Comparison of current control for low harmonic distortion applied to a small wind generation system with permanent magnet synchronous generator
(2012-12-12)
This paper presents a comparison between of two type of current control to reduce the THDi and increase the PF in a Three-Phase Boost Rectifier driving a small wind turbine. The two
types of current controls are peak ...
Improved Mechanical Properties of Aluminium Powder-Carbon Nanotubes and Epoxy Nanocomposites to Fabricate Blades for Wind Turbines and Different Components of Machines and Equipment
(Universidad de San Carlos de Guatemala, 2015)
A large deformation small strain formulation for the mechanics of geometrically exact thin-walled composite beams
(Elsevier, 2014-11)
This work presents a new formulation of the geometrically exact thin walled composite beam theory. The formulation assumes that the beam can undergo arbitrary kinematical changes while the strains remain small, thus ...
Numerical simulation of the flow around a straight blade darrieus water turbine
(EnergiesSuiza, 2020-03-03)
In this study, three-dimensional transient numerical simulations of the flow around a cross flow water turbine of the type H-Darrieus are performed. The hydrodynamic characteristics and performance of the turbine are ...
Numerical study of the effect of winglets on the performance of a straight blade darrieus water turbine
(MDPI, 2018-01-28)
This study deals with the three-dimensional unsteady numerical simulation of the flow around a cross-flow vertical-axis water turbine (CFWT) of the Darrieus type. The influence of turbine design on its hydrodynamic ...
Estudo comparativo de pás para aerogeradores de grande porte fabricadas em materiais compósitos reforçadas com fibra de carbono ou fibra de vidro
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisProcessamento de Materiais a partir do Pó; Polímeros e Compósitos; Processamento de Materiais a part, 2013-12-30)
The research and development of wind turbine blades are essential to keep pace with worldwide growth in the renewable energy sector. Although currently blades are typically produced using glass fiber reinforced composite ...
A COMPARATIVE STUDY OF MPPT STRATEGIES AND A NOVEL SINGLE-PHASE INTEGRATED BUCK-BOOST INVERTER FOR SMALL WIND ENERGY CONVERSION SYSTEMS
(Ieee, 2011-01-01)
This paper presents the analysis of some usual MPPT (Maximum Power Point Tracking) strategies intended for small wind energy conversion (up to 1kW) based on permanent magnet synchronous generators (PMSG), considering the ...
Screening analysis and unconstrained optimization of a small-scale vertical-axis wind turbine
(Universidade Estadual Paulista (Unesp), 2021-06-30)
The demand for alternative and renewable energy sources has been growing substantially in recent years due, among other things, to the economic and environmental aspects of conventional sources, such as oil and its ...
