Abstract: The present disclosure relates to control of a wind turbine in connection with a low voltage event (35) where the grid voltage drops from a first level and to a second lower level. Upon detection of the termination of the low voltage event (t2), the turbine is operated in a recovery mode (31) where the turbine is operated by use of a control trajectory. The control trajectory being determined by using a model predictive control (MPC) routine.

Abstract: The invention relates to a method for limiting structural loads in a wind turbine in situations where the power produced by the wind turbine is increased or decreased. The limitation of structural loads is achieved by restricting the power ramp rate, i.e. the rate of change of increases or decreases in produced power. The restriction is only invoked if a maximum change of the produced power or the corresponding internal power reference within a time window exceeds a given threshold.

Abstract: The invention relates to a fault ride through method for controlling a wind turbine during a grid fault where the grid voltage drops below a nominal grid voltage. After detection of a grid fault, the total current limit for the power converter output is increased to a total maximum overload current limit. This may allow generation of an increased active current for compensating a reduction in active power. Depending on whether active or reactive current generation is prioritized, an active or reactive current reference is determined initially. The active current reference is determined in a way so that a reduction in active power production due to the grid voltage drop is minimized and based on the condition that the vector-sum of the active output current Iq and the reactive output current Id is limited according to the total maximum overload current limit, and a maximum period of time is determined in which the power converter can be controlled based on the active and reactive current references. Afterwards the power converter is controlled based on the active and reactive current references.

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: A method and associated control arrangement are disclosed for controlling a de-rated power output of a wind turbine generator, where the wind turbine generator is associated with a predetermined power ramp rate upper limit and operating with a de-rated rotor speed. The method includes ramping the power output from an initial power level to a target power level during a ramping interval. During a first portion of the ramping interval, the power output is ramped at a first power ramp rate less than the power ramp rate upper limit. The method further includes ramping the rotor speed to a predetermined rotor speed value contemporaneously with ramping the power output during the first portion of the ramping interval. The first power ramp rate is determined such that a difference between the power output and the target power level is monotonically decreasing during the entirety of the ramping interval.
