THREE-PHASE STATIC POWER COMPENSATOR Russian patent published in 2021 - IPC H02J3/16 

FIELD: electrical networks.

SUBSTANCE: invention relates to the field of electrical networks and can be used in lateral compensation devices for the purpose of controlling the power transmitted through power lines. The subject of the invention is a three-phase static power compensator connected to the phase terminals of a three-phase AC sinusoidal voltage network, one or more phases of which contain a series connection of the reactive element and the output terminals of the AC sinusoidal voltage regulator, while the input terminals of the AC sinusoidal voltage regulator are connected to the phase terminals of the static compensator power. The control system unit provides control of the variable sinusoidal voltage regulators in the phases of the static power compensator and ensures the formation of the required voltages on their reactive elements. One or several phases of the static power compensator are connected to an additional sinusoidal voltage regulator. The input terminals of the AC sinusoidal voltage regulator and the additional AC sinusoidal voltage regulator of the phase are connected to different outputs of the phases of the static power compensator, and the control of the additional AC sinusoidal voltage regulators is carried out by the control system unit. The reactive elements of one or several phases are made controllable with the ability to regulate their reactance and change its nature, the controlled reactive elements are controlled by the control system unit.

EFFECT: technical result of the claimed invention is to expand the functionality of the static power compensator, which allows you to adjust both the reactive and active power of the static compensator and, accordingly, compensate for the reactive and active power of the power transmission line.
