【摘要】：將擴容蒸發(fā)式槽式太陽能蒸汽發(fā)生系統(tǒng)與600 MW燃煤機組聯(lián)合,構(gòu)建了光-煤互補復(fù)合發(fā)電系統(tǒng),建立了其變工況計算模型及技術(shù)經(jīng)濟評價模型,從太陽能側(cè)、汽輪機側(cè)及復(fù)合發(fā)電系統(tǒng)3方面進行了熱力性能分析及技術(shù)經(jīng)濟性評估。結(jié)果表明,光-煤互補復(fù)合發(fā)電系統(tǒng)具有顯著的節(jié)能減排效果,系統(tǒng)產(chǎn)生的太陽能蒸汽取代汽輪機第1段抽汽時效果最為明顯,太陽能側(cè)各指標(biāo)隨取代抽汽段數(shù)增大呈階段性下降趨勢,太陽能到電能的轉(zhuǎn)換效率最高為23.5%;各集成模式下的單值發(fā)電成本相差不大,平均為0.19元/(kW·h);從凈現(xiàn)值判斷取代第1段抽汽是較好的選擇,從凈現(xiàn)值率、盈利能力判斷取代第2段抽汽是較好的選擇。
[Abstract]:By combining the expanded evaporative trough solar steam generating system with 600 MW coal-fired unit, the optical-coal complementary power generation system is constructed, and its off-condition calculation model and techno-economic evaluation model are established. Thermal performance analysis and technical and economic evaluation of steam turbine side and composite power generation system are carried out. The results show that the photo-coal complementary power generation system has remarkable energy saving and emission reduction effect, and the solar steam produced by the system is the most effective when it replaces the steam extraction of the first stage of steam turbine. The indexes of solar side decreased gradually with the increase of the number of alternative extraction stages, and the conversion efficiency from solar energy to electric energy was the highest of 23.5kyr; The cost of single value generation in each integrated mode is not different, with an average of 0.19 yuan / (kW h);. It is a better choice to substitute the first stage extraction from the net present value (NPV), and from the NPV rate and the profit ability to replace the 2nd stage extraction.
