Abstract: To efficiently run a wind turbine in varying wind speeds, the wind turbine may be configured to switch between two different electrical configurations that offer different efficiencies depending on wind speed. For example, a star configuration may be preferred during low wind speeds while a delta configuration is preferred for high wind speeds. Before switching, the power output by the turbine's generator may be driven to zero. Doing so, however, removes load from the rotor blades which cause the rotor speed to increase. Instead, the rotor speed may be controlled such that the speed stays at or above the speed of the rotor immediately before the generator power is ramped down. Maintaining rotor speed at or slightly above the current speed while switching between electrical configurations may mitigate the torque change experienced by the turbine and reduce the likelihood of structural failure.

Abstract translation: 为了在不同的风速下有效地运行风力涡轮机，风力涡轮机可以被配置为在根据风速提供不同效率的两种不同的电气配置之间切换。 例如，在低风速期间，星型配置可能是优选的，而对于高风速，优选配置三角形配置。 在切换之前，涡轮发电机输出的功率可能被驱动到零。 然而，这样做可以消除转子叶片的负载，导致转子速度增加。 相反，可以控制转子速度，使得在发电机功率下降之前，转速保持等于或高于转子的速度。 在转换电气配置之前，将转子速度保持在或略高于当前速度可以减轻涡轮机所经历的扭矩变化，并降低结构故障的可能性。

Abstract: The invention relates to a method for controlling a wind turbine to change a power reference Pref from a first power level to a second power level dependent on a comparison of a grid frequency f with a frequency threshold fT. In order to enable fast changes of the power reference Pref in case of a relatively large deviation of the grid frequency relative to the nominal grid frequency, a power ramp rate allowing a fast change of the power reference may be set if the grid frequency is greater than the frequency threshold.

Abstract: The present invention relates to control of the power output of wind turbine generator that operates in derated mode to generate a produced power output level lower than an available power level. A pitch system 48 sets the blade pitch of a rotor to a pitch value based on the received power reference signal 40. A power system 43 controls the produced power output power level of the wind turbine to the requested power output level. Moreover, the blade pitch of the rotor is further controlled by a pitch feedback control loop 47 that modifies the pitch value based on a difference between the produced power output level 46 and the requested power output level 40.
