VANE

VANE (Visualization and Automated Natural-frequency Extraction) is an open-source (Apache-2.0) Python tool for the linearization analysis of wind turbines in OpenFAST. It takes an OpenFAST model and the turbine’s operating curve to labelled Campbell diagrams and modal results:

  1. automatic set-up of the linearization case of every operating point, with pre-flight checks of the deck (The OpenFAST linearization sweep);

  2. the sweep, run in parallel, with automatic trim retries and settle runs for floating turbines (Verifying the trimmed operating point);

  3. the MBC3 transform and the azimuth average on the delivered azimuths (Mode identification);

  4. automatic mode identification, labelling and tracking across operating points;

  5. Campbell diagrams with excitation lines, resonance crossings, and tabular and Excel summaries (Campbell diagrams);

  6. mode-shape visualization, static, 3-D and VTK (Visualization);

  7. Floquet analysis and per-branch averaging-error estimates (Azimuth averaging); and

  8. state-space and LPV export for estimator and controller design (State-space export).

VANE handles fixed-bottom and floating turbines. It is developed at the Marine Structural Mechanics and Integrity Lab (SMI Lab), Inha University.

The current stable release is 0.1.1. The public API is documented in the API reference and is stable. VANE follows semantic versioning: a breaking change to the documented public API is made only with a new major version and is recorded in the Changelog.
