EXCITATION CONTROL SYSTEM OF SYNCHRONOUS GENERATOR WITH EXTERNAL FORCING Russian patent published in 2020 - IPC H02P9/10 H02P9/14 H02P9/30 

FIELD: electrical engineering.

SUBSTANCE: excitation system includes synchronous generator (1) having armature winding (2) and inductor winding (3). Besides, it includes rectifiers 4 and 15, summing transformer (5) with windings (6), (7), (8) and (9) and voltage corrector (10). System also comprises external DC sources (11) and (43), electronic switches (12), (46) and (47), current transformer (13), shunt (14), analogue-to-digital converter (16), memory registers (17), (18), (44) and (45). Besides, the system includes pulse distributor (19), pulse generator (20) of stable frequency, subtractor (21), decoder (22), load terminals (23) and (24), RS-triggers (25) and (41), shapers (26) and (38) of short pulses. Besides, it comprises logic element OR (27), RUN bus (28), shaper-limiter (29), inverters (30) and (42), logic elements AND (31), (32), (33), (34) and (35), numerical comparators (36) and (37), delay elements (39) and (40), and RESET bus (48).

EFFECT: technical result consists in expansion of functional capabilities due to provision of forcing during throwing and load release.
