Wind Farm Simulations Using a Full Rotor Model for Wind Turbines

摘要

Flow-field simulation of an entire wind farm is performed using a full rotor model for the wind turbines. The analysis scheme combines several technologies, viz. unstructured mesh solvers, dynamic overset gridding, high-order Cartesian discretizations, adaptive mesh refinement, meso-scale/micro-scale coupling and efficient flow visualization to enable high fidelity simulation of an entire wind plant. The Helios software framework, which is the product of the DoD CREATE A/V program is utilized to perform the simulations. Results are shown for a wind plant modeled with the same lay out as the Lillgrund wind farm. This manuscript focuses on demonstration of technology and verification of expected trends in the flow field. Comprehensive validation with measurements will be the focus of the future work.
