NPO Saturn is an integrator and supplier of PGU-170 - a ready-made “energy island” for the construction of new and modernization of existing energy facilities, including technical re-equipment of existing TPPs and state district power stations (modernization of steam-power units).
Depending on the layout of energy facilities, NPO Saturn offers two schemes of PGU-170:
single-shaft scheme: one 165 MW generator on one shaft with a gas turbine engine and a steam turbine - simple layout, lower cost of ownership;
two-shaft scheme: two generators with a capacity of 110 MW (on a gas turbine engine shaft) and 60 MW (on a steam turbine shaft) - high integration flexibility, high maneuverability.
Application:
modernization of steam power units of existing TPPs and state district power plants - transition to new highly efficient combined-cycle technologies of electric power generation;
generation of electric energy in a combined cycle in basic, semi-peak and peak operating modes.
Advantages:
PGU-170 has high efficiency in the combined cycle (50%) as well as fuel efficiency, good dynamics during transients, flexibility of integration into existing energy facilities, low cost of ownership and quick payback, environmental characteristics that allow locating energy facilities in the city.
