“…According to [23] the SRF is certainly a particular case of the P Q theory, for that in both cases we noticed the same results for both methods. We can noticed that low pass filter LPF is more perform than the high pass filter HPF used with the P Q and SRF filters.…”

In the present work a technical review of several algorithms of harmonic currents compensation has been presented. The instantaneous reactive power theory (P Q theory), the Multi-Variable Filter FMV and Synchronous Reference Frame have been analyzed and compared under distorted and unbalanced conditions. The adopted strategy consists in first time in imposing a constant time response then the THD of the fundamental signal delivered by each method is computed; in second time the reversal case is considered; a THD value is imposed then the time response constant of each method will be computed. The simulation results obtained have been verified experimentally using Dspace 1104 platform.

“…The basic requirements for compensation process involve precise control with fast dynamic response and on-line elimination of load harmonics. The traditional compensation methods using switched capacitor and thyristor controlled inductor [1][2] coupled with passive filters are increasingly replaced by active power filters (APFs) [3][4]. The two types of APFs are shunt and series APF, the shunt APFs are used to mitigate current harmonics and reactive power compensation.…”

-This paper proposes a simplified and efficient control scheme for Unified Power Quality Conditioner (UPQC) based on three-level (NPC) inverter capable to mitigate source current harmonics and compensate all voltage disturbances perturbations such us, voltage sags, swells, unbalances and harmonics. The UPQC is designed by the integration of series and shunt active filters (AFs) sharing a common dc bus capacitor. The dc voltage is maintained constant using proportional integral voltage controller. The shunt and series AF are designed using a three-phase three-level (NPC) inverter. The synchronous reference frame (SRF) theory is used to get the reference signals for shunt and the power reactive theory (PQ) for a series APFs. The reference signals for the shunt and series APF are derived from the control algorithm and sensed signals are injected in tow controllers to generate switching signals for series and shunt APFs. The performance of proposed UPQC system is evaluated in terms of power factor correction and mitigation of voltage, current harmonics and all voltage disturbances compensation in three-phase, three-wire power system using MATLAB-Simulink software and SimPowerSystem Toolbox. The simulation results demonstrate that the proposed UPQC system can improve the power quality at the common connection point of the non-linear load.

“…Each 6-pulse converter switches at fundamental frequency which presents losses during steadystate operation less than the losses presented by the PWM-STATCOM [1]. In its dc side, the STATCOM has a capacitor and is connected to the ac system through one or more transformers, depending on the number of pulses (6,12,24 or 48 pulses).…”

“…Active filters would be a better solution to compensate the oscillatory component of active power. In [6], Casaravilla et al use a shunt active filter to reduce the harmonic distortion in an arc furnace installation. Often, hybrid configurations can be the choice to obtain a complete compensation.…”

This paper proposes a new technique to compensate fast oscillating reactive power using a multipulse STATCOM. It is shown that the oscillating reactive power can be controlled in a simple way by maintaining the STATCOM dc voltage constant. A simplified analytical analysis was performed in a power system with an arc furnace and a 12-pulse STATCOM. The study has shown that the STATCOM can compensate the furnace reactive current, even when fast oscillations occur. The system studied was implemented in a detailed EMTP/ATP simulation program. The results show that the reactive power oscillations produced by the furnace can be strongly reduced. However, due to the fact that arc furnace is an unbalanced load, STATCOM dc side capacitor has to be designed to supply the corresponding oscillating energy.
