【摘要】 随着风能、潮汐能和太阳能等可再生能源的大量推广普及,压气储能(CAES)作为一种有效可行的将不稳定电流并入电力系统的方法正在受到各国研究学者的重视,德国、美国甚至都已经建成了商业运营的设备。我国目前虽然没有此类工程,但我国巨大的清洁能源市场给这一技术带来了巨大的应用前景,目前已有越来越多的学者对这一技术进行研究。构建了温度-气液两相渗流-力学多场耦合模型,并对其作出细致的描述;推导了储气洞室在多物理场耦合下的微分方程;利用数值计算,分析了不同物理场耦合作用下储气洞室的温度扩散、岩石应力变化及流体压力变化特点。最后,根据分析结果对实际问题提出了自己的建议。更多还原

【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.更多还原
