“…High power modern semiconductor switches such as IGBTs GTOs and thyristors have enabled the practical incorporation of active power filters. These active devices used in distribution system are given a generic name as Custom Power devices and are discussed by Salmeron and Litran (2010), Brenna et al (2009). Distribution static compensator (D-STATCOM) type custom power devices which is connected in shunt to the load at the load center.…”

“…In this technique, it is assume that the frequency of the grid are constant and its only detect the harmonics in the system. Furthermore, the DC NLL have been used by many researchers to generate the distorted current waveform [5,[27][28][29][30][31]. Generally, the NLL is constructed using combination of resistor, inductor and capacitor (RLC).…”

-This paper presents a new technique of reference current generator based on Kalman filter (KF) estimator for three-phase shunt active power filter (APF). The stationary reference frame (d-q algorithm) is used to transform the load currents into DC component. The harmonics of load currents are extracted and the three-phase reference currents are generated using KF estimator. The work is simulated using Matlab/Simulink platform. To validate the simulation results, an experimental test-rig have been perform using real-time control dSPACE DS1104. In addition, hysteresis current control was used to generate the switching signal for the correction of the harmonics in the system. The nonlinear load were constructed with three-phase rectifier which connected in series with inductor and parallel with resistor and capacitor. The results shows that the new technique of shunt APF embedded with KF is proven to eliminate the harmonics created by the non-linear load with some improvement on the total harmonics distortion (THD).

ABSTRACT:In this work a new control strategy for simulation of three phase hybrid power filter for power quality improvement is adapted. This filter consists of shunt passive LC power filter and series active filter, with nonlinear balanced and unbalanced loads and also with variation in the source impedance. A new control method based on dual formulation of instantaneous reactive power vectorial theory is applied by considering a balanced and resistive load as reference load, so that the voltage waveform injected by the active filter is able to attain the objective of achieving reactive power compensation. This also helps in eliminating load current harmonics and also in balancing asymmetrical loads i.e., for achieving ideal behaviour for the set hybrid filter load, Total Harmonic Distortion (THD) is reduced and power factor is improved. This method improves passive filter compensation characteristics without depending on system impedance, avoids the danger of passive filter behaves as harmonic drain of close loads and avoiding series and / or parallel resonance problems. And compensation is also possible with variable loads without detuning the passive filter. And is applied for creating LG/LL faults at the source side. The results show that the active filter improves the compensation characteristics of the passive filter and reactive power is compensated.
