Reconfigurable instrument for power quality monitoring in 3-phase power systems

Abstract: From voltage and current signals it is possible to obtain relevant information regarding 3-phase power supply features like signal amplitude, frequency, harmonic contents, phase, among others. This information is useful to solve problems like power quality monitoring, diagnosis of electrical machines, electric systems protection, and control. This work presents preliminary results on the design of a reconfigurable tool for electric parameter monitoring in 3-phase power systems based on low-cost field programma… Show more

“…The method of symmetrical components estimation is used to analyze and quantify the voltage/current unbalance [1,2,[13][14][15]; for this, it is required the surveillance of the 3-phase voltage or current signals, at the same time. The zero, positive, and negative symmetrical components, U 0 , U pos , and U neg , respectively, can be obtained from the three-phase system fundamental components U a , U b , and U c written in the form of complex-voltage phasors, as follows:…”

“…On the other hand, some of the above mentioned works are implemented on personal computer (PC) which can compromise the online operation; even more when the three-phase voltage and current signals have to be analyzed at the same time. A promising technology to satisfy the realtime and online operation requirements is the field programmable gate array (FPGA) due to its parallelism and reconfigurability as has been demonstrated in many industrial applications [10][11][12][13].…”
