Abstract:

This paper presents a comparative analysis between two current control strategies, constant source power and generalized Fryze current, used in Active Power Filter (APF) applications having three different modulation methods. The Hysteresis Band (HB) and first-order Delta-Sigma Modulation (DSM) as well as the second-order DSM is applied. The power section of the active power filter is viewed as an Analogue to Digital Converter (ADC), then as a result a three-phase shunt active filter modulator controller which, uses Delta-Sigma analogue to digital converter is presented to improve modulator performance. As a result, using second-order Delta-Sigma modulator makes low switching rate compared with first-order Delta-Sigma and hysteresis modulators under same sampling frequency. So, applying this modulator increases system efficiency and reduces cost of switches. In addition, simulation results on MATLAB software show that by using the Delta-Sigma modulator, Total Harmonic Distortion (THD) can be significantly decreased. Moreover, active filter based on the second-order DSM with constant source power has high efficiency and provides lower source current THD.

Active Filter Control Method Based on Direct Power Control for Compensating Reactive Powers due to Unbalanced Voltages and Nonlinear Loads

Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...

Genetic Algorithm- Based Active Power Filter Allocation and Size Determination

In this paper, two algorithms have been developed for allocation and size determination of Active Power Filters (APF) in power systems. In the first algorithm, the objective is to minimize harmonic voltage distortion. The objective in the second algorithm is to minimize the new APF injection currents while satisfying harmonic standards. Genetic algorithm is proposed for these two optimization p...
