Improving the dynamic response of shunt active power filter using modified Synchronous Reference Frame PLL

This paper proposes a novel phase-locked loop (PLL) control strategy to synthesize unit vector using the modified synchronous reference frame (MSRF) instead of the traditional synchronous reference frame. The unit vector is used for vector rotation or inverse rotation in vector-controlled three-phase gridconnected converting equipment. The developed MSRF-PLL is fast in transient response compared to standard PLL technique. The performance is robust against disturbances on the grid, voltage wave with harmonic distortion, and noise. The proposed algorithm has been analyzed in detail and was fully implemented digitally using digital signal processor TMS320F2812. The experimental evaluation of the MSRF-PLL in a shunt active power filter confirms its fast dynamic response, noise immunity, and applicability.Index Terms-Active filter, digital signal processor (DSP), phase-locked loop (PLL), synchronous reference frame (SRF).

“…As examples of conventional and intelligent control methods of the SAPF, there is; Instantaneous Reactive Power Compensation [14], Output Feedback Control [15], this method tried to overcome the non-linearity of classical control methods by presenting a linearized model, it gives a good THD for the supply source voltage but the obtained current THD was out of standards. Also there is Synchronous Reference Frame PLL [16], Dynamic Surface Adaptive Fuzzy Control [17] and Adaptive Fuzzy-Neural-Network based on RBFNN control, this recent proposed method suffer of some technical difficulties related to the accuracy of harmonics detection [18], etc. As part of the integration of renewable energy into the generation mix and total production of electricity and the improvement of its quality, in this paper a hybrid filter is proposed in two cases.…”

This paper presents a modified hybrid Controller based on instantaneous power-fuzzy controller (IPFLC) for a shunt active power filter (SAPF). The current produced by the AC source is polluted by harmonics injected by the non-linear loads. The supply system requires filtering by suppressing harmonic currents to improve power quality at interface bus. The filtering system consists of an LC filter and a SAPF. The proposed IPFL Controller for the SAPF is based on a combination of the p-q instantaneous power and the fuzzy logic strategy. In this part, two cases are studied, first the active filter is connected only to a capacitor by its dc side, and second case where the active filter is connected to a photovoltaic source or to a battery. The effectiveness, robustness and the dynamic speed of the proposed controller is validated and assessed using dynamic digital simulation. Digital Simulation results validated also the effectiveness of the active filter scheme with modified controller in reducing the source current THD from 25.87% to 0.83% which largely meets the standards of IEEE STD and International Electro-technical Commission (IEC). Digital Simulation and validation used MATLAB-SIMULINK Software Environment.

“…In the time domain control algorithms used for PAPF, the derivatives of current signal are calculated. Commonly-used time domain control algorithms are the instantaneous active and reactive power based algorithms [9][10][11][12], synchronous reference frame SRF based algorithms [3,[13][14][15][16][17]. But, SRF based control algorithms show superior performance compared to PQ based algorithms [18].…”

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.
