Previous issue date: 2010-06-28 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / This work describes the experimental implementation of a shunt active power filter applied to a three-phase induction generator. The control strategy of active filter turned to the excitation control of the machine and to decrease the harmonics in the generator
output current. Involved the implementation of a digital PWM switching, and was made a comparison of two techniques for obtaining the reference currents. The first technique is based on the synchronous dq reference method and the second on the theory of instantaneous power. The comparison is performed via simulation and experimental results. To obtain the experimental results, was mounted a bench trial and the control and communications needed were implemented using DSP - MS320F2812. The simulation results and experimental data proved the efficiency of the filter to apply, highlighting the technique of instantaneous power / Este trabalho descreve a implementa??o experimental de um filtro ativo paralelo de pot?ncia aplicado a um gerador de indu??o trif?sico. A estrat?gia de controle do filtro ativo voltou-se para o controle de excita??o da m?quina e para a minimiza??o dos harm?nicos na corrente de sa?da do gerador. Envolveu a implementa??o de um chaveamento PWM digital, tendo sido realizada a compara??o de duas t?cnicas para obten??o das correntes de refer?ncia. A primeira t?cnica se baseia no m?todo referencial s?ncrono dq e a segunda na teoria das pot?ncias instant?neas. A compara??o ? realizada via simula??o e resultados experimentais. Para obten??o dos resultados experimentais, foi montada uma bancada experimental e o controle e comunica??es necess?rias foram implementados utilizando-se um DSP - TMS320F2812. Os resultados de simula??o e experimentais obtidos comprovaram a efici?ncia do filtro para a aplica??o, com destaque para a t?cnica das pot?ncias instant?neas
