    摘要: Various embodiments include a system (2) having: a computing device configured to control a power plant system (4) including a steam turbine (ST (6)), a gas turbine (GT (16)), and a heat recovery steam generator (HRSG (14)) fluidly connected with the ST (6) and the GT (16), by performing actions including: obtaining data representing a target steam specific enthalpy in a bowl section (30) of the ST (6); determining a current steam pressure at an outlet of the HRSG (14) and a current steam temperature at the outlet of the HRSG (14); calculating an actual steam specific enthalpy in the bowl section (30) of the ST (6) based upon the current steam pressure at the outlet of the HRSG (14) and the current steam temperature at the outlet the HRSG (14); and modifying a temperature of steam entering the ST (6) in response to determining that the calculated actual steam specific enthalpy in the bowl section (30) differs from the target steam specific enthalpy in the bowl section (30) by a threshold.
