    高风速高湍流强度下风电偏航系统降载对风控制

    Load Reduction Control of Wind Turbine Yaw System Under High Wind Speed and Turbulence Intensity Condition

    • 摘要: 针对风电机组在高风速、高湍流强度工况下偏航轴承易受冲击载荷、严重消耗寿命的问题,提出一种基于麻雀算法-自抗扰的偏航系统降载执行对风控制策略。利用麻雀算法对自抗扰控制器的参数进行全局寻优,并通过FAST-Simulink联合仿真平台进行对比验证。结果表明:在高风速高湍流工况下,相较于传统PI和遗传模糊控制策略,该策略降载效果显著,其X–Y平面方向的疲劳载荷和极限载荷均可降低约70%。该方法能有效抑制随机气动载荷对系统的冲击,对延长偏航系统使用寿命具有重要应用价值。

       

      Abstract: Aiming at the problem that wind turbine yaw bearings are susceptible to impact loads under high wind speed and high turbulence intensity conditions, which severely consumes their service life, a load-reduction yaw control strategy based on sparrow search algorithm (SSA) and active disturbance rejection control (ADRC) is proposed. The SSA is utilized to perform global optimization on the parameters of the active disturbance rejection controller, and comparative verification is conducted via the FAST-Simulink co-simulation platform. Results show that compared with the traditional PI and genetic fuzzy yaw control strategies , the proposed strategy has a significant load reduction effect under high wind speed and high turbulence conditions, with both the fatigue load and ultimate load in the X–Y plane reduced by approximately 70%. This method can effectively suppress the impact of random aerodynamic loads on the system, which has important application value for extending the service life of the yaw system.
