| 20100298991 | SYSTEM AND METHOD FOR CONTROLLING A WIND FARM - System and method for controlling a wind farm, for wind farms comprising a plurality of wind turbines having a rotor, a generator, a control unit and means for connecting to the mains of the wind farm, said wind turbines having means for generating reactive power according to the instructions of the wind farm control system, said control system calculating a global reactive power demand to be produced by the whole wind farm on the basis of the voltage at the connection point or the power factor required, and said control system sending reactive power instructions to the wind turbines of the farm, the central control system for the wind turbines receiving information based on one or more parameters indicating the level of heating of the electrical components of the wind turbines, the generation of reactive power being distributed between the various wind turbines. | 11-25-2010 |
| 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 |
| 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 |
| 20130318789 | SYSTEM AND METHOD FOR ASSEMBLING AND DISASSEMBLING COMPONENTS FROM A WIND POWER TURBINE - A method and system is provided for assembling or disassembling a blade of a wind turbine. The wind turbine includes a tower resting on a base, a rotor including at least one rotor blade having a blade connection flange and a nacelle mounted atop the tower, a hub rotatably connected to the nacelle and including a hub connection flange adapted to be detachably connected to a blade connection flange of a rotor blade. Thy wind turbine further includes a first positioning element adapted to be attached to the nacelle or to the tower in a top area and a second positioning element adapted to be joined to the blade in a root blade area, where the first and second positioning elements are configured to cooperate to provide an accurate position of the blade connection flange prior to connection to the hub connection flange. | 12-05-2013 |
| 20140175038 | WIND TURBINE ASSEMBLY SYSTEM - The wind turbine assembly system of the present invention comprises a lifting structure comprising at least first structural support elements configured to transmit stresses to the wind turbine tower during the hoisting of a wind turbine component and a crane configured to displace the wind turbine component towards the tower axis, the system further comprising a displaceable climbing element with respect to the lifting structure by means of guiding mechanisms, the displaceable climbing element incorporating second structural support elements dimensioned to at least partly support the weight of the lifting structure, where the first structural support elements are displaceable so that their relative position can vary with respect to the lifting structure. | 06-26-2014 |
| 20140346778 | ROTARY ELECTRIC GENERATOR STATOR, ROTARY ELECTRIC GENERATOR COMPRISING SAID STATOR AND WIND TURBINE INCORPORATING SAID ROTARY ELECTRIC GENERATOR - It allows a more complete cooling of the generator, comprising: a magnetic core with a crown ( | 11-27-2014 |
| 20150020467 | PRECAST SEGMENT FOR WIND TURBINE TOWER AND METHOD FOR BUILDING A WIND TURBINE TOWER USING SAID PRECAST SEGMENT - Precast segment for wind turbine tower especially designed to be used in wind turbine towers installed in cold climates, and which comprises joint flanges showing a configuration intended to establish the boundaries for forming the joints between said precast segment and an adjacent precast segment and which comprises conduits provided with an inlet and an outlet, situated in the proximity of the joint flanges of the precast segment intended to house some heating cables that generate heat. The method comprises the use of the described precast segment and the stages of introducing heating cables in the conduits of the precast segment, applying current to said cables and removing the cables when a filler material used in the joint between precast segments has set. | 01-22-2015 |
| 20150096240 | PRECAST CONCRETE DOWEL, WIND TURBINE TOWER COMPRISING SAID DOWEL, WIND TURBINE COMPRISING SAID TOWER AND METHOD FOR ASSEMBLING SAID WIND TURBINE - It allows simplificating the assembling of a wind turbine ( | 04-09-2015 |
