DEVICE FOR ESTIMATING DEMANDS FOR PITCH ANGLE OR INDEPENDENT PITCH ANGLE VELOCITY FOR EACH BLADE IN WIND TURBINES

摘要

Device for estimating demands for pitch angle or independent pitch angle velocities for each blade in wind turbines, in order to be accessorily incorporated in relation to the very control system (3) of the wind turbine being used, comprising a measuring system (1) and a robot (2), with the communication system (1) including a set of sensors (4) which are arranged on the blades of the wind turbine, while the robot (2) comprises a module (8) which, on the basis of the information from the measuring system (1), carries out an individual pitch control calculation for each blade, generating a signal so that the PLC (9) of the control system (3) of the wind turbine transmits a command so that actuators (10) cause the blades to rotate individually around the longitudinal axis thereof.
