Abstract:

In this study, a Shunt Active Power Filter-based new control method for power distribution system current harmonic removal is proposed (ShAPF). The Phase Locked Loop (PLL) based on Moving Average Filter (MAF) is used in the control technique to enhance the dynamic response of the control circuit. The fundamental frequency and phase angle of distorted voltage and/or current signals are found using the PLL. Nevertheless, the ShAPF's control circuit's typical PLLs have a slow dynamic response. A new control strategy based on MAF with PLL is implemented for disturbance extraction from the input signals to get over this limitation. By MATLAB-based simulations, the suggested control strategy is assessed for current harmonic elimination in a power distribution system serving harmonic sensitive loads. The reduction in total harmonic distortion (THD) of the current waveform serves as evidence of the efficiency of the suggested method. Overall, the suggested method provides a successful means of removing current harmonics in power distribution systems with harmonic-sensitive loads.
