The paper introduces a new approach, based on the computer-aided monitoring of the motor instantaneous current space phasor (ICSP), for diagnosing the occurrence of inter-turn short circuits in the stator windings of operating three-phase induction motors. The proposed diagnostic technique generates the motor ICSP, whose modulus through time ripple increases with the severity of the fault and whose...
This paper presents a method of classification of power quality disturbances using Wavelet transforms combined with artificial neural network. Multi-resolution Wavelet analysis has been used as feature extractor, with different mothers Wavelet. Result comparison has been made in two levels: first, using different wavelet mothers, to determinate if the classification performance is better with a specific...
In 2006, at University Politehnica of Bucharest, in the framework of the European demonstration project PV-enlargement, and of the Romanian project ldquoPV gridrdquo, a rooftop grid-connected photovoltaic power generation system of 30 kWp has been installed. This is a double array PV system containing two kinds of silicon modules: crystalline and amorphous. The installed power of crystalline modules...
