摘　　要：为了满足舰船机动性和直流蒸汽发生器结构特点对给水调节精度的高要求,船用动力装置采用了大-小给水调节阀并联配置的方式。基于大-小给水调节阀的配置和蒸汽过热度模型,本文给出蒸汽过热度的控制系统架构,提出了分程切换控制、开度分解切换控制2种策略。最后采用工程算例对本文提出的控制方法进行了有效性验证,仿真结果表明分程控制方法满足船用动力装置要求。In order to meet the high requirements of ship's maneuverability and structural characteristics of once-through steam generator for feed-water control accuracy,the marine power plant adopts the parallel configuration of large and small feed valves.Based on the configuration and steam superheat model,this paper presents control system architecture of steam superheat,and proposes two strategies:split-range switching control and opening degree decomposition switching control.Finally,an engineering example is used to verify the effectiveness of the control method proposed in this paper.The simulation results show that split-range control meets the requirements of marine power plants.
