This paper deals with thermal behavior and life expectancy analysis of three-phase induction motors under non-sinusoidal supply, emphasizing the random nature voltage variations due the dynamic of electrical power systems. The necessity to realize the statistical/probabilistic procedure to analyze power quality problems and their impact on the electrical equipment is due mainly to its variable nature...
This paper presents a methodology aimed at extracting features to obtain information that will highlight disturbances related to the field of power quality. Due to the concept of smart grids, it is clear that the classification of the disturbances should be undertaken using smart meters, so that a large amount of data corresponding to the voltage and current waveforms are not exchanged using the communication...
This paper proposes to apply an instantaneous sequence estimation technique to enhance the control systems applied in distributed generation. It relies on a recursive least-square estimation of the αβ voltage components which are directly linked to the sequence components. The method was originally proposed to serve a dynamic voltage restorer controller. Here, this technique has been expanded to improve...
The main objective of this paper is to present an approach based on Fuzzy Inference Systems for the determination of harmonic contribution at Points of Common Coupling (PCC), i.e., it is intended to determine the harmonic distortion responsibilities between consumer and utility at these points. For this purpose, the proposed approach uses some features extracted from the voltages and currents measured...
This paper proposes an analysis of the impact of five different synchronization methods on the performance of the compensation currents generated by shunt active filters. The discrete model of shunt active filter is presented considering its implementation in a DSP. Furthermore, two control loops are used to perform the control, an external loop to regulate dc-link voltage that uses a servo system...
