Abstract

Dispositivo de ajuste (1) para una pala de rotor (6) de un rotor (5) de una turbina eólica (2), - comprendiendo el rotor (5) 5 un cubo (8) y al menos una pala de rotor (6), - pudiendo la pala de rotor (6) montarse en un cojinete (9) que se puede montar entre la pala de rotor (6) y el cubo (8), - y pudiendo la pala de rotor (6) disponerse de manera giratoria alrededor de un eje de pala (7) que discurre en la dirección axial de la pala de rotor (6) en diferentes posiciones de ataque en el cubo, - comprendiendo el dispositivo de ajuste (1) un motor de ajuste (10) para accionar y/o fijar la pala de rotor (6), un primer dispositivo (11) para determinar una posición de pala y un convertidor (13) para activar el motor de ajuste (10), - teniendo el convertidor (13) al menos una unidad de control (14), caracterizado por que - el primer dispositivo (11) tiene al menos dos medios (15a, 15b) para generar en cada caso una señal eléctrica (S1a, S1b) que depende de la posición de ataque, - la unidad de control (14) y/o la unidad de evaluación (16) tienen al menos una entrada de señal conectada con una salida de señal de los medios (15a, 15b), - la unidad de control (14) se puede conectar con al menos una unidad de evaluación (16) para comprobar una redundancia de las señales eléctricas (S1a, S1b) de los al menos dos medios (15a, 15b) y para comparar las señales (S1a, S1b) de los al menos dos medios (15a, 15b) o de un derivado de las señales (S1a, S1b) con al menos un valor umbral (λ) almacenado, - y la unidad de control (14) y/o la unidad de evaluación (16) están configuradas de modo que, en caso de superarse un primer valor umbral (λ1), se finaliza una operación de ajuste de pala.
