Description
Technical field
The present invention relates to a kind of co-generation unit, specifically a kind of multi-level solar and other energy complementary thermals generate electricity and
Polygenerations systeme.
Background technology
Existing solar energy is a kind of clean regenerative resource, inexhaustible.China is a solar energy
The more rich country of reserves, especially the Northwest have the abundant sun such as Tibet, Xinjiang, Qinghai and Inner Mongolia
Energy resource, along with these ground density of population are relatively low, flat provides advantage to build photo-thermal power station.Sand ground,
Gobi desert, desert etc. build solar thermal power generation power plant, can not only produce clean green energy resource, solar irradiation is not in winter
Can also be that nearby residents heat in the case of foot.Using abundant, comparatively clean natural gas is right as supplementary energy
Environmental hazard is small, if control is proper the use of conduction oil will not pollute the environment.

Nearly 10% thermal energy is lost.Moreover, current 20% capacity of installed generator is served only for meeting the needs of peak times of power consumption.Therefore, this
A little generating set run times only account for the 5% of whole unit operation times, and generated energy only accounts for the 1% of power generation total amount.Due to relying only on
Several main lines transmit electric power, and supply line's congestion problems of central power supply system are increasingly prominent.Supply of electric power surplus forces
Public public institution meets peak times of power consumption demand by pollution higher and the lower energy power generation of efficiency, rather than simple
Dump power is distributed to the high market of demand by ground again from the low market of demand, to cause energy utilization rate more low
Under.However, distributed combined heat and power generation unit is all the cogeneration of heat and power realized using traditional energy, and the not thermoelectricity of heat accumulating type
Coproduction unit, the application of new energy and cogeneration units of such obstacle.Distributed solar heat generating system is for too
Sun can acquire the generation mode of the big use of area, but how multistage distributed solar energy electricity generation system carries out, and needs to carry out
Research.Simultaneously because the fluctuation characteristic of solar energy and uncertain feature, thus the power generation of continuous-stable is can not achieve, still,
Power supply that is grid-connected and needing stabilization, otherwise will threaten to the stability of power grid and reliability after power generation, thus need to stablize
Solar power generation.
