    Abstract: A method and associated control arrangement are disclosed for controlling a power output of a wind power plant (WPP) according to a predetermined power ramp rate limit, the WPP comprising a plurality ofwind turbine generators (WTGs). The method comprises receivinga first signal indicating that afirst WTG is in a ready state to begin producing power. The method further comprises, upon determining that, responsive to the received first signal, beginning power production of the first WTG at a predetermined default power ramp rate would cause the power output of the WPP to exceed the power ramp rate limit, controllingpower production of the first WTG using at least one of: a first delay, a power ramp rate reference less than the default power ramp rate, and a power reference less than a nominal power output of the first WTG.

    Abstract: The invention relates to a control system for a wind turbine. The wind turbine comprises a power generator configured to generate power dependent on a power reference and a pitch system configured to adjust the pitch of a blade of the wind turbine dependent on a pitch request. The control system comprises a controller configured to determine the pitch request dependent on an adjustable gain. A gain scheduler comprised by the control system is configured to set the adjustable gain to an increased gain value if a rate of change of the power reference, e.g. an external power reference, exceeds a threshold.

    Abstract: 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.

    Abstract translation: 本文的实施例描述了当以低功率模式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(即,涡轮机能够产生其额定或最大输出功率的风速),可以减小转子速度,从而最小化涡轮机遭受拖尾或风险的风险 转矩反转。 在一个实施例中,随着转子速度的降低,涡轮机仅通过在叶片中俯仰至最佳叶片俯仰角而保持斜坡至涡轮机的额定功率的能力。 因此,在接收到在低功率模式下停止运行的请求时,涡轮机可以在不首先提高转子速度的情况下将输出功率提高到额定功率。

    Abstract: The invention relates to a method for controlling a wind turbine in partial and full load. In order to avoid disadvantages of switching between partial and full load controllers, the wind turbine control system is configured so that both the partial and full load controller provides control action during partial and full load. For that purpose, the partial and full load controllers are configured with variable gains, wherein gain scheduling is performed so that the gain of partial load controller is larger than the gain of the full load controller during partial load and vice verso so that the gain of the full load controller is larger than the gain of the partial load controller during full load.

    Abstract: The invention relates to turbulence sensor for wind turbine blades. The sensor is configured to promote turbulence of air flowing over the blade at a location of the sensor which comprises a detector configured to detect air turbulence. Since the sensor promotes turbulence compared to adjacent locations of a wind turbine blade the sensors can be used to predict that the blade is close to a stall conditions.
