摘要(Abstract):
针对风电机组变桨系统非线性、时滞、多干扰的特点,提出了一种风电机组变桨复合控制策略,即前馈控制与差分进化-模糊PID(比例积分微分)结合的控制策略。策略中,为了动态补偿桨距角,提高系统响应速度,将风速作为前馈信号引入控制系统;采用模糊PID控制器提高系统抑制扰动能力及鲁棒性;采用差分进化算法优化PID初始参数,并通过模糊规则对PID控制器参数进行动态修正。将所提基于差分进化-模糊PID的前馈控制应用于2 MW的变桨距直驱风电机组中,与差分进化-模糊PID控制和模糊PID控制仿真对比,结果显示所提策略可使风电机组输出功率更加稳定,验证了所提控制策略的有效性。
In view of the characteristics of non-linearity,time delay and multiple disturbances of wind turbine pitch system,this paper proposes a wind turbine pitch compound control strategy. In the strategy,wind speed is introduced into the control system as a feedforward signal to dynamically compensate the pitch angle and improve the system response speed. In order to improve the robustness and the system′s ability to suppress disturbances,a fuzzy PID(proportion-integral-derivative)controller is used. The differential evolution algorithm is adopted to optimize the initial parameters of PID,and the PID controller parameters are dynamically modified through fuzzy rules. The proposed strategy is applied to a 2 MW direct-drive wind turbine and compared with differential evolution-fuzzy PID control and fuzzy PID control. The results show that the proposed strategy can make the output power of the wind turbine more stable,which verifies the effectiveness of the proposed control strategy.
