一種抑制風力發(fā)電系統(tǒng)輸出功率波動的直流側電壓控制方法:本文提出一種風力發(fā)電系統(tǒng)中抑制功率波動的控制策略。這種控制策略充分利用直流側的儲能
元件，允許直流側電壓在一定范圍內波動，從而抑制風力發(fā)電系統(tǒng)輸出功率的波動，同時它也不影響風力發(fā)電系統(tǒng)的最大風能跟蹤。仿真和實驗都驗證了這種控制策略的正確性。
Abstract: A novel control strategy for damping power fluctuation in wind power system is proposed in this paper. This strategy is realized by an appropriate DC link voltage regulation, which takes sufficient use of DC link capacitor and tolerates DC link voltage changes within a certain range. Within the permitted voltage range of DC side, using the novel DC link voltage control to damp output power fluctuation has the advantage of no degradation of the maximum wind power tracking capability of the generator control system. Simulation results based on Saber and experimental results demonstrate the validity of the proposed control strategy.
