N2 - Fast and accurate detection of instantaneous reactive current in single-phase power system is a pre-requisite for the precise control of STATCOM (Static Synchronous Compensator). A major solution is based on the construction of virtual orthogonal signal in rotational coordinate transformation; however, conventional methods show weaknesses in the speed of detection and the ability of noise and harmonic suppression. In this paper, a novel method of instantaneous reactive current detection in single-phase system, with fast and accurate property as well as harmonic and noise susceptibility, is proposed. Firstly, a novel virtual orthogonal signal generation algorithm is deduced, remarkably improving the immediacy and precision of detection in synchronous reference frame. Then an enhanced moving average filter (EMAF) is utilized in cascade and its design principle is proposed, sufficiently eliminating the effects of noise and harmonics. Finally, experiments reveal that the proposed detection scheme can achieve the satisfactory control goals.
