Abstract
A method for starting a combined cycle power plant () includes loading the gas turbine unit (), providing a starting temperature (T) for the steam supplied to the steam turbine (), while the control valve () is regulated controlling the temperature of the steam at a temperature substantially equal to the starting temperature (T) at a position (P) downstream of the control valve () and upstream of the rotor (), when the control valve () is substantially fully open, supplying steam to the steam turbine () at the starting temperature (T). The steam temperature is controlled by controlling the steam temperature upstream of the control valve () in accordance with the temperature drop caused by the control valve () when the steam passes through it.
