Abstract:
In the modern power system, harmonics are serious concerns for power system engineers due to the increasing use of nonlinear loads. This paper deals with reducing the supply current harmonics in an induction motor drive using solar PV powered Fuzzy logic controlled Zeta converter fed Shunt Active Filter (FLC ZCSAF). Numerous research works are addressed to reduce the harmonics by using active filters connected at the load end. This paper presents a new topology of introducing the shunt active filter (SAF) at the supply end to reduce source current harmonics, enhance the power quality and improve the performance of VSI fed induction motor drive. In this system, a simple and efficient method of increment conductance based MPPT algorithm is used for obtaining the peak power from solar PV array panels. The PI and FL controlled solar PV supplied zeta converter fed SAF system has been modeled and simulated using MATLAB/Simulink software. The results indicate that using a fuzzy logic controller, supply current harmonics are greatly reduced. The simulation result obtained using PI and Fuzzy logic controllers were compared and discussed. The experimental setup has been developed to validate the simulation results.
