Comparative fatigue life assessment of wind turbine blades operating with different regulation schemes
(2019)
A comparative evaluation of the fatigue damage occurring in the blades of small wind turbines, with different power regulation schemes, has been conducted for the first time. Three representative test cases were built, one ...
High Order Recurrent Neural Control for Wind Turbine with a Permanent Magnet Synchronous Generator
(Revista Computación y Sistemas; Vol. 14 No. 2, 2010-12-15)
Abstract. In this paper, an adaptive recurrent neural
control scheme is applied to a wind turbine with
permanent magnet synchronous generator. Due to the
variable behavior of wind currents, the angular speed of
the ...
Hydraulic and rotor-dynamic interaction for performance evaluation on a Francis turbine
(Springer-Verlag France, 2017-08-01)
This paper proposes a new methodology to evaluate the technical state of a Francis turbine installed in a hydroelectric plant by coupling computational fluid dynamics (CFD) and rotor-dynamic analysis. CFD simulations ...

LPV wind turbine control with anti-windup features covering the complete wind speed range
(Institute of Electrical and Electronics Engineers, 2014-03)
This paper addresses the control of a variable-speed variable-pitch wind turbine in the whole wind speed range. To this end, a linear parameter varying anti-windup (AW) controller is proposed as part of a control structure ...
A vortex lattice program for steady state aerodynamic analysis of wind turbine blade load.

This paper presents a revised MATLAB program for estimating the subsonic
aerodynamic characteristics of an optimal design of wind turbine blades using the Vortex
Lattice Method (VLM). The aerodynamic characteristics of ...
Non-linear aeroelasticity: An approach to compute the response of three-blade large-scale horizontal-axis wind turbines
(Pergamon-Elsevier Science Ltd., 2014-06)
In this work, we present an aeroelastic model intended for three-blade large-scale horizontal-axis wind turbines. This model results from the coupling of an existing aerodynamic model and a structural model based on a ...
