Check of the performance and in particular the yaw behaviour of wind turbines
Check of the performance and in particular the yaw behaviour of wind turbines
Site: Small wind farm in the state of Bavaria, Germany
Method:
Wind measurement by Sodar
Analysis of SCADA data of the wind turbines
Results:
The power curves as determined on the turbines are sufficiently in agreement with the warranted levels. However, improvements are possible.
The yaw algorithm of one of the investigated turbines is far from optimal.
A check after a corresponding software change showed a significant improvement.
One of the turbines is on average not aligned optimally with the wind direction. A change would result in an increase of the energy capture by several percent.
In 2019, a wind measurement with a Sodar was completed successfully in the high mountains of Bosnia under winterly conditions.
