The invention relates to the technical field of energy mutual assistance between a solar thermal power station and a power grid, in particular to a method for fast output adjustment of a steam turbine generator under a dual-carbon target. Under normal conditions, the power plant boiler controls the output of the steam turbine generator through the steam regulating valve; when the load is low and the output of the generator set needs to be reduced, the surplus of the power grid and the low-valley electric energy are used to mix the binary mixed molten salt in the normal temperature molten salt storage tank. Heating, the heated binary mixed molten salt is transported to the high-temperature molten salt storage tank for storage and backup, which can absorb excess power grid and low-trough electricity; when the system load peaks and the system power fails, the high-temperature binary mixed molten salt releases heat and heat The water in the molten salt steam generator forms a preset steam output, and then drives the steam turbine generator through the parallel bypass to complete the energy storage and power generation process of electric energy-thermal energy-electrical energy, and realize the purpose of rapidly increasing the output of the steam turbine generator set. , and the function of heating up to adjust the operating state of the boiler. |
