New energy hybrid power station with cascaded steam turbine

Abstract

The invention relates to a power station, in particular to a new energy hybrid power station with a cascaded steam turbine, which comprises a steam generator and a main steam turbogenerator. The main steam turbogenerator is connected to a steam output end of the steam generator, a main steam pressure stabilizer is disposed between the steam generator and the main steam turbogenerator, a medium input end of the steam generator is connected to a high-boiling-point medium tank via a pipe and a liquid pump, a tail gas heater is mounted on a flue, a medium input end of the tail gas heater is connected to a low-boiling-point medium tank via a pipe and a liquid pump, and a medium output end of the tail gas heater is connected to an auxiliary steam turbogenerator via a pipe and an auxiliary steam pressure stabilizer; and the auxiliary steam turbogenerator is provided with an auxiliary steam recovery pipe, the auxiliary steam recovery pipe is connected to the low-boiling-point medium tank via an auxiliary condenser and a ground source condenser, the auxiliary condenser is mounted at the bottom end of a hurricane barrel, and a wind driven generator is mounted at the top end of the hurricane barrel. The new energy hybrid power station with the cascaded steam turbine comprehensively utilizes heat energy, reduces environmental pollution, can greatly increase efficiency of nuclear power plants and coal-fired power plants, is fine in electric energy quality, low in investment and stable in operation, and has high social benefit and economic benefit.

Description

technical field [0001] The invention relates to a power station, in particular to a cascade steam turbine mixed new energy power station. Background technique [0002] Coal-fired power plants, nuclear power plants and other power plants that use steam turbines to generate electricity are currently the main power plants in the world, accounting for about 80% of the share. The thermal efficiency of these power plants is generally less than 50%, and other energy such as steam waste heat is discharged to the atmosphere. Serious waste of resources and pollution of the environment. Due to the large investment and poor power quality of new energy power plants, its application scale is limited. In particular, the key technologies for grid-connected new energy power plants have not been fully overcome, so new energy power plants cannot be used as main power plants at present. Combining new energy technologies with traditional coal-fired power plants and nuclear power plants can perf...
