Description

A kind of multi-level solar and the power generation of other energy complementary thermals and polygenerations systeme
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.
Solar power generation mainly has two kinds of photovoltaic and photo-thermal, photovoltaic generation that silicon or other special materials is needed to generate electricity, Photo-thermal power generation has slot type, tower and butterfly.The mainly large-scale power generation of thermoelectricity, and mainly single-stage power generation system, in this way Electricity generation system, main or according to the power generation that traditional coal power generation principle is realized, shortage fits dynamic solar source It answers, in addition to this, since the collecting temperature of main solar power generation is single, because without also without multilevel power generation system, China leading low-temperature water heating technology and industry cannot be thus applied to this field, while existing solar energy thermal-power-generating lacks On a small scale, family oriented, cost effective heat generating system, while existing solar vacuum heat-collecting pipe is mainly used in solar energy Water heater, since collecting temperature is low, direct generation of electricity efficiency is low, thus limits its application.Distributed energy resource system refers to will Source system by small-scale, low capacity, modularization, it is distributed in a manner of be arranged in user terminal, come that transmitted in both directions is hot and cold, electric energy.By In energy utilization rate and Supply Security can be improved, realizes energy-on-demand and provide more more options, distributed energy to the user Source system becomes the important development direction of global power industry and energy industry.The energy utilization rate of distributed energy resource system is much Rely on large-scale main power station by electric power from power plant to the central power supply system of terminal user's one-way transmission higher than majority state.Hair Power plant's finally fuel energy can only burn 1/3 thermal energy generated be converted to electric energy, and nearly 50% heat energy loss, transmission link 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.
