[Objectives]Compressed air energy storage(CAES)is a new type of energy storage system that utilizes the mutual conversion of electrical energy and compressed air potential energy to balance the fluctuation of power grid.The accumulation of relevant experience in the construction and operation of CAES power station is of great significance to the development of CAES technology.In view of the low efficiency of information transfer between the designer and the site,the difficulty of construction control,and the difficulty of overall project process supervision,a wholeprocess intelligent system suitable for CAES power station was proposed.[Methods]Firstly,the construction process of CAES power station was analyzed and its engineering characteristics were found out.Secondly,based on the whole process from design to operation and maintenance of CAES power station,the whole process intelligent construction system of CAES power station was constructed in space and time dimensions.Finally,in the design stage,the key techniques such as forward design drawing were proposed.In the stage of equipment manufacturing,the key technologies such as virtual pre-assembly of equipment were proposed.In the construction stage,the key technologies such as 5D construction management were proposed.In the operation and maintenance stage,the key technologies such as data delivery oriented to operation and maintenance were proposed.[Results]The verification results of a 300 MW CAES demonstration project show that the construction of the whole process intelligent system of CAES power station is reasonable,and the application of key equipment and software provides technical support for the project.[Conclusions]Through the intelligent system of the whole process of CAES power station and its key technologies,the interworking chain of each stage of power station construction is opened,and the information management of the whole life cycle of CAES power station is realized.
