Abstract
This paper proposes a ne
w active damping method
based on virtual resistors for three-phase grid connected voltage
source inverters (VSI) with LCL filter. The use of this filters is a
standard solution to provide the proper attenuation to the
sideband voltage harmonics of
the modulation signal. However
these grid filters can introduce an unstable dynamics if a passive
or active damping is not pr
operly introduced. The passive
damping solution causes a decrease of the overall efficiency due to
the associated losses and reduces the filter effectiveness but in
contrast no more extra sensors are needed. Active damping
methods are more efficient because they don’t introduce losses but
suffers from control and system complexity because in some cases
a high number of sensors are
needed. The proposed strategy
employs a nonlinear sliding mode control (SMC) scheme in
natural frame in combination with a Kalman filter to emulate a
resistor in the LCL filter which damps the system actively without
the use of extra sensors. Two current controllers are designed in
order to control the active and reactive power independently and
a voltage controller is designed to control the neutral point which
is fixed with a third harmonic vol
tage in order to increase the
control dynamic range.
