   Active Power Filter For Reactive Power And Harmonic Compensation
By S. Ramirez G., V. Cardenas, J. Arau [View]
[Download]

Abstract: This paper presents a series active power filter which is intended for compensating fundamental voltage drops caused mainly by transmission and distribution reactive impedance. Besides, the power filter compensates harmonic voltages produced by the costumers. The proposed structure increases the transmission capability of power systems. The power stage of the active power filter is based on a H-bridge multilevel inverter. This structure has shown to be a suitable alternative in high power applications. The paper also presents a very simple control circuit which agrees with the operating conditions of the system. The control circuit is based on a digital signal processor. Theoretical analysis and some experimental results are included.

   Comparison Of Three-Phase Shunt Active Power Filters With Control Based On The P-Q And The Currents Physical Components Theories
By Andrzej Firlit [View]
[Download]

Abstract: The subject of this paper is comparison of the threephase shunt active power filters with control algorithms based on the p-q power theory and the theory of current physical components. The comparison concerns aspects of: filtering current harmonics, reactive power compensation and load balancing, which can be carried out concurrently or individually. The active power filter operation for the distorted voltage at the point of common coupling and for non-zero internal source impedance is considered.

   Dsp Controlled Active Power Filter Modeling And Simulation Using Sympowersystems And Fixed Point Blocksets
By Alon Kuperman, Ronen Katz, Effi Goren, Raul Rabinovici [View]
[Download]

Abstract: This paper deals with a process of modeling and simulation of a control scheme for a parallel three-phase active power filter (APF) to eliminate harmonics and to compensate the reactive power of a nonlinear unbalance load. A threephase voltage source inverter bridge with a dc bus capacitor is used as an APF. A hysteresis based carrierless PWM current control is employed to derive switching signals to the APF. A three-phase diode rectifier with inductive loading is employed as a non-linear load, connected to the source through unbalanced transmission line. Source, transmission line, load, and APF are modeled using Matlab's SymPowerSystems, APF controller is modeled using Fixed Point Blockset and the whole system is simulated using Simulink. Extended simulation results are provided.

   Shunt Active Filter Control Based On Instantaneous Power Theory On A Rotating Reference Frame In 3-Phase Systems
By Ahmad Esfandiari, Mostafa Parniani, Hossein Mokhtari [View]
[Download]

Abstract: Shunt active filtering has a vital role in power quality improvement in utility and industry applications. It requires a high performance control strategy that can be used in real conditions. This paper presents a control method based on instantaneous power theory on a rotating reference frame. The method uses current vector components in a rotating frame for extracting reference compensation signals and modifying them for dc bus voltage regulation without need to a distinct synchronizing circuit. The proposed method can be used under balance and unbalance source voltages. Simulation results verify the effectiveness of the control method.

   Shunt Active Power Filter Based On D-Q Reference Frame Control Strategy
By A. A. Mansour, A. M. Zaki, O. A. Mahgoub, E. E. Abu-Elzahab [View]
[Download]

Abstract: Active Power Filters (APF's) represent the most convenient system used to overcome the harmonics generated by using the power electronics based loads. This paper introduces the control strategy of the three-phase shunt active filter for balanced three-phase systems based on d-q reference frame. The harmonics current reference is extracted using the Average Control Technique in order to be used in generating the compensation current signal. The average control technique is implemented using one current sensor which proved to be faster and easier in implementation than other techniques.

   Using Instantaneous Reactive Power Method For Single-Phase Power Active Filter - Theoretical And Experimental Approach
By J. Altus, L. H. Viet, J. Michalik, B. Dobrucky [View]
[Download]

Abstract: The paper deals with the new method of analysis, synthesis and experimentation of single-phase power active filters. By using a new particular transformation theory, the ordinary single-phase system can be transformed into an equivalent two-axes orthogonal one. The new original thought is based on the idea that ordinary single-phase quantity can be complemented by fictitious second phase so that both of them will create an orthogonal system, as is usual in three-phase systems, in spite of [1]. Application of the above theory makes it possible to use complex methods of analysis as the instantaneous reactive power method, which have not been usable for single-phase systems so far. Both, the active and reactive powers can be determined by this way. Practical application of the method is outlined for the case of reference current determination for single-phase power active filter. The paper shows some examples of the simulation verification results, which proved a high accuracy and extremely fast response of the single-phase active filter with control, based on the introduced method. The effectiveness of proposed control algorithm is also demonstrated by experimental results, which were carried out on the single – phase active parallel filter, power rate of 25 kVA and controlled by 32 – bit floating point digital signal processor TMS 320C31.
