Method for adapting the output of a steam-turbine power station, and steam-turbine power station

Abstract

Disclosed is a method for rapidly and flexibly adapting the output of a steam-turbine power station (1), preferably for adapting the output to altered network loads, more preferably for providing a positive and / or negative network operating reserve as required, and especially preferably for providing a primary operating reserve and / or a secondary operating reserve. According to the invention, heatreleased during the discharge of at least one electrically chargeable thermal store (6) is coupled into a feedwater heater section (3) of the power station (1).

Description

technical field

[0001] The invention relates to a system for quickly and flexibly adapting the power of a steam turbine power plant, preferably for adapting the power to changed grid loads, more preferably for supplying grid-regulated power according to demand, particularly preferably for supplying primary Method of regulating power and / or sub-regulating power. Furthermore, the invention relates to a steam turbine power plant with at least one steam turbine and further plant components required for the power generation process, such as feedwater preheaters, evaporators, steam superheaters, pumps and condensers as well as feedwater container. Particularly preferably, the present invention relates to a power class greater than 50 MW by means of pulverized coal combustion el. , especially preferably greater than 100MW el. , such as greater than 400MW el. power station. Background technique

[0002] Due to the deregulation of the energy market, flexible load operation of po...
