摘　　要：采用数值模拟的方法,建立大规模快速加氢站的整体加注流程模拟分析模型,分析快速加注过程不同加注参数对列车储罐内氢气情况的影响特性。结果表明:三级压缩是最经济合理的压缩方式;当加注速度相差108 kg/h时,加注结束后储罐内氢气温度相差约5 K,与环境换热功率相差约20 kW;预冷温度对氢气温度和加注时间均有影响;当初始压力相差3/5 MPa时,加注时间相差约40/60 s。This study employs a numerical simulation method to establish a comprehensive simulation and analysis model for the fast refueling process at large-scale refueling stations for hydrogen trains.The investigation focuses on analyzing the influence of various refueling parameters on the hydrogen conditions within the train′s storage tank during the rapid refueling process.The findings reveal that a three-stage compression proves to be the most economically viable compression method.A discrepancy of 108 kg/h in the refueling rate results in an approximate 5 K difference in the hydrogen temperature within the storage tank post-refueling,along with an approximately 20 kW variance in heat exchange with the environment.Furthermore,the pre-cooling temperature is identified as a factor affecting hydrogen temperature and refueling time.In scenarios where the initial pressure varies by 3/5 MPa,the refueling time exhibits an approximate difference of 40/60 seconds.
