An outlet of a water supply system is communicated with an inlet of an evaporator, an outlet of the evaporator is divided into two paths, one path is communicated with an inlet of a superheater, the other path is communicated with an inlet of a steam-water separator, an outlet of the superheater is divided into two paths, and the steam-water separator is communicated with an inlet of the steam-water separator. Wherein one path is communicated with an inlet of the steam turbine, the other path is communicated with an inlet of the condenser, an outlet of the steam turbine is communicated with the inlet of the condenser, the auxiliary steam system is communicated with the steam-water separator, a water outlet of the steam-water separator is communicated with an inlet of the superheater, and an outlet of the superheater is communicated with an inlet of the water supply system. A water outlet of the steam-water separator is communicated with an inlet of the drain flash tank, an outlet of the drain flash tank is di
