| Resum: | This paper presents a new multiresonant frequencyadaptive
synchronization method for grid-connected power
converters that allows estimating not only the positive- and
negative-sequence components of the power signal at the fundamental
frequency but also other sequence components at other
harmonic frequencies. The proposed system is calledMSOGI-FLL
since it is based on both a harmonic decoupling network consisting
of multiple second-order generalized integrators (MSOGIs) and a
frequency-locked loop (FLL), which makes the system frequency
adaptive. In this paper, the MSOGI-FLL is analyzed for singleand
three-phase applications, deducing some key expressions regarding
its stability and tuning. Moreover, the performance of the
MSOGI-FLL is evaluated by both simulations and experiments to
show its capability for detecting different harmonic components in
a highly polluted grid scenario. |
