摘　　要：基于对风电场输出功率与输入风速关系的分析,提出了考虑风速的风电场等值方法。该方法考虑了风电机组在不同风速情况下风能利用系数不同的特点,将风能利用系数描述为风速的分段函数并将其作为权值对风速加权等值。对所提等值方法与传统的不考虑风能利用系数差异的等值方法进行了仿真比较,结果表明所提等值方法较传统等值方法等值误差更小。Based on the analysis of the relationship between the output power of wind farm and the input wind speed,a method of wind farm equivalence considering wind speed is proposed,which,considering the wind power utilization coefficient of wind generator varies along with the wind speed,describes piecewise the wind power utilization coefficient as the function of wind speed and takes it as the weight of equivalent wind speed.The proposed equivalence method is compared with the traditional equivalence method by simulation and result shows that the error of equivalence considering different wind power utilization coefficients is smaller.
