Modern power system networks use active power filters for compensation of harmonic currents generated by non linear loads. In this paper a new method for generating reference currents for harmonic and reactive power compensation is proposed. The proposed method has the advantage that it generates the reference currents irrespective of the supply voltage and load conditions. So the source has to...

Blind source separation usually obtains limited performance on real and polyphonic music signals. To overcome these limitations, it is common to rely on prior knowledge under the form of side information as in Informed Source Separation or on machine learning paradigms applied on a training database. In the context of source separation based on factorization models such as the Non-negative Matr...

With the introduction of more non-linear loads, e.g., compact fluorescent lamps, electric vehicles, photovoltaics, etc., the need to determine the harmonic impact of the residential load is rising, illustrated by the many studies performed on their harmonic impact. Traditionally, these studies are performed for a single new device and single penetration level, neglecting the harmonic interactio...

This Project deals with an Embedded Z-source inverter to control the three phase induction motor. The Z-source inverters are recent topological options for buck–boost energy conversion with a number of possible voltage and current-type circuitries. The common advantage of Z-source inverter and Embedded Z-source inverter is the inclusion of an LC impedance network, placed between the dc input so...

Clear first harmonic emissions of Saturn Kilometric Radiation are discovered during the Cassini Grand Finale orbits. Both ordinary (O) and extraordinary (X) mode fundamental accompanied by X harmonics observed. Analysis shows that frequency ratio between is 2.01 ± 0.08, display weaker intensities than fundamental, 30–40 dB for X-X (fundamental-harmonic) type 10–30 O-X harmonic. The intensity re...

Electron beams are strongly microbunched near the high-gain free-electron laser (FEL) saturation with a rich harmonic content in the beam current. While the coherent harmonic emission is possible in a planar undulator, the thirdharmonic radiation typically dominates with about 1% of the fundamental power at saturation. In this paper, we discuss the second-harmonic radiation in the Linac Coheren...

This paper presents a new methodology to estimate harmonic sources in a distribution network, based on measurements of limited number of given buses. The algorithm utilizes independent component analysis (ICA), a method of solving blind source separation theory. In this method, pseudo impedance matrix of distribution network is estimated. The location of harmonic sources will be identified by e...

In this paper, we propose a novel approach to harmonicpercussive sound separation (HPSS) using Non-negative Matrix Factorization (NMF) with sparsity and harmonicity constraints. Conventional HPSS methods have focused on temporal continuity of harmonic components and spectral continuity of percussive components. However, it may not be appropriate to use them to separate time-varying harmonic sig...
