Patent number: 11408396Abstract: A wind turbine and method are provided for defining a plurality of thrust limits for the wind turbine located at a site and having a rotor with rotor blades, wherein the thrust limits define values of aerodynamic thrust on the rotor not to be exceeded in operation. The method includes providing a wind speed distribution representative for the site and defining one or more isolines of constant turbulence probability representing a turbulence parameter as a function of wind speed. The isolines correspond to quantile levels of turbulence of the wind speed distribution and the turbulence parameter is indicative of wind speed variation. The turbulence parameter is determined by continuously measuring wind speed upstream of the rotor with an active sensing system and calculating the wind speed variations from the measured wind speed. Turbulence ranges are defined with respect to the isolines and thrust limits are defined for the turbulence ranges.Type: GrantFiled: January 8, 2021Date of Patent: August 9, 2022Assignee: General Electric Renovables Espana, S.L.Inventors: Pierino Gianni Bonanni, Xu Fu, Francesco Perrone

Publication number: 20210317818Abstract: A method for reducing extreme loads acting on at least one rotor blade of a wind turbine includes calculating, via a processor, a flapwise bending moment of the rotor blade(s). Further, the method includes calculating, via the processor, an edgewise bending moment of the rotor blade(s). The method also includes calculating, via the processor, an average load envelope of a blade root bending moment of the rotor blade(s) as a function of the flapwise bending moment and the edgewise bending moment of the rotor blade(s). Moreover, the method includes calculating, via the processor, an overall load envelope of the blade root bending moment of the rotor blade(s) as a function of the average load envelope and a future load estimation of the blade root bending moment of the rotor blade(s). As such, the method also includes implementing, via the processor, a control action when the overall load envelope is above a certain threshold.Type: ApplicationFiled: April 9, 2020Publication date: October 14, 2021Inventors: Francesco Perrone, Leonardo Cesar Kammer

Publication number: 20200347822Abstract: A method for defining a plurality of thrust limits for a wind turbine having a rotor with a plurality of blades and being located at a site. The thrust limits define values of aerodynamic thrust on the rotor not to be exceeded in operation. The method comprises providing a wind speed distribution representative for the site, and defining a plurality of isolines of constant turbulence probability representing a turbulence parameter as a function of wind speed. The turbulence parameter is indicative of wind speed variation. The isolines correspond to quantile levels of turbulence of the wind speed distribution. Turbulence ranges may be defined with respect to the isolines and thrust limits can be defined for the turbulence ranges. The disclosure also relates to methods of operating wind turbines using thrust limits and to wind turbines with suitable control systems.Type: ApplicationFiled: March 3, 2020Publication date: November 5, 2020Inventor: Francesco Perrone

Patent number: 10324207Abstract: Computing device, computer instructions and method for calculating an image of a subsurface based on least square migration and image de-convolution using a matching operator F. The method includes receiving seismic data d; computing a first image m of the subsurface based on the seismic data d; computing a second image h of the subsurface based on the first image m; applying a transform operation to the first and second images m and h to obtain a first transform of the first image and a second transform of the second image; calculating the matching operator F by matching the first transform of the first image to the second transform of the second image; and generating an updated image mupdated of the subsurface based on the matching operator F and the first transform of the first image.Type: GrantFiled: October 28, 2016Date of Patent: June 18, 2019Assignee: CGG SERVICES SASInventors: Adel Khalil, Henning Hoeber, Jeshurun Hembd, Adriano Gomes, Gordon Poole, Francesco Perrone, Lorenzo Casasanta, Graham Roberts, Andrew Ratcliffe

Publication number: 20180335531Abstract: A method for obtaining an image of an explored subsurface formation. The method includes receiving seismic data, wherein the seismic data is associated with a source or a seismic sensor placed in a well; forward propagating a first wavelet from the source using a first velocity model; backward propagating a second wavelet from the seismic sensor using a second velocity model, which is different from the first velocity model; and applying an imaging condition to the forward propagated first wavelet and the backward propagated second wavelet to calculate a reflectivity of the subsurface.Type: ApplicationFiled: May 4, 2018Publication date: November 22, 2018Inventors: Andrew RATCLIFFE, Francesco PERRONE, Graham ROBERTS, Martin CHAPPELL

Patent number: 9702997Abstract: An objective function is disclosed that extracts the velocity error information directly in the image domain without computing common-image gathers. Because of the dimensionality of the problem, gradient-based methods (such as the conjugate-gradient algorithm) are used in the optimization procedure. In order to include the full complexity of the wavefield in the velocity estimation algorithm, a two-way (as opposed to one-way) wave operator is considered, where the imaging operator is not linearized with respect to the model parameters (as in linearized wave-equation migration velocity analysis), and the gradient of the objective function is determined using the adjoint-state method. The velocity estimation methodology is illustrated with a few synthetic examples.Type: GrantFiled: July 12, 2012Date of Patent: July 11, 2017Assignee: Colorado School of MinesInventors: Paul Sava, Francesco Perrone, Clara Andreoletti, Nicola Bienati
