Abstract

A novel design technique for an SVC-based power system damping controller has been proposed. The controller attempts to place all plant poles within a specified region on the s-plane to guarantee the desired close loop performance. The use of Horowitz's quantitative feedback theory (QFT) permits the design of a "fixed gain controller" which maintains its performance in spite of large variations in the plant parameters during its normal course of operation. The performance of this robust controller has been evaluated on a single machine infinite bus system equipped with a mid point SVC and the results are shown to be consistent with the expected performance of the stabilizer.
