20120321473 | REDUNDANT PITCH SYSTEM - A pitch system for a wind turbine installation having an electrically driven pitch drive associated with each rotor blade and an electric motor arranged in a rotating part of the wind turbine installation for blade adjustments. A power and control unit is associated with the motor and has line connections for the transmission of power and control data from the power and control unit to the motor and vice versa. The line connections are passed via a first rotating bushing arranged at a connecting point between the rotating part and an axially adjacent stationary region. The pitch system also includes second rotating bushing which operates mechanically and electrically separately from the first rotating bushing and is connectable to the power and control unit and to the motor for maintaining reliable transmission of the power and control data if the first rotating bushing fails. | 12-20-2012 |
20130015662 | CONTROL DEVICE FOR A WIND TURBINEAANM Bertolotti; FabioAACI Bad BentheimAACO DEAAGP Bertolotti; Fabio Bad Bentheim DEAANM Van Schelve; JensAACI SchuttorfAACO DEAAGP Van Schelve; Jens Schuttorf DE - The invention relates to a control device for a wind power plant having an electrical system and a rotor including a plurality of rotor blades driven by wind, and outputting a mechanical rotor power to the electrical system. The system converts the mechanical rotor power at least partially into electrical power. The control device includes a blade sensor associated with at least one of the rotor blades and measuring at least one physical property of the rotor blade dependent on at least one characteristic value of a wind field describing the wind at the location of the rotor. The blade sensor generates a blade sensor signal characterizing the physical property. The control device also includes an estimation unit to determine an estimated value for the electrical power as a function of the blade sensor signal. | 01-17-2013 |
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 |

20140156221 | ANGULAR POSITION ENCODER FOR A ROTATING SHAFT - An angular position encoder for a rotating shaft is disclosed, in particular for application on the rotor shaft in wind turbines. A materialized measure in the form of a roller chain is arranged around the circumference of the shaft. A scanning head in the form of a sensor is arranged at a distance from the materialized measure and scans the surface of the materialized measure as the shaft is rotating. A measurement value evaluation unit processes recorded measurement values to give positional and/or speed data on the shaft. A method for determination and measurement of the rotor speed or position for a rotating shaft by means of the angular position encoder is also disclosed which includes determination and measurement of the rotor speed or position, creating or mapping at least one reference pattern or map of the chain, and a comparing the pattern and an actual measurement value. | 06-05-2014 |
