Influence of tower shadow and wind turbulence on the performance of power system stabilizers for DFIG-based wind farms / Hughes, F.M. in IEEE transactions on energy conversion, Vol. 23 n°2 (Juin 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°2 (Juin 2008) . - pp. 519 - 528 Titre : Influence of tower shadow and wind turbulence on the performance of power system stabilizers for DFIG-based wind farms Type de document : texte imprimé Auteurs : Hughes, F.M., Auteur ; Anaya-Lara, O., Auteur ; Ramtharan, G., Auteur Année de publication : 2008 Article en page(s) : pp. 519 - 528 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Aerodynamics;  asynchronous  generators;  poles  and  towers;  power  system  simulation;  power  system  stability;  turbulence;  wind  power  plants Résumé : The aim of the paper is to demonstrate the way in which mechanical power variations, due to tower shadow and wind turbulence, influence control performance of power system stabilizer (PSS) loops for doubly-fed induction generators (DFIGs). The PSS auxiliary loops are applied on a specific DFIG control scheme, the flux magnitude and angle controller (FMAC). However, since the PSS signal is applied at the output of the basic controller, the PSS performance characteristics displayed are deemed typical for DFIG control schemes in general. The relative capabilities of PSS controllers based on stator power, rotor speed, and network frequency, when the DFIG turbine is subjected to aerodynamic torque variations, are investigated via simulation studies. A two-generator aggregate model of a wind farm is introduced, which enables the influence of tower shadow and wind turbulence on both an individual turbine and on the overall wind farm itself to be assessed.
