Process analysis for helium cryogenic system of high magnetic field HTS conductor test facility
In order to improve the stability and comprehensiveness of the performance test of HTS conductor,the working condition of the components in the cryogenic system was analyzed,gradient descent method was used to implement the running process of the cryogenic system by MATLAB programming,the optimal operating mode and the control scheme of key parameters such as flow rate at different test temperature were determined in view of the complexity of parameters of the high magnetic field HTS conductor test platform.The results show that at the same test temperature,the system requires the minimum flow when the initial helium pressure is 5 bar,and the helium flow increases and then decreases with the increase of test temperature.The anal-ysis of each parameter in the optimal operation mode of the cryogenic system can provide a reference for the control of cryogenic system in the test experiment of superconducting performance.
