FIELD: electrical power engineering. SUBSTANCE: decrease of active power of high-voltage power line having high charging capacitance causes increase of voltage across buses of receiving energy system which augments maximum permissible value of transfer over another controlled high-voltage line adjoining to buses of receiving power system having lower charging capacitance. In this case maximum permissible increment of transfer of controlled high-voltage power line dependent on decrease of load over long-length power lines is determined and setting of power transfer in controlled power line is increased by value of increment of power transfer. EFFECT: improved reliability of control over power transfers. 1 dwg
