The article presents the results of numerical studies and analysis of the feedwater regenerative heating operating modes depending on power unit capacity. The main parameters of this system are the enthalpy of the turbine steam extraction for heaters, as well as the steam consumption in these extractions. The dependences of the turbine unit steam flow rate and the change in expansion process of the steam turbine during the load regulation were investigated. The mathematical model of calculation the thermal power plant for a 300 MW power unit capacity was developed. Following on the results of the calculation conclusions of feed water regenerative heating operating modes at reduced loads of a turbine-generator for a 300 MW unit.
