摘　　要：基于ITER气体加料的功能需求,及面临ITER超长注入管线、强磁场、高辐照及涉氚的特殊运行工况,并遵循ITER仪控系统的设计框架,完成了气体加料运行控制系统的设计和仪控器件改进。并依据GIS终期设计方案构建试验平台,对系统气体加料特性进行试验研究。获得了系统响应时间等关键技术指标,同时验证了预过充策略对长管道气体输运响应时间的优化,以及采用载气模式实现快速杂质气体注入的有效性。Based on the functional requirements of the ITER gas injection system and considering the unique operating conditions of ITER,including ultra-long injection pipelines(>20 m),high magnetic fields,high radiation,and tritium involvement,the design of the gas injection operation control system was completed following the ITER plant instrumentation and control(I&C)design requirements.Additionally,improvements in instrumentation were implemented to account for the harsh environments.An experimental test platform simulating the final design specifications of the Gas Injection System(GIS)was constructed.Characterization of the gas injection dynamics was performed on this test platform and key technical parameters including system response time were obtained.The pre-filling method to optimize the response time for gas transport through long pipelines,and gas puffing with a carrier gas to enable rapid impurity gas injection,were experimentally verified.
