Turbogenerator of TVV-350-2U3 type for CHPP-22, unit No.10 of Mosenergo branch of PJSC Mosenergo.

Turbogenerator (TG) TVV-350-2U3 is designed to generate electricity in continuous rated mode of operation in accordance with GOST IEC 60034-1-2014 when directly connected to a steam turbine (PT) and installed indoors. The TG is a three-phase synchronous electric machine with implicit pole rotor and hydrogen-water cooling. TG consists of a stationary part - stator, which includes a core and winding, and a rotating part - rotor, on which is placed the excitation winding, powered by direct current. Advantages of TG TVV-350-2U3: high efficiency, reliability, increased heat resistance, ease of repair and operation in various climatic conditions, including modes with reactive power consumption. Oil supply of bearings and shaft seals of TG is performed from the oil system of TP. The TG rotation direction is in accordance with the turbine rotation direction.
