As a large and complex dynamic and interconnected system, the Brazilian electrical grid presents a challenge to meet reliability and robustness criteria, and the concept of smart grid shows a solution to meet these criteria. Smart grid is a modern electrical grid with resources like communication and advanced automatic control, but before the automation from the traditional electrical grid to smart grid can be made, it is necessary an end-to-end system monitoring, now made by SCADA systems. However, the monitoring through these systems presents delays in the order of seconds, becoming impossible to know the state of the electrical grid in real time, motivating the study of alternative solutions for real-time monitoring. One of the solutions found is the synchronized phasor measurement unit, which performs a real-time monitoring of distribution grids, through phasor estimation, synchronized with GPS pulse. The collected data is encapsulated in data frames, as written in the IEEE C37.118.2 - 2011 norm, and sent to a data concentrator through Internet connection for storage and processing. This work presents an enhancement of features of a synchronized phasor measurement unit developed in the Electrical Engineering Post-Graduate Program (EEPGP) of Federal Technological University of Paraná, Pato Branco. The data collected by the measurement unit developed in the EEPGP is sent to a data concentrator through wired Internet connection. This work aims to add the feature of sending data collected by the measurement unit to the data concentrator through Wi-Fi, as well as migrating the source code of the embedded system used in the measurement unit to a newer one, with more features and better processing power. |
