FIELD: electricity.
SUBSTANCE: in method of control the stator winding of the asynchronous generator driven by wind, hydraulic or thermal engine, is connected in parallel to the grid via the secondary windings of the booster transformer, which, by means of transformer transformation ratio adjustment, maintains voltage at the stator of the asynchronous generator within the range of (93-100)% from the rated voltage in function of active power of asynchronous generator. The booster transformer transformation ratio is controlled by switching taps at the primary winding by optoelectronic AC relays, which are switched in active power function of the asynchronous generator.
EFFECT: improved power parametres.
