Summary: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. Equipo para la estimación de demandas de ángulo de pitch o velocidades de ángulo de pitch independiente para cada pala en aerogeneradores, para incorporarse accesoriamente en relación con el sistema de control (3) propio del aerogenerador de aplicación, comprendiendo un sistema de medición (1) y un autómata (2), incluyendo el sistema de comunicaciones (1) un conjunto de sensores (4) que se disponen sobre las palas del aerogenerador, mientras que el autómata (2) comprende un módulo (8) que en función de la información del sistema de medición (1) realiza un cálculo de control individual de pitch de cada pala, generando una señal para que el PLC (9) del sistema de control (3) del aerogenerador transmita una orden para que unos actuadores (10) hagan girar a las palas individualmente en torno a su eje longitudinal.
