(54) Title (JA):

(57) Abstract:

(EN): A blade pitch angle control device comprising a storage unit (10) for storing, mutually associated with each other, specifiedparameters affecting a variation in blade load, an azimuth angle, and a pitch angle instruction value, an azimuth angle detector (11)

for detecting an azimuth angle for each blade, a parameter detector (12) for detecting specified parameters, an instruction value

acquiring unit (13) for acquiring, for each blade, a blade-based azimuth angle detected by the azimuth angle detector (11) and a

pitch angle instruction value selected by specified parameters detected by the parameter detector (12) respectively from the storage

unit (10), and a pitch angle control instruction value generating unit (14) for generating a pitch angle control instruction value that

is used to individually control a blade pitch angle based on a pitch angle instruction value and a common pitch angle instruction

value.

(FR): L'invention porte sur un dispositif de contrle de l'angle d'inclinaison d'une pale comprenant une unit de stockage(10) pour le stockage mutuel de paramtres dtermins affectant une variation de la charge de la pale, un angle azimutal et

une valeur d'instruction de l'angle d'inclinaison, un dtecteur (11) de l'angle azimutal de chaque pale, un dtecteur (12) des

paramtres dtermins, un module d'acquisition (13) de valeur d'instruction, pour chaque pale, un angle azimutal de pale dtect

par le dtecteur (11) et une valeur d'instruction d'angle d'inclinaison slectionne par des paramtres dtermins dtects par le

dtecteur correspondant (12) partir de l'unit de stockage (10) et un gnrateur de valeur d'instruction d'angle d'inclinaison (14),

ladite valeur tant utilise pour contrler individuellement un angle d'inclinaison de base sur la base d'une valeur d'instruction

d'inclinaison de pale et d'une valeur d'instruction d'inclinaison commune.(JA): ()()()()()()()()
