Desenvolvimento de um sistema para aquisição e processamento de sinais utilizando a plataforma TivaWareTM para aplicações em Smart Grid

Abstract

Amid a scenario, that contrasts the increasing demand for electricity, and decreased ability to generation from conventional sources, which is creating serious problems for the energy sector, the concept of smart grids popularizes up and presented as an alternative to, among other possibilities, minimize the effects of power outages in the design of distributed generation from alternative sources. In order for alternatives to that end, it will develop a data acquisition system, low cost and high performance for applications in smart grids, which facilitates monitoring of electricity in real time, where the user can manage their own control avoiding waste and consequently saving. The system will be developed based on the standards of ANEEL (Brazilian Electricity Regulatory Agency), body responsible for determining the minimum parameters a measuring equipment must possess. The data acquisition system showed results with a high degree of agreement when compared with the reference instrument, the fluke 434/435. A response curve of voltage and current, showing the system behavior compared to other instruments of measurement was introduced. Still, it is objective of the work that the signs Conditioning Unit can be adapted for multiple microprocessor platforms, using simple settings, without the need for hardware reconfiguration. This fact has been proven to be used with Black BeagleBone with satisfactory results.
