Abstract: A method for starting-up a steam turbine of a combined-cycle power plant is provided. The combined-cycle power plant includes a gas turbine and a steam power generation system having a steam turbine. The combined-cycle power plant activates at least one electric generator connectable to an electric grid. The gas turbine includes a compressor, such that, during starting-up of the steam turbine, both the gas turbine and the steam turbine are in operation. The steam turbine adjusts its load as a function of the load of the gas turbine in such a way that the sum of the load provided by the gas turbine and of the load provided by the steam turbine is equal to the auxiliary power demand of the plant. The load exported to the grid is equal to zero.

Abstract: Method for operating a combined-cycle power plant is provided. The plant includes at least a gas turbine and at least a steam power generation system. The plant activates at least one electric generator connectable to an electric grid, wherein the gas turbine includes a compressor. The steam power generation system includes a steam turbine, a heat recovery steam generator and a bypass line. The method is such that the gas turbine de-loads to a condition, where the compressor operates at its nominal speed. The method is such that the steam turbine de-loads in coordination with the de-load of the gas turbine, to a condition where the total load exported by the plant to the grid is substantially equal to zero, being both the gas turbine and the steam power generation system connected.
