摘要 介绍了聚变堆主机关键系统综合研究设施(CRAFT)中负离子源中性束注入冷却水系统的初步设计以及热工水力分析,采用Flowmaster软件建立热工水力模型,采用PID控制实现精确的温度控制。仿真结果表明,温度、压降和温度控制精度满足供水温度150~200℃/温度精度±0.5℃的运行要求。研究结果将为NNBI冷却水系统热工水力分析和温度控制提供参考。 The preliminary design and thermal-hydraulic analysis of the Negative Neutral Beam Injection(NNBI)cooling water system in the Comprehensive Research Facility for Fusion Technology(CRAFT)is presented.The thermal-hydraulic model is established by Flowmaster software,and the precise temperature control is realized with Proportional-Integral-Differential(PID)control.The simulation results show that the temperature,pressure drop and temperature control accuracy meet the beam source constant temperature water supply system operation requirements that the water temperature is within 150~200℃with the control accuracy of 0.5℃.The results will provide reference for thermal and hydraulic analysis and temperature control of NNBI cooling water system.
