An electronic device with wi-fi communication for consumption data acquisition and power quality
IoT device; Power quality; Embedded systems
With the increase of usage of smart devices and the popularization of the Internet of Things (IoT), new monitoring applications through sensors have emerged in different fields, whether in industry or a household environment. In the electric power sector, for instance, there is a need to acquire and transmit data related to power consumption (output, current, and voltage). Currently, there are still large consumers who do not monitor the individual consumption of their smaller units and only have access to an overview of consumption, which makes it harder to identify outbreaks of energy waste. In the specific case of UFRN, to analyze the energy consumption and the power quality, a portable device is installed at the energy substation, over some time, and collect the data that will be analyzed later. With this in mind, this work proposes the creation of an IoT device: an electronic board with wireless communication. The card, in addition to performing the acquisition and transmission of the energy consumption data, also sends data related to power quality, such as harmonic distortion data, identification of short-term voltage drop or increase, measurement of phase angles, power factor, and frequency of each phase. The board aims to become an option for the creation of Smart Grids, and shortly become a contributor to the reduction of energy costs on the university.
