Analysis of Traditional Yaw Measurement
In this paper, we look in greater detail at the yaw angle of the turbine relative to the wind.
Key question: Based upon data from the nacelle-mounted measurement system, what are the characteristics of the current yaw measurement system?
Key question: Does the rotating vortex post-rotor have an effect on measurement of yaw
Key question: Can rotor-induced errors in yaw measurements be corrected so that a good control system can be designed?
A Catch the Wind, Inc. (CTW) Optical Control System (OCS), Generation I, is mounted upon an operating utility scale wind turbine. The yaw angle of the turbine is studied in a variety of different ways to better understand the physics of basing control decisions
upon measurements of the post-rotor flow.
