Aerodynamic Optimization Design and Calculation of a 2MW Horizontal Axial Wind Turbine Rotor Based on Blade Theory and Particle Swarm Optimization

The aerodynamic optimization design and calculation of a 2MW horizontal axial wind turbine (HAWT) rotor are carried out based on particle swarm optimization (PSO) and the HAWT blade theory, which adopts wind velocity correction produced by the complicated wake vortexes and alterable circulation along the wind rotor blade axis, and combines the aerodynamic features of a horizontal axial wind turbine to evaluate its aerodynamic performance. A computational optimization design example indicates that the optimization design method, put forward in the paper, has good feasibility and reliability in aerodynamic optimization design and computation of a HAWT rotor.
