    摘要： A rotational positioning system in a wind turbine is provided that comprises a driven part (101), a plurality of positioning drives (102) coupled to the driven part (101), a plurality of sensors (111) each arranged to sense a load parameter indicative of the load of the respective positioning drive (102), and a load controller (112, 113, 114, 115) connected to the plurality of sensors (111). The load controller (112, 113, 114, 115) is arranged to determine a load of a respective positioning drive (102) based on the sensed load parameter, to compare said load with an expected load value, and to output a signal (115) indicative of a failure of the respective positioning drive (102) in response to the load being smaller than the expected load value.

    摘要： A yaw system of a wind turbine includes a plurality of motors, each motor being coupled to the nacelle for applying torque to the nacelle; a plurality of controllers, one controller for each of the motors, each controller being configured to control the respective motor and coupled to at least one other controller to transmit operation information thereto; and a yaw system controller configured to transmit control information to at least one controller of the plurality of controllers. At least one of the controllers is configured to control the respective motor based on at least one of the control information and the received operation information from the at least one other controller. Communication between the controllers of the respective motors can allow a faster response of the yaw system to yaw the nacelle according to a change of wind direction.

    摘要： A wind turbine arrangement comprises a main wind turbine and at least one secondary wind turbine. The main wind turbine is arranged to produce electrical power and to supply produced electrical power to an external power recipient, such as a power grid. The main wind turbine comprises one or more power consuming internal systems, e.g., yaw system, control system, heating systems, lubrication systems, etc. The secondary wind turbine (s) is/are arranged to produce electrical power and to supply produced electrical power to at least some of the power consuming internal system(s) of the main wind turbine. The secondary wind turbine(s) is/are electrically disconnected from the external power recipient. The secondary wind turbine(s) may constitute a backup power supply to the internal systems. Thereby it is not necessary to refuel the backup power supply, and the backup power supply is environmental friendly. This is particularly useful in offshore wind turbine arrangements.
