Voltage source inverter for voltage and frequency control of a stand-alone self-excited induction generator

grantor: University of TorontoThis thesis investigates the application of a Voltage Source Inverter based controller for the regulation of voltage and frequency of a stand-alone self-excited induction generator. The steady state and dynamic system equations are formulated and the system behavior is studied. Based on the model, the design of the VSI-based controller is obtained. The design and rating of the controller with different DC side configurations is derived for the system model. An experimental generator system with the proposed controller has been built. In order to verify theoretical results and the technical feasibility of the VSI-based controller, various tests are conducted. The test results demonstrate the excellent performance of the proposed concept.M.A.Sc
