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

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. 1.
