根据风速的大小,将变速恒频风力发电机组整个并网运行阶段划分为4个区域,每个区域采用不同的控制算法.在额定风速以上,为应对极端风况,引入2个变桨控制器,分别对发电机转速和加速度进行控制.利用风力发电领域权威仿真软件--GH Bladed对控制算法进行了仿真验证.将控制策略应用在某风力发电场的双馈风力发电机组上,获得了较为理想的效果.
根據風速的大小,將變速恆頻風力髮電機組整箇併網運行階段劃分為4箇區域,每箇區域採用不同的控製算法.在額定風速以上,為應對極耑風況,引入2箇變槳控製器,分彆對髮電機轉速和加速度進行控製.利用風力髮電領域權威倣真軟件--GH Bladed對控製算法進行瞭倣真驗證.將控製策略應用在某風力髮電場的雙饋風力髮電機組上,穫得瞭較為理想的效果.

The operation section is divided into four regions according to the different control strategies,dif-ferent regions with different control algorithm. Above the rated wind speed, two pitch controllers which control generator speed and accelerate speed respectively are introduced to respond extreme wind speed. Simulations are conducted in the professional software Bladed based on the proposed control strategies. Finally, the field experiments are carried out in wind plant of doubly-fed wind turbine. The stability and validity of control strat-egies are proved completely.
