Resumo: |
The present work is devoted to the development of a methodology for attenuation of the electromagnetic conjugate oscillations using insertion of AC components added to DC components in the field excitation of the synchronous generator of outgoing poles submitted to non-sinusoidal voltage conditions. It is used mathematical modeling able to consider the effects of harmonic components of current and voltage and study is carried out on the oscillations of conjugate using computational simulations. The synchronous generator is connected to the bus and subjected to sinusoidal and non-sinusoidal voltage conditions with the insertion of linear and non-linear loads. It is verified that the conjugate oscillations are influenced by the insertion of nonlinear loads, inducing the periodic behavior, being the main components of the sixth order and their multiple. The results obtained reduce the oscillating electromagnetic torque components by approximately 50%. |
