Abstract: Introduction was made to the wind power characteristics and the impacts of ultra high voltage (UHV) direct current (DC) fault on the grid and analysis was made to the impact of UHV DC fault on the output reliability of wind farm. The system simulation shows that via optimizing action and collocation between the DC reactive control system and the stability control system etc measures, there are obvious effects on reducing the impact of DC fault on the system voltage fluctuation and the takeoff grid of winddriven generator.
         Key words: ultra high voltage direct current; wind farm; voltage; takeoff grid; reliability
