ELECTRIC POWER SUPPLY SYSTEM Russian patent published in 2021 - IPC H02J3/46 H02J9/06 

FIELD: electrical engineering.

SUBSTANCE: present invention relates to the field of electrical engineering, in particular, to systems for electric network power supply and electric power distribution, interconnected control of electric power supply tools, e.g., diesel electric units. The electric power supply system is made of at least one electric power plant 1 containing an electric generator set 2, an external network input 3, a power offtake system 4, a synchronisation switching bus 5, a control system 6, and a control communication bus 7. The control communication bus 7 serves for connecting the control system 6 to the electric generator set 2, external network input 3 and power offtake system 4. In turn, the power offtake system 4 is intended for connecting the electric generator set 2 and/or external network input 3 via the synchronisation switching bus 5 to the synchronisation switching buses 5 of the adjacent electric power plants 1 and to consumers 8. The electric power plant 1 is therein additionally equipped with a second control communication bus 9 and a software module 10 for controlling the electric power supply system, equipped with two input-outputs 11 and 12. The input-output 11 is therein connected to the control communication bus 7, and the input-output 12 via the second control communication bus 9 is intended for connecting to the input-outputs 12 of the software modules 10 for controlling the electric power supply system of the adjacent electric power plants 1 via the second control communication buses 9 thereof.

EFFECT: increase in the reliability of the electric power supply system.
