INDUCTION GENERATOR VOLTAGE REGULATION DEVICE Russian patent published in 2005 - IPC

FIELD: electrical engineering; windmill-electric power plants, very small hydroelectric plants, and off-line power supplies.

SUBSTANCE: proposed voltage regulation device has unit 2 of three single-phase step-up transformers whose primary windings 3 are connected to output of three-phase generator 1 and first group of secondary windings 4, 5, and 6, to field capacitor 10; second group of secondary windings 7, 8, and 9 are connected through additional capacitor 11 to thyristors 12 and 13 interconnected in parallel opposition; inputs of device control system 22 are connected to outputs of induction generator 1 and to leads of field capacitor 10, and system output is connected to control inputs of thyristors 12 and 13; control system incorporates transformer-rectifier unit 14, pulse shaper 15, sawtooth voltage generator 16, voltage polarity sensor 17, AND gates 18, 19, and pulse amplifiers 20, 21.

EFFECT: reduced mass of field capacitors, enhanced reliability of device.
