    摘要: A steam cooling system ( 30 ) and associated methods are provided which have a first high pressure (HP) steam turbine ( 12 ) having a straight through configuration, a second intermediate pressure (IP) steam turbine ( 16 ) having a straight through configuration positioned adjacent the first HP steam turbine ( 12 ), and a balance piston ( 40 ) positioned adjacent the inlet ( 17 ) of the second IP steam turbine ( 16 ) and between the second IP steam turbine ( 16 ) and the first HP steam turbine ( 12 ). A steam cooling conduit ( 32 ) is preferably positioned to have an inlet adjacent the first HP steam turbine ( 12 ) and an outlet adjacent the balance piston ( 40 ) for providing a steam cooling path therebetween. The system ( 10 ) also has a controller ( 31 ) positioned to control cooling steam pressure, a cooling steam control valve ( 35 ) connected to the conduit ( 32 ) and the controller ( 31 ), a first pressure sensor ( 33 ) in communication with the controller ( 31 ) and positioned adjacent the inlet ( 17 ) of the IP turbine ( 16 ) and downstream from the balance piston ( 40 ) for sensing inlet pressure to the second IP steam turbine ( 16 ), and a second pressure sensor ( 34 ) positioned in communication with the controller ( 31 ) in the conduit ( 32 ) upstream from the first pressure sensor ( 33 ) and the balance piston ( 40 ) and downstream from the cooling steam control valve ( 35 ) for sensing conduit cooling steam pressure so that the cooling steam control valve ( 35 ) operationally opens and closes to maintain the cooling steam conduit pressure at a predetermined level greater than the inlet pressure of the second IP turbine ( 16 ).
