How efficient is a wind-farm based on the measured data?

The estimated wind-farm efficiency based on the measured data was 90%, whereas that predicted by the WAsP model was 86%. This discrepancy reveals that the modeling time was independent of the wind-farm power production, and that the actual produced power was 5.7% more than the power estimated by the power curve.

Where can I find wind farm data?

Globalwindatlas.info: Free web-based wind data available worldwide, using re-analysis data and mesoscale modelling with great potential for identifying new areas for wind farm development. Edp.com: Open-access wind farm data for one site in Portugal, including failure log. Gain access to our operational and meteorological offshore wind farm data.

How can a wind farm be used for research?

Data from SCADA systems are also routinely collected for wake analysis. In modern wind-field experiments, the resolution of the wind-speed and wind-direction measurements can fulfil research needs, reaching 0.1 m/s and 1°, respectively. Most of the tested wind farms are located on flat terrain; only a few are located on complex terrain.

How many WTs are in a test wind farm?

The test wind farm is equipped with a 108-m meteorological measurement mast and five rows of 2.5-MW WTs, each with a hub height of 80 m. The WTs are installed in a line with a uniform spacing of 3.8D . Fig. 4 shows the dimensions and direction of the wind farm.

How does weather affect wind-field measurements?

The duration of wind-field measurements is also affected by the weather conditions. Sometimes, researchers must wait for long periods for specific wind directions or wind speeds, which increases the cost of the experiment.
