METHOD FOR REMOTE CHANNELLESS CONTROL OF POWER REDUCTION AND DISCONNECTION OF GENERATION SOURCE CONNECTED TO ELECTRICAL NETWORK POWERED BY TWO-TRANSFORMER SUBSTATION Russian patent published in 2021 - IPC H02J13/00 H02J9/04 

Abstract RU 2755409 C1

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to the automation of electrical networks. The effect is achieved by recording the inrush current in the outgoing lines having electrical connections with the network section to which the generation source is connected, comparing the current inrush value recorded in one of the monitored outgoing lines with the current value corresponding to the load current of the first network section fed in normal mode from the source of generation, the inrush current corresponding to the increase in the load current of the second section of the network, powered in normal mode from the source of generation, is recorded, in the same controlled line.

EFFECT: expanding the functionality of the method by obtaining, with the help of remote channelless control, information about reducing the power and disconnecting the generation source connected to an electrical network powered by a two-transformer substation.
