Analysis of the Influences of Changes in Gains and Time Constants in a Power Factor Regulator Using ATP-EMTP

Abstract

The   objective   of   this   study   is   to   analyze   the influence  of  the  gains  and  time  constants  in  a  control  system  of  a Power  Factor  Regulator.  This  regulator  was  modeled  using  the “TACS –Transients  Analysis  Control  System”  routine  "ATP-EMTP   -   Alternative   Transients   Program".   This   regulator   is connected  to  a  synchronous  machine  of  an  independent  producer, and later, is observed the behavior of machine speed in steady state, the rms  voltage  and  power  factor  is  observed  in  the PCC  (Point of Common Coupling) of the system. Finally, appropriate conclusions about the influence of the gains and time constants for the regulator power  factor is  conducted,  seeking  a  system  that  behaves as  stable as  possible,  taking  into  account  the  rules  related  to  the  insertion of distributed generators in the Electric System.
