The results of the research presented in this paper refer to an upgrade of a power generating unit with a supercritical steam turbine of a moderate live steam temperature. The upgrade project involves replacing the high pressure part with a turbine driven by a high live steam temperature and adding a gas turbine. The aim of the upgrade is to increase power generation efficiency. The specific problem analyzed in the paper corresponds to the matching between the gas and steam turbine especially in off-design conditions. The analysis is based on the numerical modeling of the thermodynamic cycles. Various conditions of the operation were simulated. The results obtained enable efficiency to be assessed in the analyzed variants.
