    General Electric Renovables Espana SL Submits United States Patent Application for Load Sensors in Wind Turbines

    June 10, 2022 - Electronics Patent News


      Alexandria, June 10 -- General Electric Renovables Espana SL has submitted a patent application for load sensors in wind turbines. This invention was developed by Albisu Iso Efren and Arroyo Beltri Pedro.

      The patent application number is 17/539432. International Patent Classification code is F03D 17/00 20060101 F03D017/00. Cooperative Patent Classification codes are F05B 2270/331 20130101, F05B 2260/83 20130101, F03D 17/00 20160501, F05B 2260/80 20130101 and F05B 2270/808 20130101.

      An abstract released by the U.S. Patent and Trademark Office states: "The present disclosure relates to a method for determining reliability of one or more load sensors in a wind turbine. The method comprises measuring loads with the load sensors during operation of the wind turbine; determining in-plane moments based on the measured loads; selecting the in-plane moments with 1 p frequency; and comparing the selected in-plane moments with theoretical in-plane moments due to a mass of the blade. The method then comprises determining that the load sensors have reduced reliability if the selected in-plane moments deviate from the theoretical in-plane moments by more than a first threshold value. The present disclosure also relates to wind turbine systems incorporating load sensors and methods for on-line determination of correct functioning of load sensors mounted on a wind turbine blade."
