Abstract
An active power filter implemented with
a four-leg voltage-source inverter using a predictive
control scheme is presented. The use of a four-leg
voltage-source inverter allows the compensation of
current harmonic components, as well as
unbalanced current generated by single-phase
nonlinear loads. A detailed yet simple mathematical
model of the active power filter, including the effect
of the equivalent power system impedance, is
derived and used to design the predictive control
algorithm. This proposed system is placed in a wind
and pv based power generation system. A Fuzzy
logic controller is used in the control block to
generate accurate control signals to the inverter
circuit. The compensation performance of the
proposed active power filter and the associated
control scheme under steady state and transient
operating conditions is demonstrated through
simulations and experimental results.
