摘要:
      针对常规风电场有功功率分配中,通过风速评价机组的功率调节能力不准确的问题,提出一种基于数据驱动的风电场有功功率分配算法。首先,采集不同风速下风电机组转速和桨距角数据,利用Takagi-Sugeno模糊模型和变异系数法评价变速系统和变桨系统参与功率调节的相对权重系数,确定机组的功率调节能力。然后,完成基于机组调节能力的风电场有功功率分配。最后,在MATLAB仿真平台上完成含有10台风电机组的风电场有功功率分配。仿真结果表明,与按风速权重有功功率分配算法相比,所提分配算法的风电场有功功率波动小,风电机组的转速和桨距角变化较为平滑,且高风速机组的载荷小。
Abstract:
      Aiming at the inaccuracy problem of power regulation capacity of units evaluated by wind speed for active power distribution in conventional wind farms, a data-driven based active power distribution algorithm in wind farm is proposed. Firstly, the data of rotation speed and pitch angle is obtained at different wind speeds. The relative weight coefficient of variable speed system and pitch system is evaluated by the coefficient of variance method and Takagi-Sugeno fuzzy model, which can determine the adjustment capability. Then, the active power distribution of wind farm is established based on the adjustment capability of turbines. Finally, the active power distribution algorithm in wind farm with 10 wind turbines is completed in MATLAB. The simulation results show that, comparing with the distribution algorithm of wind speed weight, the fluctuation of active power in wind farm is smaller using the proposed method, the amplitude of variable speed system and pitch system is smoother, and the load of high-speed wind turbine is lower.
