某水电站技术供水系统优化

Optimization of the Technical Water Supply System for a Hydropower Station

通过分析某水电站机组技术供水系统的特点,其主要优点是有主设备冗余设计、二级减压设计、正反向供水设计以及安全设计等,但也暴露出一级减压阀无冗余的不足。经对系统以及其运行方式的研究探索,提出在不增加设备、合理利用现有设备的基础上,充分利用环境因素,采用两路减压供水一备一用的仅增加一级减压阀冗余的优化方案,提高了系统的安全可靠性。

The characteristics of the technical water supply system in a hydropower station are analyzed.It has certain advantages such as the redundancy of main equipment,two-stage pressure reduction,forward and reverse water supply and safety design.While no redundancy of the first-stage pressure reduction valve is provided.On the basis of no additional equipment and reasonable utilization of existing equipment,an optimization scheme is proposed,in which a one-stage pressure reduction routine and a two-stage pressure reduction routine are provided separately as the major and standby water supply.The reliability of the system is improved with this redundancy design.
