| Abstract | |
This thesis proposes a novel solution to connect a three-phase induction generator directly to a single-phase feeder. Typical situations are found in rural areas in which is possible to obtain local power generation. High power quality at the customers such as sinusoidal and balanced voltages, constant frequency and regulated AC voltage, is provided. Additionally, unity power factor on the feeder is obtained. A three-phase shunt voltage source inverter VSI-PWM is connected at the point of common coupling. This converter processes a fraction of the load power that is associated with unbalances, reactive power and harmonics, as well. The efficiency of the partial power processing is higher when compared to double-conversion systems. On the other hand, the system is able to manage a DC source as a fuel cells, a solar panel and batteries. If only the single-phase source is available, the system operates as a single to three-phase line-interactive converter (AU) | |
