| 摘 要： | 现有的HL-2A实时平衡重建系统采用的是网格尺寸为33×33,将无法满足HL-2M装置对控制精度和速度要求.为此开发了网格尺寸为129×129的重建系统,并通过GPU并行、算法重构等优化方法,使得新的重建系统在保证计算精度的情况下能够使得每一次平均重建计算维持在600μs内,可满足HL-2A和HL-2M中周期为1ms等离子体控制系统对重建系统精度和速度要求.

| Abstract: | The HL-2A equilibrium reconstruction subsystem with grid dimension 33×33 didn't meet the control accuracy and speed for the HL-2M tokamak, so a new equilibrium reconstruction subsystem with grid dimension 129×129 was developed. This subsystem can run a time slice in 600μs by solving the G-S function and reconstructing some algorithm of calculating some parameters and meet the requirements of the control system about real-time and accuracy on HL-2A and HL-2M tokamak. |
