Abstract

The best solution for the elimination of harmonics and hence improving the power quality in distribution
systems is by the usage of filters. The resonance among the line inductance and correction capacitors leads to harmonic
propagation in the power distribution systems. Installing the shunt hybrid filter at the end bus of a distribution feeder is
one of the possible solutions to mitigate the harmonic propagation. This paper presents the design and simulation hybrid
active filter based on voltage detection consisting of seventh-tuned LC passive power filter and a 3???? active power filter
connected in series to mitigate the harmonic propagation under the worst-case situation that is under no load. The filter
is connected in parallel to the system. Simulation is carried out for a 415V, 50Hz system in MATLAB. The THD is
reduced from 19% without filter to 1.5% with the addition of hybrid filter
