Rotor Aerodynamic Detection

When Rotor aerodynamic imbalance impacts your wind turbine performance... Windfit is there to help. How?

Let us share a client's case where Windfit detected a sudden increase of the aerodynamic imbalance (1). At the same time, a significant plunge of the turbines power curve was observed (2) on the Windfit web portal results.
