The combination of space vector and one-cycle control method could make the controller structure much simple in three-phase three-wire active power filter (APF) with one-cycle control method. But in traditional methods, 6 sextants are divided at a frequency cycle in the whole range of space vector area. In this paper, the whole 6 sextants are divided in a novel method and section 1&2, section...
For the problems of fundamental frequency changes and the presence of harmonic and interharmonic in microgrid, which bring difficulties to the harmonic analysis of the microgrid, this paper presents a new harmonic and interharmonic analysis method based on cubic spline interpolation algorithm to reconstruct the signal. The simulation results show that the new harmonic and interharmonic analysis method...
With the proliferation of nonlinear loads as power electronics equipment, the disadvantage of harmonics is more and more, which influence quality of power grid. Active power filter is a new harmonics restraint method comparing with passive filter, which is a power electronics device. This paper inspects harmonics current based on three-phase circuit instantaneous reactive power theory and simulates...
