Title
(EN) CONTROL OF A WIND TURBINE WITH A FAULT CONDITION
(FR) COMMANDE D'UNE ÉOLIENNE PRÉSENTANT UN ÉTAT DE DÉFAILLANCE
Abstract
(EN)
The present invention relates to control of wind turbines in a situation where a fault condition is detected. Control of a wind turbine is described where a control trajectory and a safe-mode trajectory are calculated based on the current operational state of the wind turbine. If the fault condition is detected the wind turbine is controlled using the safe-mode trajectory, otherwise, the normal operation of the wind turbine is continued where the wind turbine is controlled using the control trajectory.
(FR)
La présente invention concerne la commande d'éoliennes dans une situation où un état de défaillance est détecté. La commande d'une éolienne est décrite selon laquelle une trajectoire de commande et une trajectoire de mode sécurisé sont calculées sur la base de l'état de fonctionnement actuel de l'éolienne. Si l'état de défaillance est détecté l'éolienne est commandée à l'aide de la trajectoire du mode sécurisé, sinon, le fonctionnement normal de l'éolienne est maintenu et l'éolienne est commandée à l'aide de la trajectoire de commande.
