摘要
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。
The operation section is divided into four regions according to the different control strategies, different 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.
