|20130125480||Process and Unit for the Attachment of a Wind Turbine's Tower to a Foundation and Wind Turbine Incorporating Said Unit - The invention describes a process and a unit, both enabling to attach a wind turbine tower to a foundation, as well as describes also a wind turbine incorporating the unit. The process features a stage of installation of a support element for the transmission of stresses from the tower to the foundation, followed by a stage of levelling the support element and pouring foundation concrete up to the support element's lower side so that the lower side is adhered to the poured concrete once it has set. The unit comprises at least one support element.||05-23-2013|
|20120203384||SYSTEM AND PROCESS FOR CONTROLLING ACTIVE POWER IN A POWER GENERATION PLANT - The present invention describes a process for controlling the active power injected into the grid by a generating plant for contributing to the stability of the power grid in the event of frequency variations where, in response to a deviation in grid frequency, each generating unit calculates an active power variation parameter generated based on a first parameter stored in said generating unit, said first parameter being representative of a respective contribution of said generating unit to a required variation in total active power of the generating plant, and where a central control unit of the generating plant connected to each generating unit updates the value of the first parameters when changes are produced therein.||08-09-2012|

|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|

|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|
