摘　　要：针对某电厂循环水供水系统的特点,应用动态流体分析软件,对系统启泵水力过渡过程进行了计算机仿真,对不同工况启泵对应的过渡过程进行了比较分析,得出了较理想的启泵方式。仿真结果表明,正常启泵工况下,合理控制开阀规律,管道压力变化较小;事故停泵后重启工况下,系统压力波动较大,是启泵过程中需要注意的控制点。经仿真计算得出的结论对提高电厂循环水系统的可靠性和运行稳定性具有重大意义。In accordance with the characteristic of circular water supply system in the power plant, computer simulation was made on the transition process of pump-startup by applying the fluent analysis soft. Comparing the transition process corresponding to different pump startup methods and the perfect one was found out. The simulation results showed that reasonable starting valve regulation could result in small variation of water pressure when all the pumps started normally. Under the pumps stop and restart conditions, the range of pressure variation was big and this was the reference point in transient study. The conclusion had important practice significance to improve reliability and stability of circular water supply system in power plant.
