    • The application describes a wind turbine having a control method and controller for performing predictive control of a wind turbine generator. Based on the measured instantaneous wind speed, it is known to provide control signals to a wind turbine in order to control the pitch of the wind turbine rotor blades and the speed of the generator. However, it is difficult using instantaneous wind speed measurements to achieve smooth control, due to finite response speeds of the associated electro-mechanical systems, as well as the constantly changing control system inputs. The predictive control system described in the application assumes a model of generator speed based on the values of the incident wind speed v(t) and the values of a control signal u(t) output to the wind turbine in a feed forward loop. Here, the control signal can be for one or more of controlling either the power setting of the generator, or the pitch angle of the rotor blades. The predictive controller uses a rolling time series of values for v(t) and u(t) and based on a predicted response of the generator speed w(t) optimises the time series control signal u(t). The predicted response of the generator speed w(t) is based on model, that can be refined in real time as the wind turbine operates.
    • 该申请描述了具有用于执行风力涡轮发电机的预测控制的控制方法和控制器的风力涡轮机。 基于所测量的瞬时风速,已知将控制信号提供给风力涡轮机以便控制风力涡轮机转子叶片的倾斜度和发电机的速度。 然而,由于相关机电系统的有限响应速度以及不断变化的控制系统输入,因此使用瞬时风速测量来实现平滑控制是困难的。 本申请中描述的预测控制系统基于在前馈回路中输入到风力涡轮机的入射风速v(t)和控制信号u(t)的值来假设发电机速度的模型。 这里,控制信号可以用于控制发电机的功率设置或者转子叶片的桨距角中的一个或多个。 预测控制器使用v(t)和u(t)的滚动时间序列值并且基于发电机速度w(t)的预测响应来优化时间序列控制信号u(t)。 发电机转速w(t)的预测响应基于模型,可以随着风力涡轮机的运行而实时改进。
