A novel hybrid series active power filter to eliminate harmonics and compensate reactive power is presented and analyzed. The proposed active compensation technique is based on a hybrid series active filter using ATS algorithm in the conventional Sinusoidal Fryze voltage (SFV) control technique. This chapter discusses the comparative performances of conventional Sinusoidal Fryze voltage control strategy and ATS-optimized controllers. ATS algorithm has been used to obtain the optimum value of Kp and Ki. Analysis of the hybrid series active power filter system under non-linear load condition and its impact on the performance of the controllers is evaluated. MATLAB/Simulink results and Total harmonic distortion (THD) shows the practical viability of the controller for hybrid series active power filter to provide harmonic isolation of non-linear loads and to comply with IEEE 519 recommended harmonic standards. The ATS-optimized controller has been attempted for shunt active power filter too, and its performance has also been discussed in brief.

Abstract: Active Power Filters (APF) are more effective than conventional passive filters with regard to mitigating harmonics and compensating reactive power. As a result, deployment of APF in the distribution network is ever increasing. The performance of APF mainly depends on the reference extraction technique adopted. This work proposes sliding Discrete Fourier Transform (DFT) assisted single phase p-q theory for the extraction of reference current. The proposed algorithm exploits the inherent ability of sliding DFT (SDFT) to provide the fundamental and its quadrature component of signal (voltage or current) to derive the reference current with the help of a single-phase p-q theory. Furthermore, the algorithm involves the phase shifting of the fundamental component alone, and is suitable even for distorted utility voltage. Effectiveness of the proposed method is demonstrated through simulation results.

Power Quality Improvement

A new control strategy for active power filters is proposed, modeled and implemented in order to improve the power quality of a line commutated converter High voltage DC link. The ability of reactive power and harmonics reductions are generally met by using passive and active power filters. In this paper, modified active power filter with a modified harmonics pulse width modulation algorithm is used to minimize the source harmonics and force the AC supply current to be in the same phase with AC voltage source at both sending and receiving sides of a line commutated converter high voltage DC link. Therefore, it is considered as power factor corrector and harmonics eliminator with random variations in the load current. The modified harmonics pulse width modulation algorithm is applicable for active power filter based on a three-phase five-level and seven-level cascaded H-bridge voltage source inverter. Simulation results show that the suggested modified multilevel active power filters improve total harmonics distortion of both voltage and current with almost unity effective power factor at both AC sides of high voltage DC link. Therefore, modified active power filter is an effective tool for power quality improvement and preferable for line commutated converter high voltage DC link at different load conditions.

Contrast Analysis

With the wide application of power electronic equipments in power system, more and more harmonic are poured into the power system, which cause power pollution and make the power quality problem increasingly serious. Active power filter (APF) is an important equipment to compensate harmonic and reactive current in power system. One of the key technologies lies in the real-time and accurate control. The fundamental principles of several control strategies of compensate current were presented, and the respective merit and demerit of these control strategies were pointed out with contrast analysis in this paper. Active power filter will achieve a higher performance and a wider application with the continuous development of the control strategy.

<span>This paper presents a novel shunt active power filter (SAPF). The power converter that is used in this SAPF is constructed from a four-leg asymmetric multi-level cascaded H-bridge (CHB) inverter that is fed from a photovoltaic source. A three-dimensional space vector modulation (3D-SVPWM) technique is adopted in this work. The multi-level inverter can generate 27-level output with harmonic content is almost zero. In addition to the capability to inject reactive power and mitigating the harmonics, the proposed SAPF has also, the ability to inject real power as it is fed from a PV source. Moreover, it has a fault-tolerant capability that makes the SAPF maintaining its operation under a loss of one leg of the multi-level inverter due to an open-circuit fault without any degradation in the performance. The proposed SAPF is designed and simulated in MATLAB SIMULINK using a single nonlinear load and the results have shown a significant reduction in total harmonics distortion (THD) of the source current under the normal operating condition and post a failure in one phase of the SAPF. Also, similar results are obtained when IEEE 15 bus network is used.</span>
