摘要

以供汽系统为研究对象，采用集总参数法建立相应的数学模型，进行充汽阀自动控制充汽和旁通阀自动控制充汽两种充汽方式的动态仿真。结果表明：旁通阀自动控制充汽时完成3次充放汽时间为76.3 s，充汽阀自动控制充汽时完成3次充放汽时间为62.9 s，充汽阀自动控制充汽时平均每次充汽时间减少4.5 s；两种充汽方式关键参数在充汽阶段均维持较为稳定，在阀门切换阶段存在较大波动，但压力波动均小于0.2 MPa；相同充汽方式下，汽包压力波动< 过热蒸汽压力波动< 供汽母管压力波动。

Abstract

With steam supplying system as the object of the research

the mathematical models are based on the lumped parameter theory. The study has been carried out in two different charging ways. One of them is charging valve in Auto-Control and the other is bypass valve in Auto-Control. The simulation results show as follows.The time to complete three times charging and discharging is 76.3 seconds when bypass valve is in Auto-Control. The time to complete three times charging and discharging is 62.9 seconds when charging valve is in Auto-Control. 4.5 seconds have been saved for each charging when charging valve is in Auto-Control. The key parameters maintain relatively stable during the charging period in both charging ways. The main parameters have relatively larger fluctuations when the two valves are being switched on. But the main parameters are less than 0.2 MPa. In the same charging way

the fluctuation of drum pressure is less than the fluctuation of superheated steam pressure

and the fluctuation of superheated steam pressure is less than the fluctuation of steam supplying pipe pressure.
