“…SRF control algorithm is used in P-APF. The source voltages (VSabc), DC bus voltage (Vdc), source currents (iSabc) or load currents (iLabc) are realized by taking a total of seven measurement values in the conventional SRF control algorithm [9]. In the conventional SRF algorithm, the d and q values of the source or load currents are obtained by using Eq.…”

In a modern power system with the increasing use of power electronics components, nonlinear loads connected to the grid cause power quality problems. To overcome the power quality problems, the parallel active power filter PAPF is used in power systems. In this study, the synchronous reference frame based a new control algorithm is proposed for the three-phase PAPF system. In the proposed control algorithm, synchronous reference frame SRF method and moving average filter MAF filter and space vector pulse width modulation SV-PWM technique are used to obtain low total harmonic distortion and high power factor. SRF method and MAF filter are used to calculate the reference current signal. SV-PWM technique is used to obtain the switching signals of active switches used in power filters. In the proposed algorithm, the number of measurements is reduced and performance is increased by using source ab currents and ab voltages without filter abc currents and abc voltages and load abc currents. Simulation studies of the proposed control algorithm have been tested using PSIM software. According to the simulation results, it is seen that the proposed control algorithm is more successful in eliminating the harmonics in the source current and compensating the reactive power than the other control method used in the literature.

“…By far, some active harmonics elimination methods have been proposed to address this problem, such as active power filters (APF) and unified power quality conditioner (UPQC), etc. [5]- [10]. Among all the active harmonics elimination methods, harmonic detection is one of the most critical technology for harmonic governing and control, because controllers of power inverter containing a fast harmonic current detection method will lead a fast harmonics response for the power inverter.…”

“…In previous studies, many methods for detecting the power grid harmonics or the fundamental have been proposed, which can be divided into time-domain method, frequency-domain method, and intelligent algorithm based method. First, the common time-domain methods proposed by researchers include instantaneous reactive power theory (IRPT) method [10][11], synchronous reference frame (SRF) method [12], the second-order generalized integral (SOGI) method [13], the cascaded delayed signal cancellation (CDSC) techniques [14] and the Kalman filter method [15], etc. Traditional IRPT and SRF play an important role in conventional harmonics detection for APF and UPQC, and in recent years, IRPT and SRF are improved for more complex applications with the better performance [16]- [17].…”

Harmonic current estimation is the key technology of power electronics systems to generate a harmonics reference current for harmonic control. In this paper, a novel fundamental and harmonic current detection method based on the state-space model (SSM) is introduced. The proposed SSM harmonics detection method has the ability to detect the positive sequence component (PSC), negative sequence component (NSC), and zero-sequence component (ZSC) of both fundamental and each order harmonics current with fast response and high accuracy separately, including the fundamental component, which is appealing for harmonics control in power electronic applications, such as active power filter (APF), unified power quality conditioner (UPQC), virtual synchronous generator (VSG), and so on. The correctness of the proposed SSM based harmonics detection method has been verified by simulation and experiment result, and it shows that the PSC, NSC, and ZCS of the grid fundamental and high order harmonic current can be detected quickly and accurately, which is important for harmonics analysis and control in the power electronics system.

Power quality is a comprehensive term used to estimate the caliber of the power system in delivering high-grade supply and is an interesting study to ensure customer satisfaction. DSTATCOM is one of the custom power devices used to refine the power system parameters especially to ensure that the source current contains acceptable harmonic limit. Parallel connected DSTATCOM is a topology with two parallel DSTATCOMs connected to the point of common coupling for harmonic reduction in source current and improving the power quality. Each of the two parallel DSTATCOMs has its individual DC storage source to adjust the real power deficit to the system (during load transients). This paper presents a common DC-Link fed parallel DSTATCOM topology for power quality improvement. Unlike the conventional parallel DSTATCOM topology, common DC-Link fed parallel DSTATCOM topology employs only one DC-Link source reducing the number of DC sources, cost and increases reliability. The single DC storage source adjusts the real power deficit to the system. In this paper, IRP control methodology delivers the control pulses to parallel DSTATCOM. The proposed system is tested with variable and constant load operations and the results are presented using MATLAB/SIMULINK software.
