“…For identification of disturbing current the instantaneous reactive power method has been used in this paper. For controlling the output currents of the converter, to follow the reference currents, hysteresis current controller have been used in [13][14][15].The implementation of hysteresis current controller is simple and its performance is also excellent. However, this controller suffers from drawbacks.…”

This research deals with design of three-phase hybrid active power filter to reduce the current distortions caused by non-linear loads. The Instantaneous Active and Reactive Power Method (p-q) is used to perform the identification of disturbing currents. The p-q algorithm generates the reference compensation current signal, while this generated reference compensation current signal is exactly followed by the output current of the voltage source converter. Fuzzy logic controller for three-phase hybrid active power filter is used to generate the switching signals in order to control the output currents of voltage source converter. Simulation results showed that the hybrid active power filter can compensate the harmonic currents effectively and improve power quality.

“…The most significant issues for a single-phase system are -reactive power and current harmonics, which are the major concerns for a modern power distribution system, since these issues play a vital role in giving rise to the other power quality problems. A single-phase APF can be installed at low-and medium-power applications, such as triac-based controllers for heating applications, uninterruptible power supplies, AC voltage regulators, switch mode power supplies, electronic fluorescent lamp ballasts, electric arc furnaces [1][2][3], electric traction [4,5] and so on. Three or more single-phase APF modules can also used in multilevel or multicell configurations for three-phase medium-power applications, such as motor drive applications [6,7].…”

The single-phase p-q theory for the purpose of active power filtering in the case of single-phase loads is dealt with here. A simple modification is proposed to develop a generalised single-phase p-q theory that can be utilised under the condition of distorted utility voltage. A systematic study is presented by realising both direct and indirect current control techniques. The simulation as well as the digital signal processor (DSP) (DS1104 of dSPACE) based experimental results are discussed. The developed single-phase shunt active power filter (APF) prototype is tested under different operating conditions with different loads to evaluate the full capabilities of the proposed generalised theory for practical uses. The shunt APF reduces the source current total harmonics distortion (THD) from 27.2 to 3.4% under a distorted supply voltage with a THD of 16.2%.

“…At the beginning, an FFT (Fast Fourier Transform) method had been proposed, which however had the drawback that more than two cycles of the fundamental waveform were needed for the harmonic detection: the first for data acquisition and the second for their processing. Another approach was based on the instantaneous p-q theory, both in the three-phase [4] and single-phase version [5]: this approach in the three-phase version wants the load to be balanced and in any case requires at least one cycle of the fundamental to compute the average instantaneous power. The synchronous d-q reference frame theory has been also adopted, but it does not permit any reactive power compensation.…”

This paper presents a single-phase shunt active power filter for current harmonic compensation based on neural filtering. The shunt active filter, realized by a current controlled inverter, has been used to compensate a nonlinear current load by receiving its reference from a neural adaptive notch filter. This is a recursive notch filter for the fundamental grid frequency (50 Hz) and is based on the use of a linear adaptive neuron (ADALINE). In this way the inverter creates a current equal in amplitude and opposite in sign to the load harmonic current, thus creating an almost sinusoidal grid current. The methodology has been applied in numerical simulations and experimentally on a properly devised test setup. With this regard, a reduced scale electrical grid has been built and used for assessing this methodology.
