【摘要】：針對(duì)互聯(lián)運(yùn)行的分布式冷熱電聯(lián)產(chǎn)系統(tǒng)進(jìn)行節(jié)能優(yōu)化研究,在分布式冷熱電聯(lián)產(chǎn)系統(tǒng)網(wǎng)絡(luò)中通過(guò)系統(tǒng)間的電、冷、熱的互相傳輸,提升網(wǎng)絡(luò)的整體節(jié)能性能.建立了兩個(gè)并網(wǎng)運(yùn)行的分布式冷熱電聯(lián)產(chǎn)系統(tǒng)的互聯(lián)運(yùn)行優(yōu)化模型,該模型以總相對(duì)節(jié)能率最大為目標(biāo)對(duì)系統(tǒng)進(jìn)行運(yùn)行優(yōu)化.選擇賓館和寫(xiě)字樓的兩個(gè)分布式冷熱電聯(lián)產(chǎn)系統(tǒng)進(jìn)行案例分析,系統(tǒng)分別根據(jù)賓館和寫(xiě)字樓的冷熱電負(fù)荷進(jìn)行優(yōu)化設(shè)計(jì),然后利用互聯(lián)運(yùn)行優(yōu)化模型對(duì)其運(yùn)行狀態(tài)進(jìn)行優(yōu)化,使總相對(duì)節(jié)能率進(jìn)一步提升.通過(guò)優(yōu)化,該案例的總相對(duì)節(jié)能率由互聯(lián)前的23.9%提升到28.5%.
[Abstract]:The energy saving optimization of distributed cogeneration system is studied, and the transmission of electricity, cooling and heat between the systems is carried out in the distributed cogeneration system network of cold, heat and electricity. To improve the overall energy-saving performance of the network. Two grid-connected distributed cogeneration system operation optimization model is established. The model takes the total relative energy saving rate as the goal to optimize the operation of the system. Two distributed co-generation systems of cold, heat and power in hotel and office building are selected for case study. According to the cooling and thermal power load of the hotel and office building, the system is designed optimally, and then the operation state of the system is optimized by using the interconnected operation optimization model, so that the total relative energy saving rate can be further improved. The total relative energy saving rate in this case increased from 23.9% before interconnection to 28.5b.
