“…To improve the power quality, traditional solutions like passive LC filters have been widely used for a long time [1]. However, bulk passive components, series and parallel resonance and fixed compensation characteristics for fixed values of L and C are the main drawbacks of passive LC filters.…”

“…However, bulk passive components, series and parallel resonance and fixed compensation characteristics for fixed values of L and C are the main drawbacks of passive LC filters. In order to overcome all these problems simultaneously, various active power filters (APFs) have been developed in recent years [1,2] due to the development in power converters and digital signal processors. The objective of these APFs is to reduce the voltage and current harmonic distortion [3].…”

rect power control of shunt active filter using high selectivity filter (HSF) under distorted or unbalanced conditions. Electric Power Systems Research, Elsevier, 2014, 108, pp.113-123. <10.1016/j.epsr.2013.006>. AbstractThis paper describes the design of a new configuration of direct power control (DPC) based on high selectivity filters (HSF) to achieve near-sinusoidal source current waveforms under different source voltage conditions. The proposed method uses the high selectivity filters instead of the classical extraction filters (low pass filters). The basic idea of the proposed DPC is to choose the best inverter voltage vector in order to minimize instantaneous active and reactive power errors using two hysteresis comparators. Their outputs associated with a switching table, control the active and reactive powers by selecting the optimal switching states of the inverter. Simulation results have proved excellent performance, and verify the validity of the proposed DPC scheme, which is much better than conventional DPC using low pass filters.

“…Their first applications were focused to compensate the harmonic components of the load current. Later, they were developed to compensate wider targets like the reactive and unbalance components, receiving then the denomination of Active Power Line Conditioner, APLC [1]. Although, the emphasis must be focused in the Unified Power Quality Conditioners, UPQC [2][3][4][5][6][7][8], which integrate in one module a combination of series and parallel APFs.…”

Abstract. This paper presents the obtained experimental results with a single-phase experimental prototype of a Load Compensation Active Conditioner, sLCAC. The sLCAC is composed by a series -parallel combination of active power filters, and its main objective is the global conditioning of a load against harmonic distortion. On the one hand, to isolate the load voltage v L from the harmonics in the supply voltage v S , as well as to regulate it to the nominal value. On the other hand, to improve the supply current i S , compensating the harmonic and reactive components of the load current i L . An experimental prototype has been implemented, and the obtained results are presented to support the performance of the proposed design.

“…Traditional active power filters (APFs) have been proposed [1], [2], [3] for location adjacent to major non-linear loads to provide equal but opposite harmonic currents and thus prevent the flow of harmonic currents into the power network. There are two problems with this approach.…”

This paper investigates the use of ancillary services from inverter-interfaced distributed generators (DGs) to achieve harmonic mitigation across a network. The approach is to include the functionality of a resistive active power filter (R-APF) within several DGs. The R-APF provides adjustable damping at harmonic frequencies. In a realistic network, which has feeder sections of different characteristic impedances, it is impractical to damp with precisely that resistance. Instead, feeders are split into harmonic sections based on the standing waves of the highest order harmonic and DG ancillary services are called up for each section. Coordination of services from each DG is arranged through adaptation of the harmonic resistance according to target THD levels. The primary purpose of each DG is the supply of real power and this is respected through a further aspect of the resistance adaptation which reduces the harmonic duty of an individual DG if it approaches the apparent power rating of the inverter. The harmonic VA required of the inverter is dependent on both the chosen harmonic resistance and the harmonic voltage component present at the connection bus. The system is demonstrated through a simulation of an irregular feeder using Simulink and PLECS.
