| 摘要: |
| 为提高增压锅炉装置降负荷速度, 改善动力系统机动性，提出一种可行的快速降负荷控制策略.分析增压锅炉装置降负荷特性，结合已有研究成果构建某型船用增压锅炉装置的机理模型，借助SimuWorks系统仿真平台搭建全系统模型，进行快速降负荷控制策略的仿真实验.结果表明：实验搭接的仿真模型可信度较高，与实际设备运行的误差在0.3%以内；该型增压锅炉装置匀速降负荷时，燃油流量调节阀的最大关阀速度为1.85 (°)/s，需要172 s才能重新回到稳定状态，而分段式降负荷控制策略耗时缩短43.78%，且分段数越多，回归稳定耗时越短.研究成果对该型增压锅炉装置的监控系统设计和调节阀参数设定有一定的指导意义.

| Abstract: |
| Abstract: A down-load control strategy for supercharged boiler installation is put forward, which can increase the boiler's down-load speed and improve maneuverability of power system. By the simulation platform named SimuWorks, the down-load characteristic is analyzed based on the mechanistic models of marine supercharged boiler installation. The simulation result shows that the model has a high credibility, the error between simulation model and actual equipment is under 0.3%. The max valve-closed speed is 1.85 (°)/s, and it takes boiler 172 s to return stable. Down-load by steps will shorten elapsed time at least 43.78% to return stable, and the more steps, the less time spends.
