Design of active filters to reduce harmonics for Power Quality improvement

Delivering high quality of power to the consumers has become an indispensable issue of concern to power engineers. There are various issues regarding power quality of which harmonics affect the power system operation and their mitigation should be given paramount importance. Harmonic filters are used to address this issue. Of the various types of harmonic filters, Active harmonic filters are seen as a very much feasible and affordable solution and their commercial implementation is being researched by a lot of people. This paper discusses the simulation of an Active power filter to mitigate harmonics in single phase system using MATLAB / Simulink.
