N-UNIT AUTONOMOUS POWER PLANT Russian patent published in 2023 - IPC H02J3/34 

FIELD: power engineering.

SUBSTANCE: power plant contains first electric unit (hereinafter – EU) (1) with a variable frequency, which has: ICE (2), synchronous generator (3), rotational speed regulator (hereinafter – RSR) (4) of ICE shaft, unit (5) for generating an economical rotational speed, generator excitation unit (6), controllable rectifier (7), voltage stabilization unit (8), smoothing accumulator filter (9), power sensor (10), autonomous voltage invertor (11), frequency point adjuster (12), transformer (13). Electric units from the second (14-2) to (14-(N-1))th have ICE (15) with a constant rotational speed of a shaft, RSR (16), synchronous generator (17) with excitation unit (18), active power sensor (19), and switcher (20). Power sensor (10) and active power sensor (19) have digital outputs. In addition, the circuit contains synchronizer (21), unit (22) for automatic control of the second EU, numerical comparator (23), logical element AND (24), setting register (25), subtractor (26), load (27), and plant power sensor (28). EU have same nominal capacities.

EFFECT: increase in power of a power plant, while saving a mode of the minimum specific fuel flow rate.
