“…Active power filters(APFs) [1][2][3][4][5][6][7][8][9][10][11] have been accepting as an efficient device for compensating the harmonics and reactive power of nonlinear loads such as thyristor controlled rectifiers or variable speed drives. In order to compensate the harmonics and reactive power using APFs, APFs should be operated to the instantaneous rectification mode and the instantaneous inversion mode during the compensation operation.…”

-The conventional graphical representation of the instantaneous compensation power flow for single-phase active power filters(APFs) simply represents the active power flow and the reactive power flow which flowing between the power source and the active filter / the load. But, this method does not provide the information about the rectification mode and the compensation mode of APFs, especially, the loss for each mode was not considered at all. This is very important to understand the compensation operation characteristics of APFs. Therefore, this paper proposes the graphical representation of the instantaneous compensation power flow for single-phase APFs considering the instantaneous rectification mode and the instantaneous inversion mode. Three cases are verified in this paper -without compensation, with compensation of the active power 'p' and the fundamental reactive power 'q', and with compensation of only the distorted power 'h'. To ensure the validity of the proposed approach, PSIM simulation is achieved. As a result, we could confirm that the proposed approach was easy to explain the instantaneous compensation power flow considering the instantaneous rectification mode and the instantaneous inversion mode of APFs, also, Total Harmonic Distortion(THD)/Power Factor (P.F) and Fast Fourier Transform(FFT) analysis were compared for each case.

“…Under balanced and sinusoidal source voltage conditions, various research works on this particular algorithm have been reported in the literature such as synchronous reference frame (SRF) [20][21][22], instantaneous power (pq) theory [2,[23][24][25], dq-axis with Fourier (dqF) [26], fast Fourier transform (FFT) [27], synchronous detection (SD) [28,29] and artificial neural network (ANN) [30,31]. Nevertheless, among the available algorithms, pq theory algorithm provides the best advantages which include simple design, increased speed and fewer calculations, and thus makes it more likely to be implemented practically.…”

A Refined Self-Tuning Filter-Based Instantaneous Power Theory Algorithm for Indirect Current Controlled Three-Level Inverter-Based Shunt Active Power Filters under Non-sinusoidal Source Voltage Conditions

Abstract:In this paper, a refined reference current generation algorithm based on instantaneous power (pq) theory is proposed, for operation of an indirect current controlled (ICC) three-level neutral-point diode clamped (NPC) inverter-based shunt active power filter (SAPF) under non-sinusoidal source voltage conditions. SAPF is recognized as one of the most effective solutions to current harmonics due to its flexibility in dealing with various power system conditions. As for its controller, pq theory has widely been applied to generate the desired reference current due to its simple implementation features. However, the conventional dependency on self-tuning filter (STF) in generating reference current has significantly limited mitigation performance of SAPF. Besides, the conventional STF-based pq theory algorithm is still considered to possess needless features which increase computational complexity. Furthermore, the conventional algorithm is mostly designed to suit operation of direct current controlled (DCC) SAPF which is incapable of handling switching ripples problems, thereby leading to inefficient mitigation performance. Therefore, three main improvements are performed which include replacement of STF with mathematical-based fundamental real power identifier, removal of redundant features, and generation of sinusoidal reference current. To validate effectiveness and feasibility of the proposed algorithm, simulation work in MATLAB-Simulink and laboratory test utilizing a TMS320F28335 digital signal processor (DSP) are performed. Both simulation and experimental findings demonstrate superiority of the proposed algorithm over the conventional algorithm.

“…This paper presents the implementation of APF in order to verify the performance comparison of the PI and P+RES controllers. From the literature reviews, the control strategy for APF can be implemented by analog circuits (one cycle control [19], PI control [20], quasi steady state control [21]) and digital techniques (adaptive linear element (Adaline) control [22], PI control [23], hysteresis control [24], fuzzy logic control [25], predictive control [26], one cycle control [27]). The advantages of analog circuits are fast computational time (no sampling time) and low cost.…”

Abstract. This paper presents the harmonic elimination using an active power filter (APF) for three-phase system. The design and performance comparison study of the compensating current controllers are explained. The performance of the PI controller and the proportional plus resonant (P+RES) controller are compared in the paper. Moreover, the hardware implementation of the considered system is also presented in this paper. For the experimental results, the P+RES controller can provide a good performance to control the compensating current compared with using the PI controller.
