Abstract: As the name implies, the optimization of cutout speed is to maximize the wind speed of gentrator sets and enhance utlization ratio of wind energy & draught fan. Through the combination of optimized software and hardware, we have reduced power and adjusted add resistance algorithm between the former and the new cut-out speed to inarease power output without destorying generator sets. After ewploying the optiwized generator sets, it yielded considerable benefits. For example, the power output in 50 MW wind power plant will increase by 6.65% in theory while the actual increment in power output is 11.546 million k Wh.Besides, it enhanced 233.3 standard hours.

Key words: optimization of cut-out speed, utilization ratio, power output
