Improvement of low frequency identification for wind turbines employing eemd and time integration.
(Universidad Nacional de Colombia Sede Manizales, 2014-12-20)
Nowadays wind turbines are wide employed as a clean energy resource. However, their use implies a wide number of eolic structures which also requires a demanding monitoring and maintenance. The most technique employed for ...
Rebobinadora elétrica com ajuste de velocidade e contagem do número de voltas
(Universidade Tecnológica Federal do ParanáMedianeiraBrasilTecnologia em Manutenção IndustrialUTFPR, 2015-06-15)
One of the greatest difficulties found in rewinding electric motors is the expertise of professionals that know such a procedure. Rewinding is widely used because it leads to low maintenance costs and because it is not ...
An Electrical Approach to Mechanical Effort Reduction in Wind Energy Conversion Systems
(Institute of Electrical and Electronics Engineers, 2008-12-02)
A strategy for controlling wind farms composed of variable-speed machines is considered in this paper. It is shown that mechanical efforts produced by wind gusts on individual machines can be reduced by means of a supplementary ...

Desarrollo de una bobinadora concéntrica semi automática para la reparación de motores eléctricos de baja tensión para la empresa SIEM
(2022-09)
The error rate in the repair of low voltage electric motors by technicians is high due to the fact that technicians lack the necessary conditions to supervise the number of turns, distance and adjustment that occurs in a ...
Otimização estrutural de pás de turbinas eólicas de material compósito via funções de base radial
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2021-02-26)
Wind turbines are machines capable of transforming wind kinetic energy into electricity. The turbine blades are responsible for converting aerodynamic forces into torque for the generator. In most cases, blades are made ...
A PLL-based resampling technique for vibration analysis in variable-speed wind turbines with PMSG: A bearing fault case
(Academic Press Ltd - Elsevier Science Ltd, 2017-02)
Condition monitoring in permanent magnet synchronous machines has gained interest due to the increasing use in applications such as electric traction and power generation. Particularly in wind power generation, non-invasive ...
Design of a decoupling strategy and parameter calculation for six-phase PM machines with general angular displacement
(SAGE Publications, 2017-11)
A novel decoupling model for a six-phase permanent magnet machine is proposed in this paper. The model considers the machine as two independent three-phase stator windings that are spatially shifted by a generic angle ...
