Luis DIEZ-MAROTO 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).

  • Static exciter system for generators
    Patent number: 9735719
    Abstract: The present invention relates to the field of generator technology. It is an object of the invention to control the stability in an electric grid in which a plurality of generators are connected providing electric power to the grid. A static exciter system includes a control device for controlling the field voltage of the field winding of at least two generators connected to a grid system via a busbar.
    Type: Grant

  • Static exciter of a field winding and method for operating the same
    Patent number: 8624563
    Abstract: A static exciter of a field winding includes a rectifier connected to an electric grid and to the field winding; a unidirectional electronic switch connected in series with the rectifier; a capacitor bank; and a further switch disposed between the unidirectional electronic switch and the capacitor bank. Exciter also includes a control unit connected to the further switch and configured to close the further switch when a grid voltage drops below a first prefixed voltage value so as to connect the capacitor bank to the field winding and configured to open the further switch when the grid voltage exceeds a second prefixed voltage value so as to disconnect the capacitor bank from the field winding and so as to supply energy to the field winding from the capacitor bank for a time period.
