"Method For Operating A Wind Turbine, Method For Determining The Temperature Of A Permanent Magnet And Controller For A Wind Turbine"
Abstract: The disclosure concerns a method for operating a wind turbine (100) having an electrical system, the electrical system comprises a permanent magnet generator (130, 300, 400) having a rotor (310, 410) and a stator (320, 420), and a power electronic device (170, 180, 190, 200) electrically connected to the permanent magnet generator, wherein the power electronic device and a circuit breaker (190) are electrically disposed in series between the permanent magnet generator and a grid (210), wherein the permanent magnet generator has permanent magnets and a generator winding (322, 324, 326, 422, 424, 426) into which a voltage is induced by the permanent magnets when the rotor is rotating, the method comprising: generating a signal for tripping the circuit breaker based on a field modification that is modifying the field of the permanent magnets (312, 314, 412, 414) of the permanent magnet generator. Further the disclosure concerns, a controller (220) for a wind turbine (100), the wind turbine comprising an electrical system having a permanent magnet generator (130, 300, 400) having a rotor (310, 410) and a stator (320, 420), and a power electronic device (170, 180, 190, 200) operatively connected to the permanent magnet generator, and a circuit breaker (190) electrically disposed in series between the permanent magnet generator and a grid (210), wherein the permanent magnet generator has permanent magnets a generator winding (322, 324, 326,422, 424, 426) into which a voltage is induced by the permanent magnets when the rotor is rotating, wherein the controller is further adapted to be connected to a control circuit of the circuit breaker, wherein the controller is adapted to generate a signal for tripping the circuit breaker based on the field modification of the magnetic field of the permanent magnets (312, 314, 412, 414) of the permanent magnet generator.
