Title: | A novel single-phase reactive current detection algorithm based on fast orthogonal signal generator and enhanced moving average filter | Authors: | Xiong, LS Liu, XK Zhu, YX Xu, Z Yang, P Song, HL |
Issue Date: | 2018 | Source: | Energies, Apr. 2018, v. 11, no. 4, 733, p. 1-12 | Abstract: | 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 detection speed, computation burden and noise/harmonic immunity. A fast and accurate OSG scheme is introduced first, which can remarkably improve the precision and response speed of the developed detection scheme. In d-q frame, the enhanced MAF is developed and its optimal design principle is also presented, which can sufficiently eliminate the noise and harmonics while achieve the possible shortest response time, particularly in the case of selective harmonics cancellation. Finally, high-performance single-phase STATCOM control is realized utilizing the proposed method. Experiments reveal that the proposed detection scheme exhibits fast speed, high precision as well as noise/harmonics immunity, providing satisfactory control performances. | Keywords: | Reactive current detection OSG Enhanced MAF Single-phase STATCOM |
