摘要
本文研究的是风电机组功率曲线的优化方法。首先分析功率曲线的影响因素,分别从空气密度(包括气压、环境温度和湿度)、扫风面积、风速、风能利用系数及机组效率这几个方面展开分析,研究各个影响因素对功率曲线的影响作用。然后,针对风电机组功率曲线的影响因素,探索优化风机功率曲线的方法,包括:桨叶角度检查、风向标的检查、风速仪的检查、环境温度的检查、海拔高度参数的检查及功率控制参数Kopt值的检查,并用实际风电机组整改案例去验证功率曲线优化方法的正确性。
The thesis studies the optimization method of wind turbine power curve.Firstly,the influence factors of power curve is analyzed,respectively from the air density(including air pressure,ambient temperature and humidity),swept area,wind speed,wind turbine power cofficient,unit efficiency are analyzed to study the influence of various factors on power curve.Then,explor the optimization method of wind turbine power curve through the influence factors of wind turbine power curve which include check blade angle,inspection of weathervane,inspection of anemometer,check ambient temperature,check elevation parameters,check the power control parameter Kopt,the correctness of the power curve optimization method is verified by the actual wind turbine rectification case.
