Preliminary implementation of plasma discharge simulation system based on ITER plasma control system simulation platform

The high-parameter stable plasma operation requires a more complicated discharge scenario and control scheme. In order to improve plasma discharge efficiency and reduce operational risks, exception handling methods should be fully evaluated before applying them to the plasma control system (PCS). A model-based plasma discharge simulation system has been implemented on the Plasma Control System Simulation Platform (PCSSP) to provide a simulation and test environment. This system replaces the real PCS organization and coordination algorithm with a plasma control simulator with algorithm integration and scheduling capability. At the same time, the exception simulation components are constructed to support the simulator's response to exception events. Be-sides, the data acquisition and processing module, scheduler module, and actuator module are constructed to assist the algorithm scenario testing. Then, the tokamak + plasma module is constructed in combination with the GSevolve model. In order to optimize the exception handling mechanism, this system has been applied to plasma discharge exception simulation.
