Have the function of to reduction greenhouse effects and depletion of the ozone layer positive.
Wind energy, solar energy have the characteristics that discontinuous as a kind of new energy.There are serious in general wind power generation
Wind-abandoning phenomenon, when wind-force is more than the cut-out wind speed of 24m/s, wind energy conversion system decoupling is no longer generated electricity by way of merging two or more grid systems, this makes valuable wind-force
Resource, which does not reach, to be efficiently used, and unavailable phenomenon instead is caused when the energy density of wind energy is larger.
Drive the technology of dynamic power machine very ripe using wind energy conversion system as prime mover.Wind energy conversion system is combined with compressor
It may be implemented not consume electric energy while the compression to air.Application is realized already by the photothermal technique of heat source of solar energy, profit
Can meet the needs of heating air with existing solar thermal collector.
Invention content
The purpose of the present invention is to provide a kind of wind energies and solar combined power generating system.The system mainly for having simultaneously
The area for having abundant wind energy and solar energy, using wind energy as prime mover, driving compressor utilizes later in the sun air pressurized
The hot water that can be generated in heater heats air, last air in turbine expansion work to drive electrical power generators.
Problem of the present invention is that following technical scheme is realized：
A kind of wind energy and solar combined power generating system, it by wind energy conversion system, compressor, valve A, air accumulator, valve B, change
Hot device, turbine, generator, solar heater, heat storage can, pump A, pump B compositions.
Valve A is opened, valve B is closed, and air enters the compressor of wind energy conversion system drive, is flowed after compressor compresses are boosted
It crosses the valve A opened and enters air accumulator.Compressed air is stored in air accumulator.
Valve A is closed, and valve B is opened, and the air in air accumulator flows through valve B and enters heat exchanger, the air in heat exchanger
It is heated by water, the expansion work in turbine of the air after heating drives electrical power generators, completes the air after acting and is discharged into greatly
Gas.
Water in heat storage can becomes hot water by pump A in solar heater heating, and then hot water returns in heat storage can.
Hot water in heat storage can returns after heat release heating air in heat storage can by pump B in heat exchanger.
Air accumulator is embedded in underground and maintains air themperature in a certain range.
