Abstract: A wind turbine (1) comprising a generator (2), an auxiliary system (6) comprising one or more electrical components (7), and an auxiliary transformer (5) having an internal impedance is disclosed. The auxiliary transformer (5) is connected on a primary side to the generator (2) and to a power grid (3), and on a secondary side to the auxiliary system (6). The wind turbine (1) further comprises an overvoltage protection device (8), being electrically arranged on the secondary side of the auxiliary transformer (5), and being arranged to be triggered by a voltage exceeding an overvoltage threshold. The triggering of the overvoltage protection device (8), due to a voltage being above the overvoltage threshold, causes a current exceeding a nominal current through the auxiliary transformer (5) to flow into the overvoltage protection device (8), thus causing a secondary side voltage of the auxiliary transformer (5) to be limited due to the internal impedance of the auxiliary transformer (5).

Abstract: The invention relates to a method for controlling a wind turbine system, more particular for a controlled sliding strategy to lower loads on the yaw system by controlling mechanical brakes and motor brakes in the yaw drive actuators. 5 When the yaw system (300) being in the non-yawing operational state, and the mechanical brake(s) (400) being in an engaged state, and the yaw controller (308) determines or receives a signal indicative of a yaw moment, and if the signal indicative of a yaw moment is above a signal threshold, then the yaw controller (308) sends a braking signal to the yaw drive actuators to enter the 10 motors into the brake state to apply a braking torque.
