FIELD: electrical equipment.
SUBSTANCE: use: in the field of electrical engineering and power engineering. According to method voltages are monitored on reserved line, in case of short circuit in section of reserved line its automatic switching is performed, and in case of unsuccessful repeated switching on results of voltage measurement on sections of reserved line its damaged section is determined, disabling appropriate partitioning switch installed in reserved line, and performing network automatic reserve of power district, wherein voltage and frequency measurements are made in a power area with sources of distributed generation, the damaged section of the reserved line is determined based on voltage monitoring and position of the partitioning switches, preliminary simulation of functioning of power area in normal and emergency modes on a reserved line is carried out, according to results of which options are determined for automatic transfer of reserve, simulation data are recorded in the memory of the operational information complex of the power district, setting the starting elements of automatic input of voltage and frequency reserve and a signal is sent to a switch, which enables operation of the network automatic input of the reserve when the firing elements actuate as to voltage and frequency.
EFFECT: wider field of application and higher reliability of uninterrupted power supply.
