FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering. Device for automatic regulation and voltage stabilization of asynchronous generator contains asynchronous generator 1 with output terminals 2, 3, 4 for load connection, to which excitation capacitors 5 are permanently connected. Three single-type single-phase automatic excitation regulators 6, 7, 8, each of which has k (k – integer, k>1) of parallel connected control elements 9, consisting of series connection of capacitor 10 and bidirectional semiconductor switch 11. Automatic voltage control unit 12 comprising series-connected single-phase voltage measuring transformer 13, single-phase bridge rectifier 14, algebraic adder 15, analogue-to-digital converter 16, control stage selection unit 17, and control pulse generator 18 of bidirectional semiconductor switches 11.
EFFECT: technical result consists in improvement of output voltage stabilization process efficiency with simultaneous reduction of power losses.
