Resumo: This master’s thesis presents the development of a Self-excited Induction Generator (SEIG) and a Synchronous Generator (SG) based generation system, where the SG acts as reactive power compensator. In the generation system, the SEIG is kept supplying rated power, driven through a primary source of constant mechanical power. The SG, on the other hand, is driven by a constant speed primary source. A Electronic Load Controller (ELC) is used to consume the surplus active power generated by the SEIG that is not consumed by the consumer unit, in order to regulate system’s frequency. When the consumer’s load is greater than the SEIG’s rated power, SG provides active power to supply the demand, the ELC is turned off and frequency control is realized by SG’s speed controller. The microgrid reactive power is controlled by SG’s static excitation system, which is based on a Buck converter powered by an external DC source, acts to control the system’s voltage at common bus through adjusting the SG field voltage. The system elements are modeled in order to design excitation system and ELC controllers. The DSP based designed digital control system is applied in a generation systems test bench. A start-up method is developed, disregarding synchronism techniques. Simulation and experimental results are presented, validating the controllers design and the proposed system.
