Design and prototyping of single‐phase shunt active power filter for harmonics elimination using model predictive current control

Abstract

Summary A model predictive current control (MPCC)‐based single‐phase shunt active power filter (SAPF) is proposed in this manuscript to improve power quality by harmonics and reactive power compensation. The DC link capacitor voltage regulation‐based PI control algorithm is used for the computation of SAPF reference current signal. The current commands are tracked using the MPCC. In this manuscript, the control technique effectiveness is demonstrated through MATLAB simulation and experimentation with Cyclone‐IV EP4CE30F484 FPGA board under dynamic operating conditions. The obtained results from a simulations and hardware prototype shows the proposed algorithm shows perfect reference current tracking at every sampling instant and excellent dynamic performance. Subsequently, the main advantages of this proposed controller are absence of internal current control loops and modulation stage.

Design and Implementation of Active Power Filter for Harmonics Elimination using Intelligent Control Controller

“…The main advantage of the SAPF, it is work independently and tackles at a time more than one harmonic. This is particularly used for huge and deform loads [10]. Figure 1 illustrates the SAPF concept.…”

“…Capacitor is reducing ripple voltage. The DC side capacitor is as follows [15][16]: (10) Where, is voltage ripple (peak to peak) and is rated filter current The PWM converter (K C ) transfer function is the ratio of input voltage ( ) to output capacitive current ( ) [15][16]: Figure 2 illustrated of fuzzy logic controller model. The FLC system follows some steps.…”

A Multifunctional Smart Meter Using ANN-PSO Flux Estimation and Harmonic Active Compensation with Fuzzy Voltage Regulation

“…Measurements of power flow and harmonic content were performed based on the instantaneous power theory (pq theory), which identifies the harmonic currents injected by nonlinear loads as oscillating power components [ 8 ]. In that sense, the proposed system contains an active power filter (APF) not only for the compensation of harmonics but also to compensate for the reactive power flow [ 9 ].…”

Model predictive control with constant switching frequency for four‐leg DSTATCOM using three‐dimensional space vector modulation

“…A single-phase shunt active filter is controlled using MPC to compensate for reactive and harmonic currents. However, most of the industries use three-phase supply which makes it a non-viable option for industrial applications [23]. Predictive control of a threeleg DSTATOM is proposed to compensate for reactive power [24].…”
