Resumen
The induction generator has characteristics making it interesting for alternative sources of energy, such as low cost, ruggedness, low maintenance, high availability and good dynamic behavior. So, it is very much applied in alternative energy systems, where low cost, low maintenance and easy availability are essential characteristics. Although this generator is very attractive, its operation presents problems related to a poor voltage regulation, load dependent variable frequency, and the need of large size self-excitation capacitors, for standalone induction generator systems. In order to minimize these problems, this study proposes a
sparse matrix converter associated to an induction generator as a way to regulate the generated voltage, fix the frequency and increase the system reliability. Moreover, it allows the reduction of the self-excitation capacitors by draining out of the generator, mostly
resistive current thus, reducing capacitor costs and of the whole system size. In this dissertation is presented some simulation and practical results of a sparse matrix converter connected to the induction generator prototype developed in CEEMA laboratories. These results confirm the here presented theory and validate this work.
