摘要

The authors suggest to use hybrid modulation schemes to improve the reactive power compensation capabilities of the direct AC-AC FACTS device composed of a matrix converter and a permanent magnet machine. Because of the intrinsic limitations of the conventional matrix converter modulation schemes, the device has so far displayed a poor reactive power compensation capability when the output power factor is low. Even worse, the direct AC-AC FACTS device could not provide pure reactive power compensation. The paper presents an analysis demonstrating how the hybrid Three-Vector-Scheme extends the reactive compensation range beyond the level that the conventional indirect space vector modulation exhibits. The reactive power compensation capabilities of the FACTS device with both modulations are computed and compared analytically and finally verified by a simulation study.
