摘要 提出一种建立水平轴风电机组短时风速模型的方法,首先根据自然风短时风速的湍流特性,建立自然风短时风速模型;然后研究风轮旋转效应和塔影效应对自然风短时风速的影响,建立包括风轮旋转效应和塔影效应的水平轴风电机组的短时风速模型。对建立的短时风速模型进行仿真分析,证明该方法建立的水平轴短时风速模型能客观地反映自然风短时风速流经风电机组的短时风速动态过程。 The short-term wind speed model of wind turbine generation system is the primary requirement for studying dynamic characteristics of wind turbine generation system and its optimal operation. A new method for establishing the short-term wind speed model of horizontal axis wind turbine was proposed. Fir, short-term wind model of natural wind was created according to the turbulence characteristics of short-term wind speed of natural wind; secondly, the influence of wind rotor rotating effect and tower shadow effect on short-term wind speed of natural wind was discussed, and then based on the above effects analysis, the short-term wind speed model of horizontal axis wind turbine was established. By simulating and analyzing the short-term wind speed model of horizontal axis wind turbine, the results show that the short-term wind speed model of horizontal axis wind turbine can describe the dynamic characteristics of short-term wind speed of natural wind to pass wind turbine generation system objectively.
