[摘要]隨著風(fēng)能、潮汐能和太陽能等可再生能源的大量推廣普及,壓氣儲(chǔ)能(CAES)作為一種有效可行的將不穩(wěn)定電流并入電力系統(tǒng)的方法正在受到各國研究學(xué)者的重視,德國、美國甚至都已經(jīng)建成了商業(yè)運(yùn)營的設(shè)備。我國目前雖然沒有此類工程,但我國巨大的清潔能源市場給這一技術(shù)帶來了巨大的應(yīng)用前景,目前已有越來越多的學(xué)者對這一技術(shù)進(jìn)行研究。構(gòu)建了溫度-氣液兩相滲流-力學(xué)多場耦合模型,并對其作出細(xì)致的描述;推導(dǎo)了儲(chǔ)氣洞室在多物理場耦合下的微分方程;利用數(shù)值計(jì)算,分析了不同物理場耦合作用下儲(chǔ)氣洞室的溫度擴(kuò)散、巖石應(yīng)力變化及流體壓力變化特點(diǎn)。最后,根據(jù)分析結(jié)果對實(shí)際問題提出了自己的建議。

Abstract: With the popularization of renewable such as energy wind energy and solar energy, compressed air energy storage (CAES), a practical and efficient way to solve connect power into electricity system, become more and more popular around researchers all over the world. The German and America have even make this technique into business. Although China has not this kind of project, its huge market for clear energy will give this technique a large stage and this makes some Chinese researchers start to study this technique. According to energy balance, mass balance and static equilibrium, a multi-field coupled model for CAES was built and multi-field couplings′ governing equations were deduced. The temperature diffusivity, rock stress and fluids pressure were also analyzed. In the end, some suggestions to practical problem based on the analysis were proposed.
Keywords: compressed air energy storage; two-phase flow; multi-field coupling; numerical analysis
