Description
Tokamak as the most promising way to achieve fusion energy, the reliability of its plasma control system (PCS) is of great importance. J-TEXT Real-Time Framework (JRTF) is the next generation real-time framework for tokamak plasma control of J-TEXT. Introducing object-oriented programming (OOP) technology, JRTF is an advanced framework and can be a future candidate for developing PCS real-time framework of China Fusion Engineering Test Reactor (CFETR). For such huge device, efficient plasma operation and safety is essential. Thus, the complicated PCS needs to be tested to verify the reliability, robustness and availability before plasma operation. This paper proposed an offline simulation module based on JRTF to validate the PCS. OOP technology and flexible configuration using XML files contributes a lot to flexibility and the reusability of the offline simulation module. In the paper, the PCS of J-TEXT tokamak is briefly introduced and analyzed. Then, the conception design of creating offline simulation module’s model is presented. In this section, we introduce a module to simulate the input data through history log and experiment data. The output is record by a simulated output module. Under such circumstance, the program is the same with the online program and only small changes in XML configure files is needed to import such offline simulation modules instead of real hardware I/O modules of reflective memory modules. In addition, a test in vertical field control system is conducted to proving the availability of offline simulation module of J-TEXT Real-Time Framework, an online experiment result has been compared with the offline simulation. Then, a test in horizon field control system is carried out in order to confirm the reusability of the offline simulation module. Also, a Simulink module converter has been developed. It can convert a Simulink designed module into a JRTF offline simulation module, which dynamically generates data based on Simulink designed models instead of using historical data.
