摘要: This paper developed a novel single-phase reactive current detection algorithm based on fast orthogonal signal generator (OSG) and enhanced moving average filter (MAF), overcoming the limitation of conventional schemes in speed, computation burden noise/harmonic immunity. A accurate OSG scheme is introduced first, which can remarkably improve precision response speed scheme. In d-q frame, MAF its optimal design principle also presented, sufficiently eliminate noise harmonics while achieve possible shortest time, particularly case selective cancellation. Finally, high-performance STATCOM control realized utilizing proposed method. Experiments reveal that exhibits high as well noise/harmonics immunity, providing satisfactory performances.
