Title

Below-rated control of swept-blade wind turbines

Lead Author Affiliation

Mechanical Engineering

Introduction

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.
