POWER UNIT WITH CONTROLLED REACTIVE POWER, MAGNITUDE AND PHASE OF VOLTAGE Russian patent published in 2016 - IPC H02P9/14 H02P9/30 H02J3/18 

FIELD: electronic equipment.

SUBSTANCE: invention relates to electrical engineering and can be used for adjustment of voltage and reactive power of power plant generators. Device consists of a synchronous generator with non-adjustable excitation system; to its outputs there are connected beginnings of the service transformer primary windings, ends of which are outputs of the power unit, while the service transformer secondary windings are connected to outputs of alternating voltage of the first voltage converter. Connected to outputs of the power unit via a transformer are AC outputs of the second voltage converter, DC outputs of which are connected with unipolar DC voltage outputs of the first converter. Outputs of signals of the automatic controller of reactive power, magnitude and phase voltage of the power unit are connected to corresponding inputs of control systems of voltage converters.

EFFECT: technical result consists in improvement of reliability of the power unit, increase in the value of active power, issued into the network by the synchronous generator of the power unit, and faster operation during adjustment of the power plant voltage and reactive power.
