| 20120038169 | ELECTRIC GENERATOR AND PROCESS FOR ASSEMBLING A WIND TURBINE EQUIPPED WITH SAID GENERATOR - Disclosed herein is a generator having a rotor which comprises rotor excitation element-carrying modules, for example magnets, radially movable in relation to the generator shaft in such a manner, when in their retracted position, as to significantly ease generator transport and assembly. The use of these movable magnet-carrying modules is particularly useful in direct drive-type generators which do not require a multiplier. Another object of the invention is an assembly process which comprises a generator equipped with said radially movable magnet-carrying modules. | 02-16-2012 |
| 20110239563 | WIND GENERATOR TOWER AND PROCESS FOR ASSEMBLY THEREOF - The present invention provides a wind generator tower and a process for assembly thereof. A truncated conical tower assembled from reinforced concrete modules disposes of a tensioning system which provides greater resistance to the same and, in turn, the joints defined between the modules which form the tower are sealed. | 10-06-2011 |
| 20110091287 | SUPPORTING ELEMENT FOR AN OFFSHORE WIND TURBINE, PRODUCTION METHOD THEREOF AND METHOD FOR INSTALLING SAME - The invention relates to a supporting element ( | 04-21-2011 |
| 20100241280 | WIND TURBINE CONTROL - Wind turbine control may be provided. First, a control parameter indicative of foreseeable fluctuations in a rotational speed of a rotor due to wind turbulence may be obtained. The first control parameter may be calculated based on a first signal indicative of a wind power and a second signal indicative of wind turbulence intensity. Then, the control parameter may be compared with a threshold value. Next, a maximum power to be generated by the wind turbine may be reduced if the control parameter exceeds said threshold. | 09-23-2010 |
| 20100237834 | POWER GENERATION PLANT VOLTAGE CONTROL - A method for controlling a power generation plant may be provided. First, an equivalent grid voltage may be estimated based on electric magnitudes measured at a connection point of the power generation plant and an equivalent model of a power grid to which the power generation plant is connected. Then, on the basis of said estimated equivalent voltage, a command indicative of reactive power to be produced by the power generation plant may be generated. | 09-23-2010 |
| 20100219634 | WIND TURBINE CONTROL METHOD, CONTROL UNIT AND WIND TURBINE - A wind turbine control method for dampening vibrations of a transmission system, even in the presence of voltage dips and in any event that is susceptible to reducing active current generation capacity, is provided. First, for example, an initial torque or power instruction may be calculated based on a turbine operating state. Next, a torque or power adjustment term associated with dampening vibration modes of a turbine transmission system may be calculated. Then, a final torque or power instruction may be calculated by, for example, applying the adjustment term to the initial instruction. Finally, the final torque or power instruction may be transformed into a current instruction for controlling the wind turbine. | 09-02-2010 |
