Abstract: Electricity suppliers today are increasingly focused on delivering high-quality power to customers. With advancements in power electronics, various solutions have been developed to counteract fluctuations in distribution networks, aiming to provide the best possible power quality. This thesis examines the use of a three-phase self-excited induction generator (SEIG) with a static compensator (STATCOM) for voltage regulation. The current-controlled voltage source inverter (CC-VSI) functions as the STATCOM, providing a rapid dynamic response to stabilize the SEIG terminal voltage during significant load changes, acting as both a source and sink of reactive power. To model the SEIG-STATCOM system feeding unbalanced loads, performance equations are derived using stationary reference frame d-q variables. A transient analysis is conducted to evaluate the voltage build-up, STATCOM switching, and the impact of applying and removing balanced or unbalanced resistive/reactive loads. The STATCOM maintains SEIG terminal voltage through reactive power compensation and reduces harmonics introduced by consumer loads. A control algorithm based on single-phase synchronous D-Q frame theory is used to generate gating pulses for the three-phase STATCOM, implemented using MATLAB/SIMULINK software.
