Operating performance of static series compensated three-phase self-excited induction generator

The performance of three-phase self-excited induction generator (SEIG) is investigated with static synchronous series compensator (SSSC) and static compensator (STATCOM) to feed static and dynamic loads. The employed compensators are three-phase, Insulated Gate Bipolar Transistor (IGBT) based, Pulse Width Modulation (PWM) operated, Current-Control Voltage Source Converter (CC-VSC). The proposed control techniques employ proportional-integral (PI) controller to generate the reference current. With the designed parameters and control, the SSSC is found effective to regulate load voltage during sudden change of the loads. The SSSC also provides stable operation with dynamic induction motor load and mitigates the unstable and oscillating behavior that is resulting during the operation of compensated SEIG with dynamic motor load. The presented results prove that both SEIG-SSSC and SEIG-STATCOM systems provide satisfactory performance. (C) 2013 Elsevier Ltd. All rights reserved.
