Questions about inflow wind

Wind & Water Controls

Dear @Yarong.Zhou,

Here are my answers:

  1. The coordinates of up to 9 point where wind data may be output from InflowWind are specified by the user via inputs WindVxiList, WindVyiList, WindVziList.

  2. It is not common for a control system to be based on a tabulated look up of steady wind speed, which would not be measurable. For those control systems that do rely on wind speed, typically a wind speed estimator is used (based on rotor speed and pitch angle). A nacelle-mounted anemometer is often used as well as an input to a turbine control system.

  3. TurbSim can be used to develop full-field turbulent wind inflow data that be can used by InflowWind.

  4. I’m actually not too familiar with these InflowWind outputs, but my understanding is that they are tied to Lidar functionality built within the Simulink interface (documented a bit here: Linking measured wind data from LIDAR to Turbsim). Please note that a new and more powerful Lidar module is being developed and interface to OpenFAST to replace this feature.

Best regards,
