The scope of this project is to provide a basic open-source open-access controller that can be used by the community as a reference.
The basic DTU Wind Energy controller is designed for pitch-regulated variable speed wind turbines. The controller features both partial and full load operation capabilities as well as switching mechanisms ensuring smooth transition between the two modes of operation. The partial load controller is based on a classical K Omega**2 strategy or on a proportional-integral controller to track constant tip speed ratio. The full load controllers is also based on classical proportional-integral control theory. The controller also includes drivetrain and tower dampers, a rotor speed exclusion zone, and filters on the feedback signal.
Blade pitch servo and generator models are not included in this controller. They can be found in the project ServoAndUtilities.
The repository includes Visual Studio project (for Windows) and Makefiles (for Linux) to create DLLs to interface the controller to HAWC2 and Bladed.
The controller is written in Fortran and it is compatible with Intel and GFortran compilers. It can be compiled both on Windows and Linux.
-
For compilation in Windows (as a dll), use the Visual Studio Solution or Project files provided (*.sln, *.vfproj)
-
For compilation in Unix (as a so file), go to the /src subfolder and type
make FC=compiler. Where 'compiler' should be replaced by an already installed compiler (e.g. ifort, mpif90).
The documentation can be found here.
The documentation is written in Sphinx and can be built by typing:
$ cd docs
$ make html
The documentations requires the Fortran Sphynx extension that can be pip installed by typing:
$ pip install sphinx-fortran
