摘要
以某新型船用蒸汽动力装置增压锅炉水位系统为对象,从增压锅炉水位系统数学模型的类型和特点出发,通过选择合适的建模方法,着重建立了汽水循环系统各模块动态数学模型。仿真结果表明:主机负荷变化引起的锅炉压力变化是导致虚假水位产生的最重要原因之一。
The water system of supercharged boiler which is used in a new type of marine steam power plant was studied.Based on the types and features of water system mathematical model,the dynamic mathematical model of soda circulation system module was established by selecting the suitable model building method.Simulation results showed that the fluctuation of boiler pressure caused by the main engine load is one of the most important reasons which led to false water.
