[A] wind turbine [whose] rotor revolutions are [kept] even by adjusting the blade angle.  11, record 1, English, - pitch%2Dregulated%20wind%20turbine

Record number: 1, Textual support number: 1 OBS

In the case of a system with blade-angle adjustment, the electronic controller constantly measures the system’s power output. If this is too high, a command is sent to the blade-adjusting system with the result that the rotor blades are moved slightly out of the wind. When the wind drops, the blades are turned into the wind. It must therefore be possible to turn the rotor blades around their own longitudinal axis.  11, record 1, English, - pitch%2Dregulated%20wind%20turbine

Éolienne à axe horizontal dont le rotor est muni de pales inclinables qui permettent leur ajustement en fonction de la direction du vent, selon le système de contrôle par calage variable de pale.  4, record 1, French, - %C3%A9olienne%20%C3%A0%20pas%20variable

Record number: 1, Textual support number: 1 CONT

Sur une éolienne contrôlée à calage variable (appelée aussi une éolienne à pas variable), le contrôleur électronique vérifie plusieurs fois par seconde la puissance de sortie de l'éolienne. En cas de puissance de sortie trop élevée, le contrôleur électronique de l'éolienne envoie une commande au dispositif de calage qui pivote immédiatement les pales légèrement sur le côté, hors du vent. Inversement, les pales seront pivotées de manière à pouvoir mieux capter de nouveau l'énergie du vent, dès que le vent aura baissé d'intensité.  3, record 1, French, - %C3%A9olienne%20%C3%A0%20pas%20variable

Pitch Regulation. Once the rated wind speed has been reached, a WT [wind turbine] will be unable to make use of all of the wind energy incident on the rotor plane and must shed some. A pitch-regulated WT [wind turbine] will do this [namely] by pitching the blades to increase the angle of attack to cause sections of the blade to stall(in pitch-to-stall machines).  4, record 2, English, - fixed%2Dpitch%20wind%20turbine

stall regulation. The blades on a stall-regulated-WT [wind turbine] cannot be pitched. To achieve control of power captured above rated wind speed, the blades are carefully designed so that they progressively stall starting at the blade root and moving out towards the tip as the wind speed increases further. Stall-regulated WTs will respond much more quickly to gusts than pitch-regulated WTs(where mecanic pitch adjustments take finite amounts of time to effect), improving the power quality output by the WT above rated wind speed.  1, record 3, English, - stall%2Dregulated%20blade

Pitch Regulation. Once the rated wind speed has been reached, a WT [wind turbine] will be unable to make use of all the wind energy incident on the rotor plane and must shed some. A pitch-regulated WT will do this [namely] by pitching the blades to reduce the angle of attack and thus the torque and power captured(in pitch-to-feather machines)...  4, record 4, English, - pitch%2Dto%2Dfeather%20machine
