To optimize the yaw misalignment correction factor in your wake model for the Siemens Gamesa SWT-3.6-130 wind turbine, follow this structured approach:

  1. Data Collection:

    • Turbine Specifications: Obtain the SWT-3.6-130's technical data, including rotor diameter, blade length, and hub height.
    • Site Data: Collect topographical maps, roughness length, wind speed, direction, and if possible, LiDAR data for detailed wind flow information.

  2. Wake Modeling:

    • Select an appropriate wake model (e.g., Gauss or Curl) that can handle complex flows and yaw misalignment.
    • Adjust the model parameters based on the turbine's rotor-blade geometry and hub height.

  3. Terrain Consideration:

    • Use a CFD model or an advanced wake model to account for the site's complex terrain, incorporating varying elevations and surface roughness.

  4. Validation:

    • Compare model predictions with SCADA data to assess performance under different yaw conditions.
    • Conduct wind tunnel tests for empirical wake behavior data, if feasible.

  5. Sensitivity Analysis:

    • Evaluate the correction factor's sensitivity to variables like wind speed, direction, and yaw angle to refine adjustments.

  6. Iterative Refinement:

    • Adjust the correction factor iteratively, validating each modification against real data to enhance accuracy.

  7. Implementation and Monitoring:

    • Integrate the optimized correction factor into the wake model.
    • Continuously monitor and update the model with new data to maintain accuracy and adapt to site changes.

By systematically addressing each component, you can enhance the wake model's accuracy, ensuring optimal performance under varying conditions.
