Based PLC and Configuration Software for Supervisory System of Screw Compressor Station
Jin Yibin Zhuang Ming Institute of Plasma Physics Chinese Academy of Science,Hefei ,Anhui province 230031,China Abstract: The HT-7U fully superconducting tokamak is an advanced steady-state plasma physics experimental device. The cryogenic system for HT-7U tokamak supplies the forced flow supercritical helium to cool down the 16 TF coils and 14 PF coils which are made of NbTi/Cu CICC and operate at 3.8K. Screw compressor station is a subsystem of HT-7U cryogenic system. The paper discusses the survey system of screw compressor station based on PLC and configuration software in detail. The hardware and software structure, control philosophy and functions of the survey system are presented.
