Study of the state a Francis turbine
(Politechnika Gdanska, Wydzial Oceanotechniki i Okretownictwa, 2013-04-01)
This paper presents a methodology to evaluate the technical state of a Francis turbine by shaft rotor dynamic simulation. There are several rotor dynamic criteria that define the technical state of a turbo-machine. To feed ...
Active Disturbance Rejection Control of Horizontal-Axis Wind Turbines
(2017-03-22)
Abstract. Wind turbines are complex nonlinear machines whose main objective is to convert the wind energy into electric power. These systems work in two main operating regions. In region 2, the energy captured must be ...
An Integrated Procedure for the Structural Design of a Composite Rotor-Hydrofoil of a Water Current Turbine (WCT)
(Springer, 2013-06-25)
This paper shows an integrated structural design optimization of a composite rotor-hydrofoil of a water current turbine by means the finite elements method (FEM), using a Serial/Parallel mixing theory coupled with a ...
Study of the control structure of a small wind turbine with permanent magnet synchronous generator
(2012-12-12)
This paper presents the analysis of the two control structures used in wind generation systems with permanent magnet synchronous generators, variable speed and fixed pitch, to determine which structure is most appropriate ...
Modeling and robust control of a twin wind turbines structure
(Pergamon-Elsevier Science Ltd, 2017-12)
The control of a new structure of twin wind turbines (TWT) is presented in this paper. This new concept includes two identical wind turbines ridden on the same tower, which can pivot face the wind with no additional actuator. ...
A composite beam finite element for multibody dynamics: Application to large wind turbine modeling
(Elsevier, 2013-11)
This work presents a beam finite element with multibody capabilities for modeling high aspect ratio composite wind turbine components, particularly the tower and the blades. The proposed formulation is based on an Updated ...
