This paper presents detailed modeling and simulation of a compensator for Load balancing and harmonics Compensation based on a five-level cascaded H-bridge multilevel voltage source inverter. This type of compensator, which is installed in parallel with the load, is usually referred to as the shunt active power filters (APF). Nowadays use of high voltage non-linear loads are widely used in indu...

This paper presents a survey on key issue, challenges and opportunities of power quality problems (PQ) such as transients, instantaneous (interruption, swell & sag), long duration variations (interruption, under voltage, over voltage), harmonics, voltage unbalance, voltage fluctuation, power frequency variations, power factor of system, and waveform distortion such as current and voltage in the...

This paper presents an efficient harmonic detection for real-time generation of the reference current fed to a shunt active power filter using ADALINE neural network. proposed method is single layer with 101 nodes generating coefficients referred as weights model. It effectively overcomes drawback technology, which instantaneous theory (PQ). The was implemented on TMS320F28335 DSP board and tes...

In this paper, a proposed efficient solution for an important power quality problem focused on harmonic distortion in the source current is introduced by using Shunt Active Power Filter (SAPF) controlled sinusoidal control strategy which based instantaneous active and reactive theory (Sinusoidal PQ-theory). As part of controller, there PI-Controller enhances APF controller performance when tuni...

− This paper presents an analysis of Akagi’s pq theory for active filtering under really non-sinusoidal voltage. So, it is ascertained that compensating of alternative parts of instantaneous active and reactive powers establishes a sinusoidal current in the parallel active filter. But this is true under sinusoidal voltage only. The mathematical demonstration is found and it is verified on few p...

A form of stochastic perturbation theory is described, where the representative stochastic fields are generated instantaneously rather than through a Markov process. The correctness of the procedure is established to all orders of the expansion and for a wide class of field theories that includes all common formulations of lattice QCD.
