Title (EN) WIND TURBINE VARIABLE-PITCH CONTROL METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE COMMANDE DE PAS VARIABLE D'ÉOLIENNE
(ZH) 风力发电机组变桨控制方法及装置
Abstract:
(EN) A method and a device for use in variable-pitch control of a wind turbine, in said method: if a current wind speed is continuously maintained at a small wind speed, then periodically detecting whether a maintained duration of a current pitch angle of a wind turbine reaches a preset duration; once the preset duration is reached, switching a current minimum pitch angle to another minimum pitch angle.
(FR) L'invention concerne un procédé et un dispositif destinés à être utiliser dans la commande de pas variable d'une éolienne. Dans ce procédé : si une vitesse de vent courant est maintenue petite en continu, alors détecter périodiquement si une durée maintenue d'un angle de pas courant d'une éolienne a atteint une durée prédéterminée; une fois la durée prédéterminée atteinte, à commuter un angle de pas minimal courant à un autre angle de pas minimal.
(ZH) 一种风力发电机组变桨控制方法及装置,该方法中,若当前风速持续维持在小风速状态下,则周期性地检测机组当前的桨距角的维持时长是否达到预设时长,每当达到预设时长,便将当前的最小桨距角切换为另一最小桨距角。
