I’ve been trying to reproduce the power curve and the data shown in Figure 9-1 of the 2009 report of the NREL 5MW Reference Wind Turbine. I’ve run simulations for the onshore model at different steady and homogeneus (null shear exponent) wind speeds. Results look fine, yet the rated wind speed that I’m obtaining is 11.8 m/s, instead of the 11.4 m/s stated in the report.
Results are attached to the post; the original data points are taken from viewtopic.php?t=363.
My guess is that the difference is simply due to the development that fast and the various submodules (or the controller itself) went through all these years: is it plausible? Are there some particular parameters that I should double-check?
Also, is there maybe any more up-to-date data available?
