Title:
A WIND TURBINE AND A METHOD OF OPERATING THE WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2020/238693
Kind Code:
A1
Abstract:
The invention relates to a control method and a wind turbine (1), comprising a vibration sensor (13) for measuring a vibration signal of the wind turbine (1) and a controller (15) receiving the vibration signal. The controller (15) calculates a fatigue load parameter and determines an operational limit parameter (20) for a particular operational parameter (22) based on the fatigue load parameter. The controller (15) further determines a control signal according to the operational parameter (22). If the operational parameter (22) exceeds the operational limit, then the operation mode of the wind turbine (1) is modified to bring the operational parameter (22) within safe limits again.
