Performance of PQ theory based Seven- level Cascaded Shunt Active Power Filter using PI, Fuzzy and ANFIS controllers for Harmonic Reduction

Abstract

This paper presents a PI and Fuzzy Logic controller based Cascaded Seven- level Shunt Active Power filter for harmonic suppression and reactive power compensation. This device is controlled by means of PQ theory and the gate signals for SAPF are generated by LSCPWM. Later ANFIS controller is implemented for the control of proposed SAPF. Performance of proposed Seven level SAPF is studied for different loading conditions using PI, Fuzzy Logic and ANFIS controllers. The effectiveness of ANFIS controller is compared with other conventional controllers. Proposed work is simulated using MATLAB/ SIMULINK and results are tabulated.
