Abstract

Un sistema sensor (50) para la monitorización de la desviación de palas de turbina (22) de una turbina eólica (10), que incluye una pluralidad de palas de turbina montadas en un buje (20) del rotor soportado por una góndola (16) encima de una torre (12), comprendiendo dicho sistema: un primer componente (52) configurado en cada una de las palas de la turbina; y un segundo componente (58) configurado en la torre a una altura para detectar la presencia de dicho primer componente cuando las palas giran más allá de la torre y generar un parámetro medible correspondiente, estando dicho segundo componente dispuesto sustancialmente completamente alrededor de la circunferencia de la torre para detectar dichos primeros componentes en cualquier posición de giro de la góndola respecto a la torre. caracterizado porque: dicho primer componente (52) comprende una fuente magnética (56) unida a cada una de las palas (22) de la turbina, y comprendiendo dicho segundo componente (58) una bobina detectora (62) formada alrededor de la torre (12), induciendo dichas fuentes magnéticas una corriente detectable en dicha bobina detectora cuando dichas fuentes magnéticas pasan por dicha bobina detectora dentro de una distancia (42) definida entre las palas y la torre.
