STATCOM-Based Controller for a Three-Phase SEIG Feeding Single-Phase Loads Abstract This dissertation presents single-phase power generation using a three-phase self-excited induction generator (SEIG) working in concurrence with a three-phase static synchronous compensator(STATCOM).The STATCOM is employed to compensate the unbalanced currents caused by single-phase loads that are attached crosswise the two terminals of the three-phase SEIG. So the SEIG is able to feeding single-phase loads up to its rated power. Also the STATCOM regulates the SEIG terminal voltage through reactive power compensation and also suppresses the harmonics injected by consumer loads. A single-phase synchronous D-Q frame theory-based control algorithm is used to generate gating pulses to the three-phase STATCOM. The routine of the SEIG–STATCOM system is evaluated for both linear and nonlinear singlephase loads. Existing method: The obtainable STATCOM-based controller for SEIG systems, all the purposes of a STATCOM such as current balancing, voltage regulation, and harmonic currents suppression are not experimentally demonstrated .The presented simulation of the PI (Proportional plus Integral) controller-based control scheme for voltage profile improvement using the STATCOM. The major drawback of the PI controller-based control scheme is its instability under transients as it does not consider load currents while estimating the amplitudes of active and reactive components of reference source currents. The outputs of the STATCOM’s dc-bus voltage PI controller and the system ac voltage PI controller are directly considered as the amplitudes of active and reactive components of reference source currents, respectively. Proposed method: This dissertation proposes a single-phase synchronous D-Q frame based control algorithm for a three-phase STATCOM system, which is capable of producing balanced source currents even under heavy unbalance currents and voltages caused by single-phase loads.

Advantages: 1) The benefit of integrating a STATCOM in an SEIG based standalone power generation feeding single-phase loads is threefold first generator currents balancing; second, voltage regulation; and third, mitigates the harmonics injected by nonlinear loads. 2) The proposed a control algorithm for the STATCOM in frequency perturbed systems to avoid loss of synchronization under random varying loads. Applications: 1) The future method applicable for domestic loads and industrial loads, renewable generating systems, grid connected loads. 2) This proposes a single-phase synchronous D-Q frame based control algorithm for a threephase STATCOM system, which is capable of producing balanced source currents even under heavy unbalance currents and voltages caused by single-phase loads.
