Shunt Active Power Filter for Remove Harmonics Using Conventional PI and Fuzzy Logic Controllers
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 3
Abstract
The widespread use of power electronics devices such as inverter, rectifier, and so on. in power systems causes severe problems linked to power quality. The widespread use of nonlinear single-phase power electronic devices in the low voltage side has increased harmonic pollution in power systems to the large extent. One such problem is the generation of current and voltage harmonics causing the distortion of load waveform, heating of equipment, voltage fluctuation, voltage dip, etc. This paper provides a detailed study of shunt active power filter under two current control strategies, namely, p–q and d–q; their comparative analyses are performed to determine which method is better than the other. In both methods, a reference current is generated for the filter, which compensates either the reactive power or the harmonic current component in a power system. In this work, a current controller, known as the harmonic current controller, is described, which is used to provide remedial gating sequence of the IGBT inverter and thus helps remove the harmonics component. For proper pulse generation, conventional PI controller and fuzzy logic controller are used in this paper. A comparison of both the controllers is conducted, which highlights the superiority of the fuzzy logic control scheme.
