【摘要】 采用U型管蒸汽发生器动态特性分析数学模型,研制开发了核电站蒸汽发生器实时仿真系统。该系统与控制系统形成能够相互作用的闭环系统,用于为核电站数字化仪表与控制(I&C)开发提供仿真对象及进一步控制方案研究。运用该系统对蒸汽发生器变工况进行了计算,所得结果与核电站仿真机的计算结果符合较好,为核电站仪表与控制(I&C)系统数字化开发提供了理论依据。更多还原

【Abstract】 The real-time simulation system, which forms a interactive closed circle together with the steam generator control system, has been developed using a dynamic mathematical model of steam generator in this paper. It can provide a simulation target for upgrades of digital Instrument & Control system in Nuclear Power Plant (NPP) and is applicable for further research of control schemes. With this program, the authors have studied and analyzed the response of transient parameters to some different disturbance, the calculated results are in good agreement with those calculated by NPP simulator program. This will give a theoretical analysis for upgrades of digital I & C system in nuclear power plant.更多还原
