Under the project of expansion of condensing power station of Kemerovsky coke-chemical integrated plant new steam turbine power unit rated at 12 MW was commissioned. In result total electric output of the station was increased from 12 to 24 MW and provided all demands of the enterprise in electric power. The power unit was developed on the base of K-12-1.2 steam turbine supplied by Kaluga turbine plant and ТGP-10.5-12000-2UKhL electric generator with brushless excitation system manufactured by ELSIB. ТGP-10.5-12000-2UKhL electric generator has high operational parameters.
