METHOD OF EMERGENCY LOAD LIMITATION IN POWER DISTRIBUTION NETWORK Russian patent published in 2015 - IPC H02J13/00 H02H3/08 

FIELD: electricity.

SUBSTANCE: in case of emergency in the network pulse-time coded commands for switching off are set for non-essential consumers, the station operating in emergency mode to the isolated network section is selected, in switchgear with voltage 10(6)-20 kV at the transmitting end of the line passing from the selected station in case of emergency power circuit breakers are switched off for a short moment and switched on and power supply interruptions of different fixed duration are created at actuators related to this line of power consumers, in switchgear of a lower voltage level these interruptions are received as pulse-time coded commands and upon their identification power switches of non-essential consumers are switched off on a selective basis.

EFFECT: improved reliability of power supply for essential consumers.
