The invention relates to a method for assembling and automatically lifting a wind turbine tower, characterised in that different ferrules (3) composed of wedges (4) are formed in situ using robotised elements (10) that travel along circular guides (9). Welding, inspection and painting elements are simultaneously applied to the inside and outside of the ferrule (3), and work is done at two heights by replicating the circular guides (9) and raising same by means of vertical columns (16). As the ferrules (3) are formed, they are raised by a triangle (6) that travels between columns (5) of the automatic lifting system. Subsequently, by horizontally welding ferrules (3) together, a tower section (2) is formed. The method is applied to tubular towers and frustoconical towers that are 6-8 m in diameter and at least 200 m high.

Resumen de: US20260213545A1
A system and method operate a renewable energy source having an inverter-based resource (IBR) system and controlled by a power converter controller. The IBR system is operated in grid-forming mode (GFM) control. The power converter controller receives a control signal that is derived based on a frequency droop function performed on a detected grid frequency at an upstream controller. The power converter controller generates an output power actuator signal based on a frequency droop function performed on the detected grid frequency at the power converter controller. A first compensation is applied to the upstream controller that reduces or eliminates changes in the control signal received by the power converter controller due to changes in the grid frequency.

Resumen de: WO2025056131A1
The invention relates to adjusting individual pitch of wind turbine rotor blades. The invention involves obtaining an edge load signal indicative of edge loading on the individual rotor blades in a wind turbine rotor rotational frame, removing forward whirling frequency content corresponding to forward whirling motion from the edge signal, and applying a rotor azimuth-based transformation operation to obtain a backward whirling edge signal in a wind turbine rotor azimuth fixed frame. The backward whirling edge signal is split into first and second signals corresponding to disturbances at an edge frequency and at the edge frequency minus 2P, respectively. First and second control actions for mitigating backward whirling motion are applied to the first and second signals, respectively. The resulting signals are transformed back into rotor rotational frame to obtain individual pitch offset values which are then used to adjust pitch of the rotor blades.
