电子回旋共振加热稳态运行控制系统设计

Design of Steady Operation Control System of Electron Cyclotron Resonance Heating

为了实现EAST上电子回旋共振加热(ECRH)系统在长脉冲放电下的稳态运行,设计了一套ECRH稳态运行控制系统。该系统通过多种模式切换,运用重新启动和多组回旋管轮流运行的方案提高ECRH系统在EAST装置的400~1000s长脉冲放电过程中的连续运行能力。本设计采用NI CompactRIO及其组件作为下位机,使用LabVIEW语言编写程序。本系统响应迅速,时序准确,能够实现长脉冲放电下ECRH系统的稳态运行。

In order to realize the steady-state operation of the electron cyclotron resonance heating(ECRH)system on EAST under long pulse discharge,a set of ECRH steady-state operation control system is designed.The system uses multiple modes of switching,restarting and multiple groups of gyrotrons in turn,to improve the continuous operation of the ECRH system during the 400—1000 s long pulse discharge process of the EAST device.This design uses NI CompactRIO and its components as the lower computer,and uses Lab VIEW to write programs.The system responds quickly,with accurate timing,and can achieve steady-state operation of the ECRH system under long pulse discharge.
