Development and Implementation of Automatic Conversion of Steam-Gas Power Unit from Compound Cycle Mode to Steam-Power Mode Without Shutdown of the Unit

详细

Conversion of the power unit of station No. 5 of the Razdan thermoelectric power plant, which is not equipped with a bypass chimney, from a compound (steam-gas) mode to a steam power unit mode in scheduled and emergency shutdown of the gas turbine plant is described. The importance of the present study is due to the need to maintain the power unit in service when the gas turbine is shut down, as a consequence of which the operating reliability of the power unit as a whole is increased and the reliability of the delivery of power to the system and stability of the power system assured, while losses associated with shutdown and subsequent start up of the equipment are reduced.
