Reduced-order models of squirrel-cage induction generators for fixed-speed wind turbines under unbalanced grid conditions
Rolán Blanco, Alejandro; Córcoles López, Felipe; Bogarra Rodríguez, Santiago; Monjo Mur, Lluís; Pedra Durán, Joaquim (2016-06)
Article
Accés obertThis paper develops a study of reduced-order models for squirrel-cage induction generators used in the fixed-speed wind turbines. The squirrel-cage of these generators must be modeled with a double-cage for accuracy purposes. ... -
Simulation of wound rotor synchronous machine under voltage sags
Aguilar Galván, Daniel; Vázquez Guzmán, Gerardo; Rolán Blanco, Alejandro; Rocabert Delgado, Joan; Córcoles López, Felipe; Rodríguez Cortés, Pedro (IEEE Press. Institute of Electrical and Electronics Engineers, 2010)
Comunicació de congrés
Accés obertThis paper presents a study of the Wound Rotor Synchronous Machine (SM) stability under voltage sags (dips). Machine behavior has been analyzed by considering different magnitudes (or depths) and duration of the sag. ... -
Small synchronous machine protection during voltage sags caused by MV grid faults
Bogarra Rodríguez, Santiago; Rubion, X.; Rolán Blanco, Alejandro; Córcoles López, Felipe; Pedra Durán, Joaquim; Iglesias, J. (2018-03-01)
Article
Accés obertThis paper analyses the impact of symmetrical and unsymmetrical voltage sags caused by distribution and transmission faults on the dynamic behaviour of small salient-pole synchronous machines connected to the MV grid, and ... -
Symmetrical and unsymmetrical voltage sag effects on the three-phase synchronous machine stability
Aguilar Galván, Daniel; Rolán Blanco, Alejandro; Vázquez, Gerardo; Córcoles López, Felipe; Rodríguez Cortés, Pedro (2009)
Comunicació de congrés
Accés obertThis paper focuses on the effects of voltage sags, both symmetrical and unsymmetrical, on the three-phase Synchronous Machine (SM). Voltage sags on SM cause speed variations, current and torque peaks and hence may cause ... -

Testing of three-phase equipment under voltage sags
Rolán Blanco, Alejandro; Córcoles López, Felipe; Pedra Durán, Joaquim; Monjo Mur, Lluís; Bogarra Rodríguez, Santiago (2015-04-09)
Article
Accés obertThis paper provides insight into the testing of three-phase equipment exposed to voltage sags caused by faults. The voltage sag recovers at the fault-current zeros, leading to a ‘discrete’ voltage recovery, that is, the ... -
Voltage recovery influence on three-phase grid-connected inverters under voltage sags
Rolán Blanco, Alejandro; Giménez, Pablo; Yague, Sauro J.; Bogarra Rodríguez, Santiago; Saura Perisé, Jaime; Bakkar, Mostafa (2019-02-12)
Article
Accés obertFaults in power systems cause voltage sags, which, in turn, provoke large current peaks in grid-connected equipment. Then, a complete knowledge of the inverter behaviour is needed to meet fault ride-through capability. The ... -
Voltage sag influence on controlled three-phase grid-connected inverters according to the Spanish grid code
Bakkar, Mostafa; Bogarra Rodríguez, Santiago; Rolán Blanco, Alejandro; Córcoles López, Felipe; Saura Perisé, Jaime (2020-02-03)
Article
Accés obertTo ensure the safe operation of the grid, there are some requirements to be taken into consideration to connect power converters. During abnormal conditions – e.g. during voltage sags –, the control of the converters is a ...
