Title:
YAW SYSTEMS AND METHODS
Document Type and Number:
Japanese Patent JP2022166830
Kind Code:
A
Abstract:
To provide a method of finding good equilibrium for a yaw system between avoiding excessive operation of the yaw system and optimizing power output of a wind turbine.SOLUTION: The present disclosure relates to methods which comprise receiving a wind direction signal indicative of an instantaneous wind direction at a wind turbine, filtering the wind direction signal to determine a filtered wind direction signal, and determining a yaw error signal of the wind turbine indicating a difference between a yaw angle of the wind turbine and the instantaneous wind direction indicated by the filtered wind direction signal. The methods further comprise determining a control signal for a yaw system of the wind turbine based on the yaw error signal. Filtering the wind direction signal comprises applying a low pass filter with a variable time constant, where the variable time constant is dependent on a wind condition. The present disclosure further relates to control systems for wind turbines which are configured to implement such methods. The present disclosure further relates to methods of operating wind turbines.SELECTED DRAWING: Figure 6
