Abstract: A combine cycle power plant is presented. The combine cycle power plant includes a gas turbine, a heat recovery steam generator, a main steam turbine and a supercritical steam turbine. The supercritical steam turbine may be operated as a separate steam turbine that may be not a single steam turboset with the main steam turbine. The supercritical steam turbine receives supercritical steam generated in the heat recovery steam generator to produce power output. Exiting steam from the supercritical steam turbine may be routed to the main steam turbine. The supercritical steam turbine may be operated at a rotational speed that is higher than a grid frequency. The rotational speed of the supercritical steam turbine may be reduced to the grid frequency via a gearbox.

Abstract: A power generation system includes a power generation module coupled to a thermal storage system via a heat transfer connection. The thermal storage system includes a heat storage medium contained in a storage tank. The thermal storage system is operable for receiving an energy input in the form of electrical energy or mechanical energy at a first point in time, converting the input energy into thermal energy, transferring the thermal energy to the heat storage medium to thereby cause an increase in enthalpy of the heat storage medium, and storing the thermal energy in the heat storage medium. The power generation module converts the stored thermal energy, which is recovered from the thermal storage system via the heat transfer connection, into an electrical power output. The stored thermal energy is recovered from the thermal storage system at a second point in time temporally shifted from the first point in time.

Abstract: It is proposed that, during the operation of a steam turbine of a steam power plant, the internal pressure and also the internal temperature and, in the region outside it, the external temperature be determined in at least one steam-carrying component. As a result of a change in the operating state, in particular in the event of a load change, then, the abovementioned values vary, so that, under some circumstances, the mechanical stresses which in this case act on the steam-carrying component become unacceptably high. Consequently, a spatial temperature distribution and a reference stress of the steam-carrying component are determined from the abovementioned values and compared with a material limit stress. If the reference stress is greater than the material limit stress, a limit steam pressure desired value is determined, and at least one steam valve is set in such a way that the steam pressure on the steam-carrying component corresponds approximately to this limit steam pressure desired value.
