介绍了风电特性和特高压直流故障对电网的影响，分析了特高压直流故障对风电送出可靠性的影响。通过对系统进行模拟仿真，发现通过优化直流无功控制系统与稳控系统间的动作配合等措施，对减小直流系统故障对系统电压波动及风机脱网的影响有明显的作用。

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 mea-sures, there are obvious effects on reducing the impact of DC fault on the system voltage fluctuation and the takeoff grid of wind-driven generator.
