Abstract: The invention provides a method of shutting down a wind turbine, the wind turbine comprising a rotor with a plurality of blades; and a generator system coupled to the rotor. The method comprises: operating the generator system to generate electrical power and apply a load torque to the rotor; controlling the electrical power generated with a power reference signal; determining that a shutdown of the wind turbine is required; in response to the determination that a shutdown of the wind turbine is required, changing the power reference signal so as to increase the electrical power generated thereby slowing the rotor; determining that a speed of the rotor has reduced below a threshold; and in response to the determination that the speed of the rotor has decreased below the threshold, changing a pitch of the blades to further slow the rotor.

a sum of the positive half-period area of the filtered signal and the negative half-period area of the filtered signal is below a first threshold; and
the absolute value of one of the positive half-period area and negative half-period area is above a second threshold.

Abstract: Controlling a renewable energy power plant, such as a wind power plant, when a frequency level of a power network, to which the power plant is connected, is outside of a frequency deadband. Aspects of the invention may be used to control the active power output of a wind energy power plant and to dampen oscillations in the controlled power characteristic when the frequency level of the connected power network is fluctuating outside of the frequency deadband.

Abstract: A method for controlling wind turbines of a wind farm is disclosed. The wind farm is positioned at a site which includes one or more turbulence generating structures, such as hills, valleys, trees or buildings. A wind direction at the site of the wind farm is detected, and one or more upstream wind turbines and one or more downstream wind turbines are identified, based on the detected wind direction, where each of the upstream wind turbines is arranged in front of one or more of the downstream wind turbines, as seen in the wind direction. If it is detected that turbulent wind conditions are occurring, based on measurements performed by the wind turbines of the wind farm, then at least one of the upstream wind turbines is controlled based on measurements performed by at least one wind turbine which is a downstream wind turbine relative to the upstream wind turbine.

Abstract: A method for operating a cluster of a plurality of wind turbines is disclosed. For each of the wind turbines, one or more parameter values of a parameter being indicative for a condition occurring at the wind turbine are derived, based the measurements obtained by the wind turbine. In the case that a derived parameter value for a specific wind turbine exceeds a trigger value, measures for mitigating an effect of the condition at the specific wind turbine are initiated. The derived parameter values for the wind turbines of the cluster of wind turbines are compared to an expected distribution of the parameter values. In the case that a distribution of the derived parameter values differs from the expected distribution of the parameter values, the trigger value is adjusted, and the adjusted trigger value is subsequently applied when comparing the derived parameter values to the trigger value.

Abstract: A wind turbine (10) includes a nacelle (14) with a longitudinal axis (LA) aligned with the flow of the incoming wind during operation. When so aligned, the nacelle defines a longitudinal direction (X). The wind turbine (10) includes one or more heat-generating components (22) and a modular cooler (24) operatively coupled to the one or more heat-generating components (22). The modular cooler (24) includes one or more cooling modules (30) with each including one or more cooling units (32). Each cooling unit (32) includes a heat exchanger (40) defining a cooling area (38), which defines a normal axis (NA) and a deflector plate (42) to divert the flow of the incoming wind by an angle less than 180° relative to the longitudinal direction (X). Each cooling unit (32) is oriented such that the normal axis (NA) is non-parallel to the longitudinal axis (LA). The modular cooler (24) is scalable in multiple dimensions to increase the cooling capacity of the cooler (24). A method of assembling the modular cooler (24) is also disclosed.

Abstract: A method of installing a wind turbine (10) at an offshore location. The wind turbine (10) includes a tower (18) and an energy generating unit (16). The tower (18) is configured to be secured to a transition piece (12, 42). Prior to shipping, the method includes electrically coupling electrical devices and/or systems (52) by cables (54) to energy generating unit (16) or wind turbine tower (18) or a test dummy therefor. The electrical devices and/or systems (52) are configured to be attached to transition piece (12, 42) once the tower (18) is installed. The method includes testing and commissioning the electrical devices and/or systems (52) while electrically coupled to the cables (54). Prior to shipping and after testing and commissioning, the method includes storing the electrical devices and/or systems (52) and attached cables (54) inside the tower (18). The cables (54) are long enough to permit the electrical devices and/or systems (52) to be attached to the transition piece (12, 42) without disconnecting the electrical devices and/or systems (52) from the cables (54).
