FIELD: electricity. ^ SUBSTANCE: invention is related to electrical engineering. Device contains power circuit that contains three power units, which are joined together with their three-phase inlets, output filter, unit of current transformers, master generator, three control units, measurer of voltage deviation, magnetisation controller, unit of cosine synchronisation, at that every of control units contains adder, the first and second shapers of control signals, generator of curve type, besides, transformer with rotary magnet field contains secondary three-phase windings, primary main and additional windings and condenser, also contains control winding of control throttle, transformer-rectifier unit, and power units contain three couples of inverse-parallel connected thyristors each, inlet of every couple is connected to outputs of generator accordingly, and outlets of three couples of each power units of thyristors are combined and represent single-phase inlet of power unit. ^ EFFECT: provision of voltage and frequency stabilisation in case of oscillations and unsymmetry of power generator voltage. ^ 1 dwg |
