Presentation Transcript

  1. Aeroservoelastic Modelling and Active Load Alleviation of Large Wind Turbine Blades Bing Feng, Ng Rafael Palacios, Eric C. Kerrigan, J. Michael R. Graham Imperial College London UKACC PhD Presentation Showcase

  2. Introduction • Turbines - larger, higher loadings. • Require active control surfaces – flaps. UKACC PhD Presentation Showcase

  3. Modelling • SHARP (Simulation of High Aspect Ratio Planes) • Geometrically Non-linear Composite Beam • Unsteady Vortex Lattice Method UKACC PhD Presentation Showcase

  4. Results • Flap 20% span, 10% local chord mean position of 80% span. • Single rotating blade. LQG controllers (Gaussian) • Flap defl. Angle ≤ ±10°, Flap defl. Rates ≤ ±100°/s UKACC PhD Presentation Showcase

  5. Conclusions and Future work • Putting together a composite beam and UVLM directly in a linear state-space form for ROM and controls. • Showed load alleviation using LQG controller with flaps to achieve on average 20-25% reduction in RBM, tip defl, DEL. • Further work into load alleviation with inclusion of tower dynamics. • Appreciation to Singapore Energy Innovation Programme Office for funding support. • Special thanks to Dr. Henrik Hesse for his contribution to the structural modeling.
