【摘要】 10 MW高温气冷堆(HTR-10)的分散控制系统(DCS)执行对HTR-10的运行监测和控制功能。原DCS在设备可靠性、历史数据存储和转换等方面存在不足。根据HTR-10各工艺系统及控制对象的要求,分析了DCS的系统架构、功能和性能指标等;对I/O通道进行配置;提出以施耐德Quantum67160系列产品为主要模件的多重冗余硬件平台以及分别以UNITY和iFIX作为系统软件平台和组态工具的配置方案;采用PTO模块完成对棒控和装卸料系统控制,使用智能仪表对交流采样方案进行改进,在通信网络中加设逻辑网关的办法实现第三方通信功能。该设计方案可有效解决HTR-10原DCS存在的问题,满足HTR-10对DCS的要求。更多还原

【Abstract】 The distributed control system(DCS) of 10 MW High-Temperature Gas-cooled Reactor(HTR-10) takes charge of operation monitoring and control to HTR-10.The disadvantages of the original DCS at present such as reliability of facilities and history operation data system were introduced.Based on the requirements of technologic systems and control objects,the system architecture,functions and performances were analyzed.The I/O channels configuration was completed.The design scheme which was comprised of the multi-redundancy hardware flat based on Schnieder Quantum 67160 series products,the system software flat by UNITY and the configuration tool by iFIX were presented.The control rods and fuel handling control systems were driven by PTO modules.The AC sampling scheme was modified by adopting intelligent instrument.A specified logical gateway for third-party communication will be developed.The design scheme present in this article can solve the problems and match the demands from DCS of HTR-10.更多还原
