Structural Optimization of a Direct-Drive Wind Turbine Generator Inspired by Additive Manufacturing
Autor: Lee Fingersh, Austin C. Hayes, Katherine Dykes, Latha Sethuraman
Publikováno v: Procedia Manufacturing. 26:740-752
This study explores the structural freedom and design opportunities of additive manufacturing for a 5-MW direct-drive generator for a wind turbine and compares it to more traditional spoke-arm designs using NREL’s GeneratorSE. The work focuses on l

Additive Manufacturing: A New Paradigm for the Next Generation of High-Power-Density Direct-Drive Electric Generators
Autor: Katherine Dykes, Latha Sethuraman, Austin C. Hayes, Lee Fingersh
Publikováno v: Volume 2: Heat Exchanger Technologies; Plant Performance; Thermal Hydraulics and Computational Fluid Dynamics; Water Management for Power Systems; Student Competition.
In recent years, there has been a growing demand for high-power-density direct-drive generators in the wind industry owing to their high reliability, torque per unit volume, and conversion efficiencies. However, direct-drive wind turbine generators a

Control of variable-speed wind turbines: standard and adaptive techniques for maximizing energy capture
Autor: Lucy Y. Pao, Kathryn Johnson, Mark J. Balas, Lee Fingersh
Publikováno v: IEEE Control Systems. 26:70-81
This article considers an adaptive control scheme previously developed for region 2 control of a variable speed wind turbine. In this paper, the question of theoretical stability of the torque controller is addressed, showing that the rotor speed is

Methods for Increasing Region 2 Power Capture on a Variable-Speed Wind Turbine
Autor: Mark J. Balas, Lucy Y. Pao, Lee Fingersh, Kathryn Johnson
Publikováno v: Journal of Solar Energy Engineering. 126:1092-1100
The standard region 2 control scheme for a variable-speed wind turbine,t c5Kv 2 , has several shortcomings that can result in significant power loss. The first of these is that there is no accurate way to determine the gain K; modeling programs are n

Field Testing LIDAR-Based Feed-Forward Controls on the NREL Controls Advanced Research Turbine
Autor: Alan Wright, Fred Belen, Lee Fingersh, Andrew Scholbrock, Paul Fleming, David Schlipf, Florian Haizmann
Publikováno v: Scopus-Elsevier
Wind turbines are complex, nonlinear, dynamic systems driven by aerodynamic, gravitational, centrifugal, and gyroscopic forces. The aerodynamics of wind turbines are nonlinear, unsteady, and complex. Turbine rotors are subjected to a chaotic three-di
