Investigation of various Application Flatness Techniques in a Single Machine Infinit Bus System (SMIBS)

چکیده مقاله

This  paper  focuses  attention  on  the  concept  of  flatness-based  feedback  linearization  and  its practical application to the design of an optimal transient controller for a synchronous  machine.  The  feedback  linearization  scheme  of  interest requires the generation of a flat output from which the  feedback   control   law   can   easily   be   designed.Thus   the computation  of  the  flat  output  for  reduced  order  model  of  thesynchronous machine with simplified turbine dynamics is hereby presented. The corresponding linearized compensator is derived as well as the nonlinear controller for transient stabilization of a synchronous   machine subjected  to  large   disturbances.  The transient  behavior  of  a  single  machine  equipped  with  the  so designed   nonlinear   controllers  feeding   an   infinite  bus   is illustrated  via  simulation  in  Matlab  environment.  The  results obtained   for   transient   disturbances on  the  single  machine infinite  bus  system  (SMIBS)  are  presented  and  compared  with other  control algorithms to demonstrate the effectiveness of the proposed scheme.
