Performance Improvement of Active Power Filter using a New Control Strategy under Unbalanced Grid Voltage

Tali Mouna

In this paper, the active power filter is discussed and proposed in order to improve power quality. It has been proved to be an efficient way to compensate harmonic currents and reactive power generated by nonlinear loads which affect and degrade the power quality under any voltage conditions: balanced and unbalanced condition. The APF proposed in this paper uses a new approach of detecting compensation currents using mixed coordinates and also uses a new control for VDC regulation. This method is proposed for simplicity of the control circuit of the active power filter. To verify the effective performance of the proposed method, simulations are presented in Matlab /Simulink.

Keywords: shunt active power filter, Total Harmonic Distortion THD and Non Linear Load
