  1. Hi Igarcia The mast must be covered with a WAsP CFD tile to calculate the generalized wind climate Kind regards, Andreas
  2. Hi Lucas, Suppose the obstacle group is associated with the met station, then obstacle effects are only accounted for in the generalized wind climate. You need to move the obstacle group to the project level if everything, including the resource grid, should include obstacle effects Kind regards Andreas
  3. Hi, The 1,000,000 point limit was removed with WAsP 11. See the release notes here: https://www.wasp.dk/Download/WAsP12-Suite-Installer/WAsP11_ReleaseNotes. If you use WAsP 11 or 12, then you are safe Kind regards Andreas
  4. Hi Pedro, If you have a GWC, then you can use your WAsP cross-prediction script, irrespectively if the GWC stems from measurement or mesoscale simulations. The hard part is to generate the GWC from mesoscale simulations. Generalisation depends not only on your mesoscale map but also on your mesoscale simulation parameters. When making a wind atlas from mesoscale-simulations, we generally try many different setups of the mesoscale model and validate each against measurements before we decide on which configuration we will use for production runs. Therefore, it is not trivial to generate the GW
  5. Hi. We are working on it, but I am afraid that it is not currently possible.
  6. Thanks, Gaoithe, There have been some problems with the SRTM download; when this happens, you can also download from the GWA Map Warehouse inside the Map Editor. I think it worked without problems Kind regards Andreas
  7. Hi Karvel, I haven't used your method of reducing the hub height of the turbines before. That said, there is no fundamental difference between using the CFD or IBZ model, you can, therefore, apply the same method to the WAsP CFD model. You need to be sure that you are using CFD-results at both the mast and turbine positions. As long as you don't mix IBZ and CFD in the same project, you should be fine. kind regards Andreas
  8. Hi Jose, You can indeed use WAsP alone. When you buy a WAsP licence, you get access to WAsP, WAsP Engineering and WAT - these can be downloaded from the wasp web-page. With WindPRO you buy the modules you need. The module MODEL is the interface between WAsP and Windpro, so you need to purchase both a WAsP license and MODEL to do resource calculations in WindPRO. You can buy WAsP licences from both DTU and EMD. If you give EMD a call, they can better describe the different modules of WindPRO. kind regards Andreas
  9. One option is to use WAsP 12 where you can select two different density correction policies in the WTG hierarchy member - that will automatically be adopted across all turbine sites. The default policy is to use interpolation as described in IEC standard 61400-12-1. The other option is to use Svenningsen extrapolation method (adjusted IEC extrapolation method, improved to match turbine control) described in the abstract/poster “Proposal of an Improved Power Curve Correction”, presented by Lasse Svenningsen (EMD International A/S) at the European Wind Energy Conference & Exhibition 2010 in Wars
  10. It is difficult to get reliable power curves for small turbines. We made the webpage mywindturbine.com dedicated to small turbine - please check if it has the power curves you are looking for
