Below-rated control of swept-blade wind turbines

Introduction/Abstract

Modelling studies have shown that 1.5 and 3.0 MW wind turbines with blade sweep have an increased annual energy production (AEP) of approximately 5% when compared to straight-blade wind turbines. Swept-blades are designed to twist under loading. As the blade twists, aerodynamic forces are lowered and therefore reduce the damage done to the blade over time. This allows the swept-blade rotor diameter to be increased to capture more power.
