French term or phrase: grilles d’aubes de déviation
Dans les inverseurs à grilles, par exemple, les capots mobiles coulissent le long de rails de manière à ce qu’en reculant lors de la phase d’ouverture, ils découvrent des grilles d’aubes de déviation disposées dans l’épaisseur de la nacelle. Un système de bielles relie ce capot mobile à des portes de blocage qui se déploient à l’intérieur du canal d’éjection et bloquent la sortie en flux direct. Dans les inverseurs à portes, en revanche, chaque capot mobile pivote de manière à venir bloquer le flux et le dévier en étant ainsi actif dans cette réorientation.

deviation blade grids


Explanation:
''. In another patent, participation in primary and secondary regulation is achieved by using blade pitch control to specify a percentage of available power as an active power reserve, which can be changed up or down in response to grid frequency fluctuations [34]. Methods for providing active power control of entire wind plants have also been developed. Performing active power control collectively across a wind plant is intended to provide faster response and recovery to grid frequency deviations than can be achieved by performing active power control on individual turbines separately.''

Example sentence(s):
  • These could arise after that the excitation frequency or blade deviation is increased, optimally both.
  • The grid has five blades in total, three of them are driven by force control using three shakers. The deviation as well as force response is measured by strain gauges and dynamometers.
