【摘要】：随着风电渗透率的增加,间歇风速对系统运行的影响不可忽视。建立间歇性风速模型和间歇风速下的风机功率输出模型,对解决电力系统规划运行问题至关重要。间歇性风速模型可以确定历史风速数据中强波动性风速。间歇风速下的风机功率输出模型可以评估风速间歇变化过程的风电场输出功率。首先,根据混沌理论建立间歇性风速模型,确定间歇性风速区间以及区间内的间歇性风速。其次,利用动量-叶素理论建立风力发电机功率输出模型,根据风速变化时桨叶的受力情况,评估间歇风速下的风力发电机输出功率。最后,利用大同某风电场采集的数据验证所提方法的有效性。
[Abstract]:With the increase of wind power permeability, the influence of intermittent wind speed on system operation can not be ignored. The intermittent wind speed model and the fan power output model under intermittent wind speed are established. The intermittent wind speed model can determine the strong fluctuating wind speed in the historical wind speed data. The wind turbine power output model under intermittent wind speed can be used to evaluate the intermittent variation process of wind speed. Wind farm output power. First, According to the chaos theory, the intermittent wind speed model is established, and the interval of intermittent wind speed and the interval intermittent wind speed are determined. Secondly, the power output model of wind turbine is established by using the momentum-leaf element theory. The output power of wind turbine under intermittent wind speed is evaluated according to the force on the blade when the wind speed changes. Finally, the validity of the proposed method is verified by using the data collected from a wind farm in Datong.
