CAES (Compressed Air Energy Storage) system is mainly applied to large-scale power storage, 1.5MW advanced CAES comprehensive experimental platform mainly consists of compression, expansion, thermal storage subsystem, the platform can release the power of 1.5MW, the maximum pressure 32MPa, the heat storage temperature of 150 Deg., cold storage temperature as low as -196 Deg., it is a comprehensive experimental platform for advanced systems and key components of the CAES research and development.

The comprehensive experimental platform mainly consists of self-designed 1.5MW release subsystem, 250kW compression subsystem, 5GJ compression heat storage subsystem, 10GJ cold storage heat exchanger and 32MPa gas storage room. On this basis, laboratory Technicians have also developed some independent function on the platform, including high frequency signal acquisition and online analysis of three dimensional complex flow field which appears in compression and expansion system, real-time acquisition and display of wide range temperature field which appears in thermal storage system, automatic control system of platform integration and joint operation and so on. Relying on the experimental platform, the researchers can also conduct research on CAES basic scientific issues in addition to carry compressed air energy storage system and key components experiment, such as process coupling and energy transfer mechanism of CAES, heat transfer and thermal storage characteristics and mechanism of gas liquid solid multiphase flow and supercritical fluid in the restrictions of spatial scales, the mechanism of flow and energy loss in the high load compressors and turbines.
