摘要

The technical possibility of transferring the T-125/150 steam turbine of 450 CCGT unit into motoring drive mode is considered as an alternative to stopping the steam turbine when transferring the CCGT unit to the GTU based CHP mode. To simulate the temperature state of the flow part of a steam turbine in steam-free and motoring drive modes, it is suggested to take into account the design features of a steam turbine. To illustrate the possibility of controlling the temperature of steam turbine stages, the results of model calculations show the temperature distribution graphs after their stabilization along the flow-through part of T-125 turbine for two modes of turbine operation - nominal and motoring drive modes. The possibility of adjusting the steam temperature at the inlet to the steam turbine and at the outlet from the LP cylinder is shown, whereby the duration of the starting operations of the steam turbine and the loading of the CCGT unit 450 to the nominal mode in this case is reduced by 20 min in comparison with the steam turbine shutdown mode.
