Abstract
This paper addresses a systematic approach based on Eigen structure assignment to determine the mode shape and transient response of a STATCOM utilized as an exciter for induction generators (IG). A physical control scheme, including four control loops: ac voltage, dc voltage, ac active current and ac reactive current controllers, is pre-specified for the STATCOM. A synthetic algorithm is proposed to embed these physical control loops in the output feedback path. With appropriate oscillation mode design (Eigen structure) in each state variable, the STATCOM active current and reactive current will no longer be governed by the same mode but driven by new respective modes. The simulation and experimental results demonstrated that under various system disturbances, the proposed mode decoupling STATCOM is effective in regulating IG terminal voltage.
