Self-excitation thyristor static system of STS-2P-420-2500-2,5 UHL4 type for turbogenerator TVV-160-2EU3 of Novo-Salavatskaya ty

Excitation system (ES) is a complex of electrical equipment for controlling excitation of turbine generator (TG) in normal and emergency modes. CB provides PG of PTU with automatically regulated constant excitation current. Excitation of TG is carried out by static thyristor system made with 2 autonomous and equivalent converter-regulating channels, containing thyristor converter (TC), digital automatic excitation regulator with pulse-phase control system, capable of independently providing all modes of TG operation, including excitation boosting mode. TP is powered through a transformer connected to the stator bus bars with voltage of 18 kV. Climatic execution and placement category according to GOST 15150-69.
