  • Publication number: 20170306800
    Abstract: A method for coupling a gas turbine connected to a generator and a steam turbine, wherein the generator has an excitation winding, the excitation of which can be changed by changing an excitation current flowing through the excitation winding, the method having the following steps: a) accelerating and/or decelerating the steam turbine in such a way that the coupling takes place with a target coupling angle; b) if necessary, changing the excitation current such that the excitation of the excitation winding changed in this way leads to a changed polar wheel angle, wherein the polar wheel angle is changed in such a way that the achieving of the target coupling angle is supported. In an analogous method, the polar wheel angle is changed for the purposes of improved decoupling. A corresponding control device is for coupling a gas turbine connected to a generator.

  • Publication number: 20170306805
    Abstract: A combined cycle power unit (10) including a gas turbine (16), a heat recovery steam generator (HRSG) (34) to generate steam from an exhaust flow (24) of the gas turbine (16), and a steam turbine (64) driven by the steam generated from the HRSG (34). Steam generated in an evaporator (50) in the HRSG (34) is conveyed through an upstream superheater stage (46a) and a downstream superheater stage (46b) in the HRSG (34). The steam is then conveyed from the downstream superheater stage (46b) to the steam turbine (64). Between the upstream and downstream superheater stages (46a, 46b), the steam flow from the upstream superheater stage (46a) is throttled to a lower pressure to form a reduced pressure steam flow prior to entering the downstream superheater stage (46b) where the steam is reheated to an elevated temperature at the reduced pressure.
