变桨矩风力发电机组输出功率控制方法的应用研究

Application Study on Control Method of Output Power of Pitch Wind Power Generation Unit

由于功率与风能的三次方成正比,风速的较小变化将造成风能的较大变化,且由于风的随机性和不稳定性等特点,使风机的输出功率处于不断变化之中,因此给大型风力发电机组输出功率的控制带来困难。以变桨距调节方式为依托,通过对变距调节时的阻力矩进行分析,对先进的RCC控制技术进行研究,并以风场实际应用结果做相应比对,得出了一套较为系统的输出功率控制方法。

As the power and wind energy is proportional to the cube of wind speed,so smaller changes of the wind speed will result in major changes of wind energy.Because wind is always random and not stable,the output power of the fan is constantly changing,so the output power control of the large power generations is very difficult.Based on the pitch regulation and analysis of resistance moment,the RCC control technology is studied in this paper,comparing the application result with the calculated result,and a more systematic method of output power control is obtained.
