DTU - National Test Centre for Large Wind Turbines
- National test centre for large wind turbines, Høvsøre, Jutland Denmark.
- Active since 2004, and has delivered high quality wind data from 10 meters height to 165 meter.
- The data are used by DTU and partners, and has already given important information about the wind distribution above 100 meter height, and the impact on wind turbines.
In addition to the infrastructure needed for the commercial wind turbine testing, the test site also include 2 met-masts;
One is 114 meters high and is instrumented with following instrumentation:
- Cup wind speed and sonic in 6 heights
- Wind direction and absolute temperature in 3 heights
- Pressure and Relative humidity in 2 heights
- Precipitation and Radiation
The second mast is 165 meters high and is instrumented with following instrumentation:
- Cup wind speed and Wind direction in 3 heights
- Sonic in 2 heights
On the ground a Ceilometer measures the height of the cloud base
DTU is planning to make an extension of the test station at Østerild, Jutland Denmark, where two 250 meters high met masts, each intensely instrumented are planned.
- We offer evaluation and consulting to new wind measurement methods including inter calibrations of instruments, and the Høvsøre database is a valuable dataset giving information about the wind distribution and the addition of data from the Østerild site will make it even more valuable.
- DTU has a large experience in developing and evaluating new wind measurement methods using the input from the met masts. Currently the met masts are used intensively for inter calibration of lidar’s and DTU can through this facility contribute to the development of a generalised and later accredited procedure.
