Visualization System Development For Plasma Control Simulation On EAST

One of the basic issues in EAST tokamak plasma discharge is how to achieve stable and reliable plasma control.Based on in-depth understanding of the tokamak device and the plasma behaviors,the plasma control simulation,rooted in the EAST device model,plasma physics model and control model,is very important for accelerating the research and development of the plasma control system and its control algorithms.SPACE(Simulation suites for PlAsma Control on EAST)is a collection applied in EAST plasma control simulation with Python and an open-source implementation for TokSys toolbox.The main function of SPACE is to perform the analysis,design,prediction,and simulation experiments for tokamak plasma control with computer numerical simulation technology based on the models of EAST device model,plasma model and control model.SPACE function library mainly uses the command-line interface to call the functions,which is not intuitive and has a high learning curve and is not conducive to the development of complex simulation research.Therefore,developing a system that meets the visualization requirements of the SPACE function library is of great significance.In this thesis,a visualization system for SPACE has been established using the Python programming language and PySide2 graphical framework.This system is based on the visualization requirements of the SPACE function library and integrates various functional modules of the SPACE function library,including an integrated framework with the unified management and scheduling of each module,Devices module,Controller module,Equilibrium module,Startup module,Waves module.In addition,a customized module function is designed to meet the visualization operation requirements of new function module under the framework of the visualization system in SPACE when some function modules are incomplete,allowing researchers to design and customize their own modules.In order to establish the correctness and effectiveness of the visualization system,functional testing,interface testing,memory performance testing,response speed testing,and reliability testing were performed.The layout of graphical user interface is reasonable and highly operable,and the system works well and gets consistent results with these modules running independently,meeting the functional requirements.Additionally,the system has reasonable memory occupation and fast response to user operation,with stable performance during long-term and high-load operation,meeting the non-functional requirements.The test results indicate that the visualization system can serve as a graphical operation platform for EAST Tokamak plasma control simulation and it is expected to play a significant role in this field.
