Patent Images
1. A method for determining a yaw direction of a wind turbine comprising:
- activating, by a processor of a computing system, a receiver coupled to the wind turbine to receive a signal broadcasted from a source, wherein the receiver is synchronized with a transmitter associated with the source, such that the receiver is activated at a same time interval as the transmitter when the transmitter transmits the signal;
applying, by the processor, a Pseudo-Doppler Radio Direction Finding based on the signal received by the receiver;
acquiring, by the processor, as a function of applying the Pseudo-Doppler Radio Direction Finding, a direction from the receiver towards the source, and an offset angle;
determining, by the processor, the yaw direction of the wind turbine, using the offset angle and the direction from the receiver towards the source.
