摘要
本文应用PIPENET软件对我国自主研发的三代压水堆核电厂二回路给水系统进行建模。利用瞬态计算功能模拟水锤发生及衰减过程,计算最大水锤压力、管系中最大水锤载荷以及最大水锤压力和载荷发生的时间及位置等。主要针对以下工况进行敏感性分析,即给水调节阀不同关闭特性、不同关闭时间、系统管径变化、阀门安装位置等对水锤的影响。
Through the application of PIPENET software,the model of China's independent research and development of the three generation of PWR nuclear power plant feedwater system is established.Water hammer calculation is simulated including Water hammer occurrence and the decay process by transient function,the maximum water hammer pressure in the pipe system,maximum water hammer load,and the maximum water hammer pressure and load time of occurrence and location is calculated.Sensitivity analysis of the water hammer is carried out according to the following conditions mainly,namely the feedwater regulating valve and feedwater isolation valve is closed,the different effect of different conditions of closing time,the change of diameter of the valve system,the installation position.
