| 20120063900 | METHOD FOR EXAMINING AN ELECTRIC ENERGY ACCUMULATOR - The invention relates to a method for examining an electric energy accumulator ( | 03-15-2012 |
| 20120056429 | METHOD OF OPERATING A ROTOR BLADE ADJUSTMENT DRIVE - Disclosed is a method for operating a rotor blade adjustment drive for a wind turbine, in which an electric working load ( | 03-08-2012 |
| 20120043760 | EMERGENCY POWER SUPPLY DEVICE - The invention relates to an emergency power supply device for a rotor blade adjustment system ( | 02-23-2012 |
| 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 |
| 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 |
