Load reduction for two-bladed horizontal-axis tidal current turbines based on individual pitch control

Ocean Engineering, 2020
Abstract With the large progress in tidal current energy, the size of tidal current turbine (TCT) rotors has increased, leading to more substantial asymmetrical loads. In this study, severe asymmetrical loads were investigated by a sea trial experiment with a 600-kW two-bladed horizontal-axis TCT.

Flap-wise loads reduction of rotor blades by embedded flap-wise absorbers

The Aeronautical Journal, 2016
ABSTRACTElastomeric and Fluidlastic®absorbers are proposed to be embedded in blade cavity to reduce troublesome second harmonic flap-wise blade loads of rigid rotors. A simple model of a blade with a flap-wise dynamic absorber is derived to investigate centrifugal force effects on the absorber's rotating frequency.

Individual Pitch Control of A Clipper Wind Turbine for Blade In-plane Load Reduction

2018 Annual American Control Conference (ACC), 2018
This paper proposes an $H_{\infty}$ individual pitch controller for the Clipper C96 2.5 MW wind turbine installed at University of Minnesota. Different with existing results aimed to mitigate the blade out-of-plane loads, the proposed controller focuses more on reducing the blade in-plane loads. This is because the in-plane loads are dominating parts
