中文摘要：
为提高大型风力发电机组捕获风能的能力,改善其主要零部件受荷载情况,提出基于有效风速估计和风剪切的风力发电机组独立变桨距控制策略。以某5 MW变速变桨风力发电机组为验证对象,基于Bladed软件平台对传统统一变桨控制策略和独立变桨控制策略进行仿真比较。结果表明：相对于统一变桨距控制策略,独立变桨距控制策略不但能满足维持风力发电机组输出功率额定值稳定的要求,而且使发电机组主要零部件的受荷载情况得到明显改善。
英文摘要：
To enhance the capability of large-scale wind turbines to capture wind energy and improve their primary components load, an individual pitch control strategy based on the estimated wind speed and wind shear is proposed. A case study was conducted on 5 MW variable-speed variable-pitch （VSVP） wind turbines. The Bladed software was used to simulate and compare this individual pitch control strategy and the traditional collective pitch control strategy. Simulation results show that, compared with the traditional collective pitch control strategy, the proposed individual pitch control strategy can not only match rotational power, but also improve the load conditions of primary components of wind turbines.
