About company Products Quality Technology Press center Documents Order Contacts Reactor equipment homeProductsReactor equipment Controlled shunt reactors of transformer type (UShRT) A unique technique for modern power engineering is equipment for flexible networks (FACTS), which includes USHRT. The equipment of the future, as power engineers are called, is produced by units of companies in the world, including TT LLC. UShRT combines a step-down transformer and a thyristor-reactor group STK and is a conventional two-winding transformer with a short-circuit voltage of 100%. The regulation of the angles of ignition of thyristor valves connected in parallel with the secondary winding provides a change in the current from zero to the nominal value in the secondary and, accordingly, the primary winding of the CSRT. In this case, the power of the thyristor valves is equal to the rated power of the CShRT. Appointment of USHRT, performance of the following most important functions: • voltage regulation in line, • increased capacity, • limitation of the voltage rise and switching surges, including when the lines of idling, • arc interruption in the pause-phase automatic reclosing (APA) with the function of adaptive management, • an increase of static and dynamic stability, • reduction of the number of switchings of equipment designed to maintain the voltage within acceptable limits when changing the operating mode of the power system (tap changers on transformers and autotransformers) These functions can be performed by CSR only of the transformer type with a high speed of 0.03–0.07 s. The performance indicator is of particular importance for the development of the principle of adaptive control of the modes of electrical networks. The Togliatti Transformer mastered the technologies and production of USHRT 60 MVAr / 500 kV, 50 MVAr / 220 kV, 50 MVAr / 110 kV The equipment is installed in large Russian power centers. Today, projects USHRT 25 MVAr and 100 MVAr for 35 and 110 kV are under development. The scope of supply of USHRT equipment includes: • electromagnetic part; • high voltage thyristor valves; • automatic control and protection system; • software (adapted for a specific object and a specific line), measuring current and voltage transformers; • switches; • disconnectors, etc .; Complete delivery of USHRT, adjustment and commissioning is carried out jointly with JSC "Aydis group", JSC "Nidek ASI VEI", LLC SPC "Enercom-Service".
