    • A method and associated control arrangement are disclosed for controlling a de-rated power output of a wind turbine generator, where the wind turbine generator is associated with a predetermined power ramp rate upper limit and operating with a de-rated rotor speed. The method includes ramping the power output from an initial power level to a target power level during a ramping interval. During a first portion of the ramping interval, the power output is ramped at a first power ramp rate less than the power ramp rate upper limit. The method further includes ramping the rotor speed to a predetermined rotor speed value contemporaneously with ramping the power output during the first portion of the ramping interval. The first power ramp rate is determined such that a difference between the power output and the target power level is monotonically decreasing during the entirety of the ramping interval.

    • The invention relates to a method of controlling a wind turbine, the wind turbine comprising wind turbine blades attached to a rotor hub and a control system for pitching the blades relative to the hub. The method comprises providing wake sectors assigned to different wind directions and providing a normal pitch schedule to control an output parameter of the wind turbine (e.g. power, rotational speed), comprising pitch reference values as a function of the wind speed and at least one of the parameters of thrust coefficient C t and axial induction factor a. Further, is provided a modified pitch schedule to control a modified output parameter of the wind turbine, comprising pitch reference values in dependence of the wind speed and at least one modified parameter of the thrust coefficient and/or the axial induction factor. Upon receiving indications of a wind speed and a wind direction at the wind turbine is determined a pitch reference value for the wind turbine blades according to the normal pitch schedule if the wind direction falls outside the wake sector and otherwise according to the modified pitch schedule. The wind turbine is then controlled according to the pitch reference value. The invention further relates to a method of controlling the wind turbines in a wind park, wherein each wind turbine in the park is controlled locally according to the above mentioned control method.

    • This invention relates to a method and a power plant controller arranged to carry out the method. The method is on an intelligent dispatching of the power production to wind turbines and optional compensation equipment of a wind power plant, as the power producing units of a wind power plant. The invention relates to a case where the requested produced power is less than the total capacity of the power plant, and the invention relates to utilizing this situation to dispatch set points to the wind turbines and the compensation equipment in a flexible way. This flexibility may increase the wind turbines' life time, help in scheduling maintenance and expand the electrical operating range of the wind power plant. The determination of the set points on active and reactive power is a combined determination of both set points for each of the energy producing units of the wind power plant.

    • Embodiments herein describe varying the rotor speed based on the current wind speed when operating in a low power mode. Generally, as the wind speed increases above the rated wind speed (i.e., the wind speed at which the turbine is capable of producing its rated or maximum output power), the rotor speed can be reduced thereby minimizing the risk that the turbine experiences smearing or torque reversals. In one embodiment, as the rotor speed decreases, the turbine maintains the ability to ramp to the rated power of the turbine only by pitching in the blades to an optimal blade pitch angle. Thus, upon receiving a request to cease operating in the low power mode, the turbine can increase the output power to the rated power without first increasing the rotor speed.
    • 本文的实施例描述了当在低功率模式下操作时基于当前风速来改变转子速度。 通常,随着风速增加到额定风速以上(即,涡轮机能够产生其额定输出功率或最大输出功率的风速),可以降低转子速度,从而最小化涡轮机出现拖尾的风险或 扭矩反转。 在一个实施例中,随着转子速度降低,涡轮机仅通过在叶片中俯仰至最佳叶片桨距角而维持升高至涡轮机的额定功率的能力。 因此,在接收到停止在低功率模式下运行的请求时,涡轮机可以在不首先增加转子速度的情况下将输出功率增加到额定功率。
