Beschreibung
Zusammenfassung:	The embodiment of the utility model discloses a combined frequency modulation system for flywheel energy storage coupling steam turbine regenerative system energy storage. The combined frequency modulation system mainly comprises a condenser, a condensate pump, a shaft seal heating device, a low-pressure heating device, a deoxidizing device, a high-pressure heating device, a boiler, a steam turbine set and a power generator which are sequentially connected. The steam turbine set is connected with the high-pressure heating device, the deoxidizing device, the low-pressure heating device and the condenser to form the steam turbine heat regeneration system. The combined frequency modulation system further comprises a rectification transformation device and a flywheel energy storage device, and the flywheel energy storage device is connected with the output of the generator through the rectification transformation device. On one hand, the feed water temperature and the condensed water flow are designed as variable
