The measurement and control system design of constant pressure and zero volatile low-temperature dewar for superconducting magnetic energy storage system

Low-temperature dewar for 1MJ superconducting energy storage system is designed into constant pressure and zero volatile control system. We completed design principles, organizational structure and measurement functions of measurement and control system of 1MJ SMES system´s low-temperature dewar. We also achieved the integration of hardware and development of software. The software development using NI LabVIEW to achieve. According to the measured data, we can concluded that the designed low-temperature dewar is the constant pressure and zero volatile control system.
