Platform prototype development Synchrophasorial measurement

Abstract

Monitoring Systems act decisively in any process, maintaining and operability of the equipment. This is valid for the electrical system that, in particular in Brazil, require a complex analysis and control for stable operation, given its territorial extension, demanding a large number of points and monitoring units. In this context, the equipment that has been gaining the market for providing synchronized quantities along the long points of the System is the Phasor measurement unit (PMU). This complex equipment is capable of providing the system operator with values snapshots, stresses, phase angles, frequency and frequency variation rateSynchronised with a satellite signal in Universal time coordinates (UniversalTime Coordinade-UTC) with low latency of sending data, in counter-start, in the general, the cost of high investment. Due to this high cost distribution systemsare not monitored in its entirety. With the installation of PMU's at various pointsof the low-voltage system would add to the distribution operator a large amount of data that would assist in various purposes, from monitoring the profile to the of tensions to studies and adjustment of the mathematical models of the conditions of the electrical system during a pre-or post-absence of Eneriga. However, combining the high cost of acquisition andInstallation of PMU's to a distribution system is an arduous task. This the main objective of this work is to offer an affordable cost-effective equipment for the systems requiring a remarkable amount of measurement units. (AU)
