Currently, due to the global shortage of energy carriers the goal of more efficient use of the existing power sources and transmission lines is getting increasingly more important. At the same time, however, there is a known contradiction. In order to enhance the efficiency, we use advanced industrial electronics, rectifiers, frequency transducers, inverters, etc. This increases the efficiency of the technological plants, but at the same time the supply voltage suffers from an elevated level of harmonic components in the network. As is well known, nonlinear load generates harmonic components, resulting in a change of delivered power characteristics, namely indicators degrades the supplied power quality. In turn, the deterioration of the power quality leads to its overrun. In this regard, the problem of monitoring and reducing the harmonic components is relevant. Timely and accurate measurements based on data recorders vector quantities with high resolution, offers the prospect of continuous monitoring of the quality of power supply. The paper presents a system of continuous power quality monitoring. The system makes it possible to detect a source and a level of nonlinear distortions (harmonics), estimate the harmonic energy cost and control power quality parameters. Index Terms--Power quality, voltage and current harmonics, distributed monitoring of power quality, electric power systems, smart grids.
