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.

Impact of Green Power Distributed Generation to Voltage Profile and Protection Issues by Different Penetration Levels - A Study Developed on ATP Draw

“…It is observed that the state of São Paulo has the greatest potential to generate surpluses, 2.244,33MW, which shows clearly and prominently raising the number of drive synchronous generators to be connected directly to the electrical distribution systems [7]. It is noteworthy that there is no consensus, meaning clear regulations as to the best mode of operation of the DG when connected to the power distribution system -PDS, nor wellestablished criteria of protection, connection, product quality and dynamic for a safe and effective connection [8] - [9]. Thus, this article aims to evaluate the main impacts arising from the installation of medium-sized synchronous generators in the operation of distribution networks.…”
