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.

Oldershausen, 15 May 2018: A new study of aj shows that the wind resource of the years around 1990 cannot be considered as very exceptional any more. Consequently, these years must be included in the long term reference period, if the result should be balanced. Download of the report Wind D NAO-Index E 15.05.2018 aj
