description: This work is devoted to determination of optimum parameters and structure of CCPP utilization circuit on the basis of GTE-65 unit, developed by Power Machines, JSC. Tasks solved in the course of research: 1. Recalculation of GTU nominal parameters taking into account input and output tract resistances. 2. A choice of parameters of the combined unit with a single-pressure steam circuit, determination of its efficiency and a choice of the main equipment of the utilization circuit. 3. Selection of parameters for a combined unit with a two-pressure steam circuit, determination of its efficiency and selection of the main equipment of the utilization circuit. 4. Determination of methods to achieve the highest efficiency of CCGT based on GTE-65 unit. As a result of the work it was concluded that the choice of optimum parameters insignificantly affects the CCU efficiency. In order to noticeably increase the CCGT efficiency, it is necessary to complicate the utilization circuit scheme. For the CCGT based on the upgraded GTE-65 unit, the optimal utilization circuit scheme is the two-pressure steam circuit without intermediate steam superheating due to insufficiently high gas temperature at the turbine outlet.
