20120032442 | BLADE ANGLE ADJUSTMENT DRIVE FOR A WIND POWER PLANT - A blade angle adjustment drive for a wind power plant having an electrical converter, an electric motor electrically coupled to the converter, and a monitoring unit which monitors the operation of the converter and identifies a malfunction in the operation of the converter. The operation of the converter may be interrupted at least temporarily based on the malfunction. An interruption prevention unit is selectively operable to prevent an interruption in the operation of the converter by the monitoring unit when the bade angle adjustment drive is in an emergency operation state. | 02-09-2012 |
20120032627 | BLADE PITCH CONTROLLING DRIVE FOR A WIND TURBINE - The invention relates to a blade pitch controlling drive for a wind turbine, comprising an electrical converter, an electric motor that is electrically coupled to the converter, a monitoring unit operable to monitor an electric output current supplied by the converter to the electric motor and determine a state of the load on the converter as a function of the electrical output current, a current limiting unit operable to reduce a maximum possible output current to a nominal current when the state of the load is an overload state when the nominal current when in a non-overload state, and a peak current control unit that can be activated. When activated, the peak current may be provided as the maximum possible output current, regardless of the load state of the inverter at the time of the activation. | 02-09-2012 |
20120223523 | WIND TURBINE - The disclosure relates to a wind turbine having a machine support ( | 09-06-2012 |
20120224295 | SWITCHGEAR CABINET FOR A WIND TURBINE - The invention relates to a control cabinet for a wind turbine including a cabinet body ( | 09-06-2012 |
20130076174 | ELECTRIC DRIVE ASSEMBLY - The disclosure describes an electric drive assembly having an electric motor which is arranged in a motor housing and a fan which is arranged on an end face of the motor housing. The fan generates a cooling air flow that removes heat from the electric motor. An electronic controller with electronic components controls or regulates the electric motor. A box-shaped motor panel sits on the motor housing and houses the electronic components. The heat generated during operating of the electronic components can be discharged by means of the motor panel to a heat sink which is in thermally conductive contact with the motor panel. | 03-28-2013 |
