    Abstract: A method of providing safety configuration parameters for a wind turbine is provided. The method comprises receiving a safety configuration file at a location of the wind turbine, and comparing a turbine ID associated with the safety configuration file to a turbine ID of the wind turbine stored at the location of the wind turbine. A tamper check is performed on the safety configuration file to determine if data in the safety configuration file has been modified. If the turbine ID associated with the safety configuration file matches the turbine ID of the wind turbine, and if the tamper check determines that the data has not been modified, a safety configuration parameter associated with a safety system of the wind turbine is extracted from the file and stored.

    Abstract: The present invention relates to a rotor control system for actuating pitch of pitch adjustable rotor blades in order to reduce vibrations of a wind turbine element, e.g. tower vibrations. A pitch modification signal is determined which is based on an m-blade coordinate transformation, such as the Coleman transformation. The m-blade coordinate transformation taking as input a first signal and a second signal. The second signal is determined by filtering the first signal with a signal filter with a quadrature phase shift filter phase response.

    Abstract: The present disclosure relates to a control system for a wind turbine comprising more controllers and where at least some of the controllers operate at different sample frequencies. The control system comprises at least two controller units, a first controller (10) for determining an operational value (OV) of a sub-system and a second controller (20) for the sub-system. The second controller operates at a higher sample frequency than the first controller. It is disclosed that a faster reaction to a received demand value (V1), received for controlling the sub-system, can be obtained by setting the operational value (OV) of the sub- system as the sum of an internal operational value (V5) and a difference value (V4).

    Abstract: The present invention relates to control of wind turbines in a situation where a fault condition is detected. Control of a wind turbine is described where a control trajectory and a safe-mode trajectory are calculated based on the current operational state of the wind turbine. If the fault condition is detected the wind turbine is controlled using the safe-mode trajectory, otherwise, the normal operation of the wind turbine is continued where the wind turbine is controlled using the control trajectory.

    Abstract: A method for controlling a wind turbine during a safety operation is disclosed. A safety pitch control system is provided to pitch the blades individually at a number of pre-set approximately constant pitch rates including a first pitch rate and a second pitch rate lower than the first pitch rate. In response to a command for initiating the safety operation the blades are pitched towards a feathering position by the safety pitch control system including the blades being pitched according to a safety pitch strategy wherein for all the blades the pitch rate is changed between the first pitch rate and the second pitch rate according to a function of each blade azimuthal position. This is done such that each blade in turn is closer to the feathering position than the others.

    Abstract: A method is disclosed for controlling a wind turbine rotor during a stop process by pitching the rotor blades fast, e.g. with a angular rate of 10-15°/s to a no-thrust position, after which the rotor blades are pitched to maintain the no-thrust or a thrust against the direction of the pendulum movement of the tower for a while to prevent the aerodynamic thrust from aggravating the pendulum movement of the tower. With this control strategy, the bending moments of the tower root are minimised, leading to avoidance of wind turbine tower failure, to prolongation of the life time for a wind turbine tower and the possibility of erecting wind turbine towers of less reinforcement at the tower root.
