Abstract (en)
The method involves operating a power plant in a partial load operation, where a steam turbine of the power plant is divided into a high pressure partial turbine, a medium pressure partial turbine and a low pressure partial turbine. Temperature at an inlet to a reheater unit is increased through a throttling valve that is positioned before the medium pressure partial turbine such that expansion is reduced in the high pressure partial turbine, where the reheater unit is arranged between the high- and medium pressure partial turbines. An independent claim is also included for a power plant.
