HAWC2 Models

Collection of pip-installable hawc2 models.

Installation

pip install hawc2models

Example

from hawc2models import IEA22MW, DTU10MW

# IEA 22MW Reference turbine
htc = IEA22MW(folder='IEA-22-280-RWT')

# specific version
htc = IEA22MW(folder='IEA-22-280-RWT_v1.0.1', version='refs/tags/v1.0.1')

# DTU10MW Reference wind turbine
htc = DTU10MW(folder='DTU10MW')

Background

Current status

We have reference models in different locations, e.g:

https://www.hawc2.dk/models https://gitlab.windenergy.dtu.dk/rwts/dtu-10mw-rwt (frza’s model source) https://gitlab.windenergy.dtu.dk/hawc-reference-models (rink’s group with models (e.g. a copy of dtu10mw) and utils) https://github.com/IEAWindSystems (IEA3.4, 10, 15, 22)

Moreover, we have copies of the dtu10mw in the test_files folder of wetb, pytest_hawc2, hawc2lib, etc.

The models have very different sets of sensors. IEA22MW, for instance, has ~2000 aerodynamic sensors, which is just slowing down simulations for most users.

dtu10mw.py (https://gitlab.windenergy.dtu.dk/HAWC2/pytest_hawc2/-/blob/master/test_files/DTU10MW/dtu10mw.py?ref_type=heads) contains functionality to

• Set tilt, cone, yaw
• Set fixed pitch and rotor speed
• Make blades stiff
• Make blades straight
• Set aero methods: aero_calc, induction, tiploss, dynstall
• Set wind: wsp, tint, turb_format, shear
• Set gravity

https://gitlab.windenergy.dtu.dk/hawc-reference-models has functionality to:

• Clone hawc2binary
• Clone/download dlls
  • https://gitlab.windenergy.dtu.dk/OpenLAC/control-binary/control-win32.git
  • towerclearance_mblade.dll from artifact
  • nrel-5mw-discon from artifact
• base_to_hs2
• base_to_step
• base_to_turb
• base_to_test

Vision

• From roadmap
  • Reference model with full IEC 61400 DLB data set + post-processing
  • Example-model-library (exercises/walk-throughs)
  • Comparisons with measurements
• From users’ perspective:
  • One place to find all (up-to-date) HAWC2 reference models or links to source repositories?
  • Model similarity? (same kind of output, wind, aerodynamic, tiploss, tower shadow, turbulence, controllers?)
  • Newest controllers?
  • Including hs2 section
  • Step and turb?
  • Picture of model
  • DLB Reference loads?
  • Our and/or users comments/issues regarding the models? e.g.  DTU10MW has aerodynamic discontinuties along blade due to change of profiles  IEA22MW uses 100 aerodynamic calculation points because…”
• From test framework perspective
  • Pip installable
  • Download models from source repositories. Consistent or newest version?
  • Update dll’s?
  • Features as in dtu10mw.py. For all or just a subset?
• Other considerations
  • Should we try to change/fix the source repositories (e.g. reduce the number of sensors of the IEA22MW) or just provide a website with “our” versions?

Open questions

• Where should model source files be stored
• How to obtain/download control dlls
• How to handle updates of control dlls and models
• What is a standard model (wsp, turbulence, controller/fixed)
• Which standard sensors should exist
