REACTOR-THYRISTOR START-CONTROL DEVICE ON HIGH SIDE OF TRANSFORMER SUBSTATION Russian patent published in 2024 - IPC H02M5/25 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to electric power systems, and can be used for switching on, off and continuous voltage control of a transformer substation in all branches of power supply systems. Objective of the invention is to expand the range of voltage regulation and improve the sinusoidal voltage at the input of the power transformer of the substation and at electric power consumers with smooth and discrete regulation of voltage between the nominal and maximum voltage level of the network. Reasonable field of application of the proposed device is transformer substations of all branches of power supply systems with voltages of 35/(10-6) kV and (10-6)/0.4 kV, where positive deviation and fluctuation of voltage is mainly observed in power supply systems. Most expedient field of application of the proposed device is power supply systems, where there is a need to provide multistage narrow-range voltage control with high technical and economic indicators.

EFFECT: as a result of solving the set task, improvement of the quality of electricity and increase in the energy performance of the power transformer and consumers of electricity will be achieved when regulating the voltage between the nominal and maximum voltage level of the network; in addition, as in the prototype, the advantages of the stabilization property of the device are preserved at maximum and nominal voltage level of the network, as well as controlled switching on and off of the transformer substation.
