“…The closed loop scheme of shunt active power filter using FFT reference current generation is shown in Fig.4. The amplitude and phase information of the harmonic series in a periodic signal can be calculated by using the fourier analyzer block shown in Fig.5 [13,14]. Dominant harmonics have been detected by running the m-file scripts in embedded matlab function block.…”

Abstract-Generation of current references constitutes an important part in the control of active power filters (APFs) used in power system, since any inaccuracy in reference currents yields to incorrect compensation. In this paper, two different harmonic detection methods for generating reference currents have been evaluated. The approach is based on the measurement of line currents and performs the compensation of the selected harmonics using closed-loop control. MATLAB/SIMULINK power system toolbox is used to simulate the proposed system. Simulation results show that the dominant harmonics in the line current are reduced significantly and thereby there is a marked reduction in the total harmonic distortion.Index Terms-Active power filters, harmonic compensation, multilevel inverters, non linear loads and power quality.

“…PAF cancel harmonic currents flowing to the supply due to nonlinear load by operating as a current supply. Therefore, they protect the system from harmonics by generating currents at the same amplitude which are in opposite phase to harmonic currents [21][22][23]. Thus, sum of currents generated by load and active filter eliminates each other, and harmonic currents flowing into the mains are prevented for this way.…”

“…In recent years, the GSSA method, AC/DC inverter is used quite a lot of mathematical modeling in the literature [21][22][23]. A new approach is presented as a novel GSSA model for the system analysis, control and characterization of Advanced Aircraft Electric Power Systems AAEPS by Ebrahimi et al in their study [24][25].…”

This work aims to improve well known generalized averaged models for mathematical modelling of parallel active filter (PAF) with voltage supply. To achieve this task, the method is adopted to generalized state space averaging (GSSA) method. Non-linearity of the system is removed by using GSSA method. Relation between the state variables of the system is expressed by linear equations. An exact and fast approximation of the system parameters is achieved. Non-linearity of real elements that causes many problems such as long execution time, divergence, and huge produced files do not exist thanks to the method. A single phase full-bridge voltage supply inverter is proposed as a parallel active filter. A diode rectifier with RL load is used as a nonlinear load. In this study, simulation results of parallel active filter mathematically modeled with GSSA model are compared to real-time designed simulation results of parallel active filter realized power simulation with PSIM software. In the results obtained through mathematical models with real model has been observed that a good match.

“…In this paper, two methods are considered and compared. One of them is the instantaneous reactive power theory (IRPT) method [6,7] which is generally used for balanced three phase loads. Performance of this method is a function of characteristics of the digital filter and execution time of programmable device.…”

SUMMARYIn this paper, a shunt active filter based on adaptive linear neuron (ADALINE) method is analyzed. The ADALINE that is used here as the harmonic extraction method is implemented with the measurement of load current under the direct and indirect techniques. The response of method to the loading conditions is compared to that of the instantaneous reactive power theory (IRPT) method. TMS320F2812 digital signal processor (DSP) is employed as a central processing unit in experimental works.
