Desenvolvimento de um regulador automático de tensão e de um estabilizador de sistema de potência utilizando lógica difusa

Abstract

A fundamental procedure to guarantee the energy quality in electric systems is the tension regulation. However, it is not a trivial activity due to the great number of state variations that an electric system is submitted. The effective compensation of eventual disturbances is crucial to guarantee the correct operation of an electric power system.

In the sense of improving this fundamental process exist some strategies that use regulators and conventional stabilizers, and other that use techniques more elabo rated.

Due the non-linear characteristics of electric systems, not always conventional controllers have satisfactory behaviors in conditions of real operation in power sys tems.

This work will use Fuzzy Logic to implement an automatic regulator of tension and a power system stabilizer for electric generators, aiming to improve the generation processes in electric systems.

Results obtained through computational simulations and of real experiments indi cated an improvement regarding the utilization of conventional system
