Creation of a methodology for calculating the gas circuit of a combined utilization turbine plant

This article discusses the gas turbine engine of the GTE 160 brand of the Power Machines concern. This gas turbine engine is part of a two-circuit Combined Cycle gas plant (CCGT 450) and is located at the Southern CHP plant in St. Petersburg. The article developed a method for calculating the gas circuit of this CCGT, a software implementation of the technique, and verification of the data obtained. During the calculation, the following were determined and calculated: compressor, combustion chamber, gas turbine parameters when operating as part of a CCGT. The main parameters of the GTU, their dimensions and weight are obtained.
