提出了一种基于滑模控制理论的非线性控制方法，用于抑制基于并网型双馈感应发电机（DFIG）的风力发电机组的扭振。所提出的方法通过减少由机械或电气干扰引起的扭转振动来增加风力涡轮机的寿命。所提出的技术的有效性证明了由电压骤降和阵风引起的扭转振动。在本文中，动力学的发电机，多惯性传动系统，转子和电网侧转换器，和传输线的750千瓦的疲劳，空气动力学，结构和湍流（FAST）模拟器风力涡轮机模型，包括风力涡轮机空气动力学。
This paper presents a nonlinear technique based on the sliding mode control theory for mitigation of torsional vibrations in grid-connected doubly fed induction generator (DFIG) based wind turbines. The presented method increases the lifespan of wind turbines by reducing torsional vibrations caused by mechanical or electrical disturbances. The effectiveness of the proposed technique is demonstrated on torsional vibrations caused by a voltage dip and a wind gust. In this paper, dynamics of the generator, multiinertia drivetrain, rotor- and grid-side converters, and transmission line are developed upon the 750-kW fatigue, aerodynamics, structures, and turbulence (FAST) simulator wind turbine model comprising wind turbine aerodynamics.
