一種抑制風(fēng)力發(fā)電系統(tǒng)輸出功率波動(dòng)的直流側(cè)電壓控制方法:本文提出一種風(fēng)力發(fā)電系統(tǒng)中抑制功率波動(dòng)的控制策略。這種控制策略充分利用直流側(cè)的儲(chǔ)能
元件，允許直流側(cè)電壓在一定范圍內(nèi)波動(dòng)，從而抑制風(fēng)力發(fā)電系統(tǒng)輸出功率的波動(dòng)，同時(shí)它也不影響風(fēng)力發(fā)電系統(tǒng)的最大風(fēng)能跟蹤。仿真和實(shí)驗(yàn)都驗(yàn)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.
