Structural state-based frame synchronous compensation
In this paper we present improvements of a framesynchronous noise compensation algorithm that uses Stochastic Matching approach to cope with time-varying unknown noise. We propose to estimate a hierarchical mapping function in parallel with Viterbi alignment. The structure of the transformation tree is build from the states of acoustical models. The objective of this hierarchical transformation...
متن کاملNeural-Networks and Synchronous Reference Frame Applied in the Harmonic Compensation with a Three-Phase Parallel Active Power Filter
This paper presents an alternative method based on artificial neural network, which is used to obtain the reference currents for harmonic current suppression and reactive power compensation in a shunt active power filter applied to three-phase four-wire system. The neural network consists of a multilayer perceptron, which is trained to estimate the peak amplitude of the load fundamental compone...
متن کاملOn-line frame-synchronous compensation of non-stationary noise
We present a frame-synchronous noise compensation algorithm that uses Stochastic Matching approach to cope with time-varying unknown noise. This method proposes to estimate simple mapping function in parallel with Viterbi alignment. The technique is entirely general since no assumption is made on the nature, level and variation of noise. Our algorithm is evaluated on the VODIS database recorded...

متن کاملSynchronous Reference Frame Detection and Hysteresis Control for Active Power Filters
Power Quality means maintaining purely sinusoidal current wave form in phase with a purely sinusoidal voltage wave form throughout in a power system. Due to intensive use of power converters and other non linear loads in industries, an increasing deterioration of the power system voltage and current waveforms has been observed. The most important cause for degrading power quality are harmonic d...
