Abstract

Present study proposes a load equivalent tower shadow modeling method for downwind turbines. It is expressed by bell shaped tower wake profile of BEM (Blade Element and Momentum Theory) on the bases of load equivalence with rotor-tower CFD (Computational Fluid Dynamics). It provides practical and useful models considering rotor-tower interaction and transient process while blades passing through the tower wake, which has been ignored in former models. The model was verified through field test of SUBARU80/2.0, 2MW downwind turbine. Furthermore, case studies of the turbine show the former modeling overestimates tower shadow effect.
