Experimental Analysis of Harmonic Distortion in Isolated Induction Generators

The use of induction generator, replacing the continuous and synchronous generators, has proved to be an interesting solution for the supply of electricity in remote areas where the supply through a distribution network is not economically viable. In some cases the use of this machine type is appropriate in these areas, with the same associated with non-conventional systems of electricity, such as wind and hydro generation small. In these isolated systems is common to use cage induction generators with excitation capacitors, known as self excited induction generators. Allied to this, there has been an increase in the number of non-linear loads, at all levels of electricity consumption. Thus, it becomes necessary to study experimentally the harmonic distortion of voltage and current in this type of generator, which can supply non-linear loads that may be present in these remote areas.
