Erik Carl Miranda has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8128362
    Abstract: A method of operating a wind turbine above a predefined wind velocity comprising the step of operating a control parameter of the wind turbine within a tolerance band from a reference set-point curve of that control parameter. A wind turbine and a cluster of wind turbines is also contemplated.
    Type: Grant
    Filed: October 23, 2009
    Date of Patent: March 6, 2012
    Assignee: Vestas Wind Systems A/S
    Inventors: Brian W. Andersen, Erik Carl Miranda
  • Patent number: 8096762
    Abstract: A wind turbine is presented where the operation lifetime of the main bearing is extended by relieving the main bearing by reducing the mean bending moment on the bearing by means of individual pitch control of the blades of the rotor so as to create an aerodynamic mean tilt moment on the rotor by means of aerodynamic forces on the blades, the tilt moment at least partly counteracting the bending moment caused by the overhang load forces on the main bearing from the gravitational pull on the rotor mass.

  • Patent number: 7898100
    Abstract: A method of operating a pitch controlled wind turbine connected to the utility grid in response to an increase in wind velocity to above a predefined value. The method includes the sequential steps of: reducing the generated power, allowing an intermediate increase in the generator speed, and reducing the generator speed by pitching the wind turbine rotor blades. A wind turbine and a cluster of wind turbines is also contemplated.
