Steady-state and transient performance of HVDC link based 3-level VSC supplying a passive load / Mohamed Abdel Djalil Djehaf in Revue des sciences et de la technologie, N° 31 ([01/10/2015])

Public ISBD [article]  in Revue des sciences et de la technologie > N° 31 [01/10/2015] . - p. 80 Titre : Steady-state and transient performance of HVDC link based 3-level VSC supplying a passive load Type de document : texte imprimé Auteurs : Mohamed Abdel Djalil Djehaf, Auteur ; Sid Ahmed Zidi, Auteur ; Samir Khadjeri, Auteur Année de publication : 2015 Article en page(s) : p. 80 Langues : Français Mots-clés : HVDC- voltage source converter (VSC) - IGBT- SPWM- Control design - passive load Résumé : This paper investigates the steady-state and transient performance of high-voltage DC (HVDC) transmission systems connected to passive network. The VSC HVDC tie employing PWM may well represent the ultimate FACTS device. Besides controlling the through power flow, it can supply reactive power and provide independent dynamic control at its two terminals. The control systems for rectifier and inverter are discussed in DC (HVDC) transmission systems based on three-level voltage source converters. The study involves analysis of active-reactive power capabilities (P-Q envelope) including active power flow and provision of voltage support to AC networks. The transient performance is explored by examining the VSC HVDC response to external AC faults. Finally, the models and results are presented and tested by simulations using Matlab Simulink and itsSimPowerSystems toolbox.
