Smart grid: monitoring the quality of electric power

The issues of monitoring the normalized parameters of electricity, in smart grid networks, as a means of ensuring control of the quality of electricity, are considered. In the context of constantly growing consumption of electrical energy, the most important task is its rational distribution and use. State-of-the-art prototypes of intelligent power distribution networks include means of controlling power distribution and consumption processes to ensure that these processes comply with applicable regulations. The purpose of our study is to create a monitoring device for normalized power quality parameters, such as voltage, signal shape, harmonic coefficient, with the possibility of detecting deviations of these parameters from the norm, with the possibility of transmitting the results obtained via infocommunication networks. The developed device allows collecting, analyzing and transmitting data on power quality indicators in the distribution electrical network, with their further use in order to manage energy supply and energy consumption in smart power supply systems, and improve the energy efficiency of power supply systems through the introduction of smart grid technologies. The device can be integrated into energy systems based on the smart grid concept, which are a single energy-information complex, as part of a situation assessment system and emergency automation.
