PITCH-REGULATED ROTOR [3 records]

Record 1 2013-06-26

English

Subject field(s)
  • Electric Rotary Machines - Types
  • Wind Energy
DEF

[A horizontal axis wind turbine] where the global pitch angle [of the blades] does not change dynamically ...

CONT

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).

French

Domaine(s)
  • Machines tournantes électriques - types
  • Énergie éolienne
DEF

Éolienne à axe horizontal dont le rotor est muni de pales fixées de manière rigide au moyeu et qui est régulée soit par effacement du rotor, soit par décrochage aérodynamique passif des pales.

Record 2 2006-06-01

English

Subject field(s)
  • Stators and Rotors (Electrical Components)
  • Electric Rotary Machines - Types
  • Wind Energy
DEF

A wind turbine rotor that varies blade pitch to regulate lift and, hence, torque and power.

Key term(s)
  • pitch regulated rotor
  • pitch controlled rotor
  • variable-pitch rotor

French

Domaine(s)
  • Stators et rotors (Composants électrotechniques)
  • Machines tournantes électriques - types
  • Énergie éolienne
DEF

Rotor d'éolienne qui permet de varier le pas des pales afin de contrôler la portance et conséquemment, le couple et la puissance.

Record 3 2005-11-16

English

Subject field(s)
  • Electric Rotary Machines - Types
  • Wind Energy
CONT

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)...

French

Domaine(s)
  • Machines tournantes électriques - types
  • Énergie éolienne
OBS

régulation par mise en drapeau : régulation par variation de calage de pale qui consiste à augmenter l'angle de calage des pales du rotor éolien, entraînant ainsi la diminution de l'angle d'incidence des pales et de la diminution de la surface des pales babayées par le vent.
