This paper presents a sensorless control strategy for pulsewidth modulated active filters. The complete solution uses only two current sensors, which are located in the grid interface. The compensation is performed by the imposition of sinusoidal current references in the grid, and does not require algorithms for disturbance estimation. The virtual flux concept for grid synchronization and multiple...
This paper proposes an analysis of the impact of five different synchronization methods on the performance of the compensation currents generated by shunt active filters. The discrete model of shunt active filter is presented considering its implementation in a DSP. Furthermore, two control loops are used to perform the control, an external loop to regulate dc-link voltage that uses a servo system...
This paper briefly reviews the adaptive notch filter (ANF) based synchronization techniques for single and three-phase converter-interfaced distributed generation (DG) systems. These techniques are compared in terms of their capability in tracking the grid frequency variations in the presence of low order harmonics and unbalance conditions. The techniques introduced in this paper are applicable for...
This paper briefly reviews the synchronization techniques for three-phase converter-interfaced distributed generation (DG) systems. These techniques are compared in terms of their capability in tracking the grid frequency variations in the presence of low order harmonics and unbalance conditions. Moreover, this paper introduces a new three-phase adaptive notch filtering (ANF) synchronization technique...
This paper briefly reviews the synchronization techniques for single-phase converter-interfaced distributed generation (DG) systems. These techniques are compared in terms of their capability in tracking frequency variations, and the phase angle of the grid signal in the presence of low order harmonic. The techniques introduced in this paper are applicable for a wide range of equipment like converter-interfaced...
