this paper presents a new control method for a three-phase four-wire unified power quality conditioner (upqc) to deal with the problems of power quality under distortional and unbalanced load conditions. the proposed control approach is the combination of instantaneous power theory and synchronous reference frame (srf) theory which is optimized by using a self-tuning filter (stf) and without us...
Sound source separation has become a popular research topic in computer audition due to its wide range of applications in the analysis and manipulation of audio data. Applications of audio source separation include music information retrieval, automatic transcription of music, and sampling of musical sounds for electronic music composition amongst many others. Through this paper, different algo...
This paper represents the simulation of Shunt Active Power Filter(SAPF) based on p-q theory and using hysteresis current control to obtain the gating signals for three phase ac-dc converter. The proposed active power filter is employed to reduce the current Total Harmonic Distortion (THD) drawn by the non-linear load and compensate the reactive power. The PI controller is employed to reduce the...
Abstract: Based on the fast kernel entropy optimization independent component analysis and the minimum conditional entropy, this paper proposes a harmonic source localization method which aims at accurately estimating harmonic currents and identifying harmonic sources. The injected harmonic currents are estimated by the fast kernel entropy optimization independent component analysis (FKEO-ICA) ...
A constrained iterative method for harmonic source parameter estimation is proposed based on an EM algorithm with an intent for harmonic source separation. The problem of coinciding partials and interference among them in general is mitigated by the constraints on the “weak” partials on the stronger ones of the same harmonic source. A useful scheme to determine the weakness of a partial is prop...
