Abstract:

The super-synchronization speed control assemblies for the two 2500kW induction motors have been developed successfully in order to meet the need for toroidal field increasing in HL-2A tokamak. Based on the a.c./a.c. cycloconverter, the speed of each 2500kW motor has been regulated by means of vector control technology for double-fed motor. The highest rotate speed of the two 80MVA generator sets have been increased from 1488rpm rated speed to 1650rpm and the released energy of each generator set in one pulse discharge can reach 500MJ. Therefore the toroidal field system is able to reach 2.8T for experiment.

Key words: Double-fed motor, a.c./a.c. cycloconverter, Vector control, Super-synchronization speed control assembly

摘要：

为了满足HL-2A环向磁场的要求，成功研制了两套2500kW感应拖动电机的超同步调速装置。基于交-交变频器，通过对每套2500kW拖动电机采用双馈电机矢量控制技术进行调速后，将两台80MVA机组的最高转速由以前的额定转速1488rpm提高到了1650rpm，每台机组的一次脉冲释能达到500MJ，使HL-2A装置具备了环向磁场达2.8T的能力。
