基于数字化控制平台的核电站除氧器压力控制策略设计

DESIGN OF PRESSURE CONTROL STRATEGY FOR DEAERATOR IN NUCLEAR POWER STATION BASED ON DIGITALIZED CONTROL PLATFORM

结合在建核电机组普遍采用DCS作为控制系统平台的现状,基于数字化控制平台设计了适应核电站全运行过程的除氧器压力控制策略,并将其应用于DCS。相对于常规仪表控制系统,该控制策略具有较强的控制功能和人机优化特性。

Combined with the status quo of commonly adopting DCS as control system platform for nuclear power units under construction,the control strategy for deaerator suitable to whole operation process of the nuclear power station has been designed on the basis of digitalized control platform,and the said strategy being used to DCS.Compared with the conventional instrument control system,the above-mentioned control strategy boasts stronger control function and optimized behavior for man-machine comunication.
