Abstract: Disclosed is a method, performed by an electronic device, for validation of a second version of a software or a second structure model for control of a wind turbine. The method comprises obtaining first load data from simulating a load of the wind turbine using a first structural model and a first version of the software. The method comprises obtaining second load data from simulating the load of the wind turbine using the first structural model and the second version of the software or using the first version of the software and a second structural model. The second version of the software is an update of the first version of the software. The second structural model is an update of the first structural model. The method comprises determining, based on the first load data and the second load data, a statistical parameter.

Abstract: The disclosure relates to controlling blade pitch in a wind turbine that has a plurality of rotor blades and a hydraulic pitch system for adjusting a pitch of each of the rotor blades. The disclosure describes a method comprising obtaining a measurement indicative of a current level of hydraulic pressure available in the hydraulic pitch system, and determining, based on the obtained measurement, an adaptive pitch reference rate indicative of a rate at which the pitch of the rotor blades is to be adjusted by the hydraulic system. The method includes controlling the hydraulic pitch system to adjust the pitch of the rotor blades in accordance with the determined adaptive pitch reference rate.

Abstract: A wind turbine control unit comprising a control module configured to control an actuator system by outputting a first control signal, wherein the first control signal includes a current control sample value and a predicted control trajectory; the control unit further comprising an upsampling module configured to receive the first control signal from the control module, and to output a second control signal for controlling the actuator system, the second control signal having a higher frequency that the first control signal. The upsampling module calculates the second control signal in dependence on the current control sample value and the predicted control trajectory. The embodiments provide a more accurately reproduced control signal at a higher frequency that is suitable for onward processing which does not suffer from the problems of aliasing and delay that exist with conventional upsampling techniques.

Abstract: Aspects of the present invention relate to a method of controlling a renewable power plant comprising a plurality of renewable power generators electrically connected by a local network and configured to supply active power to a main network. The method comprises: in response to receiving a signal requesting substantially zero active power supply to the main network: categorizing a generator as power-supplying, and the remaining generators as power-consuming; operating the power-consuming generators to generate no active power and to have their auxiliary systems draw power from the local network; and operating the power-supplying generator to supply active power to the local network such that the plant supplies substantially zero active power to the main network.

Abstract: A method of operating a wind turbine having a rotor. Sensor data is received from one or more sensors of the wind turbine and maximum load values are obtained on the basis of the sensor data. The maximum load values are indicative of maximum loads acting on a component of the wind turbine such as a rotor blade. An estimated extreme load value, such as a 50-year return load, is obtained on the basis of the maximum load values and compared with a reference value. A maximum thrust limit is set on the basis of the comparison, and the wind turbine is operated in accordance with the maximum thrust limit so that a wind thrust force acting on the rotor does not exceed the maximum thrust limit.

Abstract: A method of controlling a wind turbine is described. The method comprises calculating a current wear rate for each of the main bearing of a turbine rotor and the blade bearings of rotor blades mounted on the turbine rotor, and calculating a blade pitch adjustment of the rotor blades to achieved a desired ratio between main bearing wear and blade bearing wear in dependence on the calculated current wear rates of the main bearing and the blade bearings.
