Abstract: The disclosure refers to a method for providing a frequency response for a combined cycle power plant connected to an electric grid. The combined cycle power plant includes a gas turbine engine and a steam turbine engine. The steam turbine engine includes a boiler, a steam turbine, a pump, a condenser, a bypass for the steam turbine, a steam admission control valve. The steam turbine engine operates with the bypass closed or at least partly open to supply steam from the boiler to the condenser bypassing the steam turbine, and/or with the steam admission control valve at least partly open. The method comprises regulating the output load of the combined cycle power plant by regulating the steam admission control valve and/or by regulating the steam flow through the bypass in response to a frequency change of the electric grid. The output of the gas turbine can also be adjusted, such that steam generated by the boiler is sufficient to achieve the target load for the steam turbine.

Abstract: The invention relates to a method for starting a steam turbine. The method involves pre-warming the steam turbine with a steam in which 65% of an energy used to pre-warming the steam turbine is derived from a latent heat energy of the steam.
