METHOD AND STEAM POWER PLANT COMPRISING AN AUXILIARY STEAM GENERATOR USED AS AN ADDITIONAL FREQUENCY REGULATION MEASURE AND A PRIMARY AND/OR SECONDARY REGULATION MEASURE

摘要

The invention relates to a method for the immediate rapid and/or temporary increase in output of a steam power plant (1) in particular a coal fired power plant and to a steam power plant (1) having a water steam circuit. The steam power plant (1) comprises a water steam circuit a turbine (10) arranged in the water steam circuit and an auxiliary steam generator (80) by which auxiliary steam consumers (83) are supplied with auxiliary steam (81) when the steam power plant (1) is started and/or shut down. According to the invention and upon a power demand to the steam power plant (1) outside the period of starting or shutting down the auxiliary steam (81) is fed from the auxiliary steam generator (80) into the water steam circuit of the steam power plant (1) the turbine (10) of the steam power plant (1) is thus supplied with additional steam and the output of the steam power plant (1) is immediately rapidly and/or temporarily increased.
