| Abstract |
This paper presents a single-phase shunt active
power filter for current harmonic compensation based on
neural filtering. The shunt active filter, realized by a current
controlled inverter, has been used to compensate a nonlinear
current load by receiving its reference from a neural
adaptive notch filter. This is a recursive notch filter for the
fundamental grid frequency (50 Hz) and is based on the use
of a linear adaptive neuron (ADALINE). In this way the
inverter creates a current equal in amplitude and opposite
in sign to the load harmonic current, thus creating an
almost sinusoidal grid current. The methodology has been
applied in numerical simulations and experimentally on a
properly devised test setup. With this regard, a reduced
scale electrical grid has been built and used for assessing
this methodology. |
