With the increasing use of non-linear loads, the harmonic problems have become of great concerns. One of the solutions to harmonics is the application of shunt active power filters (APFs). The APF reference compensation strategy proposed in this paper adopts the backpropagation neural network (BPNN) to train the control algorithm and calculate the reference compensation current under steady state...
This paper presents a study of applying the equivalent effective voltage concept according to IEEE Standard 1459-2010 for determining reference compensation currents of the three-phase three-wire shunt active power filter in the a-b-c reference frame. The APF reference current calculator is developed and is realized on the DSP board through processor-in-the-loop simulation for validating the effectiveness...
The deployment of ac microgrids including distributed energy resources (DERs) can reduce the investment cost of building new fossil-fuel based power plants, facilitate the carbon-oxide reduction, provide reactive power compensation and frequency regulation, increasing spin reserve, and enhance the system stability. However, some undesired effects such as imbalance, voltage fluctuation, and harmonics...
This paper presents an approach of incorporating hardware-in-the-loop simulation and ADALINE for shunt active power filter (APF) design. Even when the three-phase source voltages are unbalanced and/or distorted and supply to a nonlinear load, the described compensation strategy can compensate the harmonic and neutral current, and thus improve the power factor. After verifying the efficiency of compensation...
