Samenvatting

In Brazil, the electric power system is operating close to its maximum capacity. Blackouts and electricity rationing recently occurred are evidence of this fact. Instead of building large power plants and long power lines, an alternative is to build a bigger number of small power plants located close to consumers. This type of plant can be built in rural areas or small villages and doesn’t need to be connected to the utility grid. This work presents study, modeling, simulation, and laboratory implementation of an induction generator-based system that is intended to use power available from small watercourses and rivers. An induction machine is used as a generator, and the control of the generated voltage amplitude is done automatically by supplying or absorbing reactive power to or from the induction machine, as needed. Reactive power is generated or absorbed by a static VAR compensator, actually a three-phase PWM inverter controlled by a Digital Signal Processor (DSP). Classic PI controllers and “fuzzy” logic-based controllers are implemented on the DSP program. Overall performance of the system operating with only PI controllers and with “fuzzy” logic-based controllers is compared. Laboratory results have shown that this system operating with “fuzzy” logic-based controllers can achieve a much better performance.
