Developing of functioning algorithm of information-control system for phase-shifting devices in power lines

The article is devoted todevelopment of afunctioning algorithm of the control systemof phase-shifting devices in double-circuit overhead power lines, as well as to the formulation of the main tasks of this system. Based on these, functional schemes for controllingphase-shifting devices were developed.The developed system will allow, through the use of phase-shifting transformers, which belong to the flexible alternating currenttransmission system (FACTS)technology, to change the value of phase shift angle of the voltage and current vectors of one circuit relative to anotherthat.Thiswill lead to a change in the value of the wave impedance of double-circuit lines, due to the emergence of new electromagnetic connections between the conductors of the two circuits. The main task of the developed system is to support the operation of power lines in the matched load mode, when the value of the wave imped-anceis equal to the value of the load impedance. It follows from the analysis that this mode provides the lowest losses in the trans-mission of electricity through power lines.The implementation of this control system is planned by using the Internet of Things in-formation technology, that is, the formation of a wireless connection between the main elements of the system for data transmission.The developed system can be attributed to information systems, as well as the current concept of SmartGrid.Thus, a method has been proposed to increase efficiency by reducing losses during the transmission of electricity through double-circuit power lines through the use of the concept of SmartGrid.
