Performance of self-excited induction generator with cost- effective static compensator

The performance of a system consisting of a three-phase self-excited induction generator (SEIG) with static compensator (STATCOM) for feeding static resistive-inductive (R-L) and dynamic induction motor (IM) loads was investigated. The cost-effective STATCOM providing stable operation was designed by connecting additional shunt capacitance with the load. The STATCOM-controlled algorithm was realised by controlling the source current using two control loops with proportional-integral (PI) controller: one for controlling the SEIG terminal voltage and the other for maintaining the DC bus voltage. The SEIG-STATCOM performance was studied for two designs of STATCOM, namely cost- effective STATCOM and full-rating STATCOM. The cost-effective SEIG-STATCOM system with the proposed control scheme exhibited improved performance with respect to starting time, voltage dip, generator current and total harmonic distortion under various transient conditions.
