A comparison of techniques for fault detection in inverter-fed induction motors in transient regime

Fernandez-Cavero, Vanessa; Morinigo-Sotelo, Daniel; Duque-Perez, Oscar; Pons Llinares, Joan (Institute of Electrical and Electronics Engineers, 2017)

[EN] Fault detection in induction motors operating in non-stationary regimes has become a need in today's industry. Most of the works published deal with line-fed motors. Nevertheless, the number of inverterfed induction ...
Comparative study of speed estimators with highly noisymeasurement signals for Wind Energy Generation Systems

Carranza Castillo, Oscar; Figueres Amorós, Emilio; Garcerá Sanfeliú, Gabriel; González Morales, Luis Gerardo (Elsevier, 2011-03)

This paper presents a comparative study of several speed estimators to implement a sensorless speed control loop in Wind Energy Generation Systems driven by power factor correction three-phase boost rectifiers. This rectifier ...
DC Current Harmonics Reduction in Multi-Inverter Topology

Reyes, Eduardo; Sarasiri, Nuapett; Pena, Ruben; Riedemann, Javier; Andrade, Iván; Blasco-Giménez, Ramón; Jara, Werner (Institute of Electrical and Electronics Engineers, 2022-10)

[EN] This letter presents a Space Vector Pulse Width Modulation (SVPWM) strategy for reducing the DC-link current harmonics in a multi- Voltage Source Inverter (VSI) topology with common DC-link bus. The DC current harmonic ...
Fourier methods for the perturbed harmonic oscillator in linear and nonlinear Schrödinger equations

Bader, Philipp; Blanes Zamora, Sergio (American Physical Society, 2011)

[EN] We consider the numerical integration of the Gross-Pitaevskii equation with a potential trap given by a time-dependent harmonic potential or a small perturbation thereof. Splitting methods are frequently used with ...
Long-Term Operational Data Analysis of an In-Service Wind Turbine DFIG

Artigao, Estefania; Sapena-Bano, Angel; Honrubia-Escribano, Andrés; Martinez-Roman, Javier; Puche-Panadero, Rubén; Gómez-Lázaro, Emilio (Institute of Electrical and Electronics Engineers, 2019-01-29)

[EN] While wind turbine (WT) power capacities continue to increase and new offshore developments are being deployed, operation and maintenance (O&M) costs continue to rise, becoming the center of attention in the wind ...
Photonic millimeter-wave frequency multiplication based on cascaded four-wave mixing and polarization pulling

Vidal Rodriguez, Borja (Optical Society of America, 2012)

[EN] A technique for the frequency multiplication of microwave signals based on the combination of two optical nonlinear phenomena in a single nonlinear fiber is investigated. Multiple four-wave mixing is used to generate ...
Reliable Detection of Rotor Bars Breakage in Induction Motors via MUSIC and ZSC Methods

Morinigo-Sotelo, Daniel; Romero-Troncoso, R.D.; Panagiotou, P.A.; Antonino-Daviu, J.A.; Gyftakis, Konstantinos N. (Institute of Electrical and Electronics Engineers, 2018-03)

[EN] Induction motors are used in a variety of industrial applications where frequent startup cycles are required. In those cases, it is necessary to apply sophisticated signal processing analysis methods in order to ...
Transient tracking of low and high-order eccentricity-related components in induction motors via TFD tools

Climente Alarcón, Vicente; Antonino-Daviu, J.; Riera-Guasp, Martín; Pons Llinares, Joan; Roger-Folch, José; Jover-Rodriguez, P.; Arkkio, A. (Elsevier, 2011)

[EN] The present work is focused on the diagnosis of mixed eccentricity faults in induction motors via the study of currents demanded by the machine. Unlike traditional methods, based on the analysis of stationary currents ...
