FIELD: internal combustion engines.
SUBSTANCE: invention relates to surface gas turbine power plants with two-stage gas turbine device for generation of electric energy. Invention comprises two cascades. First cascade comprises the first shaft, the first compressor and the first turbine. Second cascade comprises at least second shaft and second turbine. Shafts of the first and second cascades are made with possibility of rotation independently from each other. Present invention additionally comprises a first generator and a second generator, having substantially equal rated power, and rotating parts of the first generator and the second generator have substantially equal values of rated speeds of rotation, and at least 60 % of total output energy supplied to said load in the form of electric and rotary energy are generated by two electric generators.
EFFECT: higher efficiency of power generation.
