DEVICE TO STABILISE VOLTAGE AND FREQUENCY OF WIND-ELECTRIC PLANT Russian patent published in 2013 - IPC H02P9/06 

FIELD: electricity.

SUBSTANCE: voltage stabilisation system (10) comprises a unit of excitation capacitors (11), a rectifier (12), a transistor (13), a pulse amplifier (14), a transformer-rectifier unit (17). Inlets of the transformer-rectifier unit (17) are inlets of the voltage stabilisation system (10), the outlet of the transformer-rectifier unit (17) is connected with the first inlet of the pulse shaper (15), and its second inlet is connected with the outlet of the clock oscillator (16), the outlet of the pulse shaper (15) via the pulse amplifier (14) is connected to control electrodes of the transistor (13), an emitter-collector transition of which is connected to the inlet of the rectifier unit (12), the outlet of the rectifier unit (12) is connected to the outlet of the asynchronous generator (5) via the unit of excitation capacitors (11). The frequency stabilisation system (9) comprises a transistor (21), a pulse generator (18), a transformer-rectifier unit (20) and a pulse amplifier (19).

EFFECT: increased reliability of operation and improvement of weight and dimension parameters, an asynchronous generator is a single-speed asynchronous generator with a short-circuited rotor, stator windings of which are connected to a load and systems of voltage and frequency stabilisation.
