, this paper carried out statistic analysis of wind damage faults happening from 2010 to 2017 in the region and studied on the relative merits of various types of wind damage prevention measures. According to the characteristics of different types of wind damages, this paper proposed the countermeasures for wind damage and suggestions, which provides references for the transmission line wind damage prevention work.
    Key words: transmission line; micro terrain; wind damage fault; prevention measures
