压缩空气储能电站盐穴选址关键流程及控制因素

Critical Process and Controlling Factor of Salt Cavern Site Selection in Compressed Air Energy Storage Power Station

压缩空气储能是一种具有广阔前景的储能技术,盐穴型压缩空气储能电站选址的重要因素是盐穴的相关参数。文章依据中国能建湖北应城300 MW级压缩空气储能电站的建设经验,总结了盐穴选址的关键流程及控制因素。盐穴的选址流程分为资料收集、盐穴勘测及盐穴评估3大阶段共计13个环节。选址阶段的控制指标为盐穴运行压力、容积和密闭性,相关的物探、钻探工作应围绕这三个控制指标开展。盐穴选址流程需要按顺序逐步推进,并做好工作之间的衔接。

Compressed air energy storage(CAES)is a promising energy storage technology,the key parameter of salt cavern is the most decisive factor in salt-cavity type compressed air energy storage(CAES)power station construction,this paper bases on the experiment in CHINA ENERGY DIGITAL Yingcheng 300 MW CAES power station construction,concludes critical process and controlling factor of salt cavern site selection.The main process of site selection includes data acquisition,salt cavern survey,salt cavern assessment three phases thirteen steps.The controlling indices of salt cavern site selection includes the operating pressure,capacity and impermeability of salt cavern,the relative geophysical prospecting and boring work should be carried out based on these controlling factors.The process of salt cave site selection needs to be progressed step by step in order,and the connection between the work should be done.
