Design and Simulation of Three Phase Shunt Active Power Filter Using SRF Theory
نویسنده
چکیده
Active power filters are widely used for the reduction of harmonics in the power system caused by nonlinear loads. The Shunt Active Power Filter (SAPF) injects a suitable compensating current at a point of the line known as the point of common coupling (PCC) so that the harmonics present in the line are cancelled out and the sinusoidal nature of voltage and current waveforms are restored. A three phase current controlled voltage source inverter (VSI) with a DC link capacitor across it is used as an active filter. Synchronous Reference Frame (SRF) algorithm is used to extract the harmonic components. Hysteresis band current control (HBCC) technique is used for the generation of firing pulses to the inverter. This system is simulated using MATLAB/Simulink and the results are presented.

A Hybrid Control Method for Stable Operation of Active Power Filters in Three-Phase Four-Wire Networks
The main goal of this study is the use of Lyapunov’s stability theory to a three-phase four-wire shunt active power filter (SAPF), since this method has been applied effectively to other areas of converter. The dynamic model of the SAPF is first established, after that, a combination of fuzzy tracking control and Lyapunov function is suggested in order to impose a desired transient waveform on ...
