Abstract

This  research  work  is  devoted  to  the  criticalevaluation  of  the  role  of  the  dc-bus  in  the  behavior  of  three-phase  adjustable-speed  drives  with  voltage  sags.  In  particular,the  dc-link  voltage  variation  under  voltage  sag  and  its  depen-dence  on  bus  capacity,  dc-link  resistance  and  inductance  andsource impedance.The analysis can be used to introduce additional capacitancein the dc-link in order to increase the ride-through capability ofthe ASD.Both an electromagnetic transient model and a set-up facilityhave  been  introduced.  This  test  platform  can  be  used  in  orderto study the sensitivity of ASD to different disturbances.
