文章从二次密闭循环冷却供水系统、一次冷却供排水系统的主要设备选型计算等方面介绍单元二次密闭循环冷却供水方式。其中重点介绍二次密闭循环冷却供水系统关键设备（加压泵、膨胀罐）的选型计算。加纳布维水电站技术供水系统采用单元二次密闭循环冷却供水方式（单元供水是相对于集中供水而言，即每台机设置1套独立的供水系统）。经过实际运行，运行状况良好。
文章從二次密閉循環冷卻供水繫統、一次冷卻供排水繫統的主要設備選型計算等方麵介紹單元二次密閉循環冷卻供水方式。其中重點介紹二次密閉循環冷卻供水繫統關鍵設備（加壓泵、膨脹罐）的選型計算。加納佈維水電站技術供水繫統採用單元二次密閉循環冷卻供水方式（單元供水是相對于集中供水而言，即每檯機設置1套獨立的供水繫統）。經過實際運行，運行狀況良好。

The unit-based secondary closed circulating water supply means is described in terms of calculation of type selection of main equipment of the secondary closed circulating water supply system and the first cooling water supply/discharge system.Especially, calcu-lation of type selection of the main equipment (such as booster pump, expansion tank) of the secondary closed circulating water supply system is stressed.The unit-based secondary closed circulating water supply system is applied by Bui Hydropower Project.Through the practical operation, the system works smoothly.The unit water supply is specified in comparison with the central water supply system. Namely, one independent water supply system is provided to one turbine-generator unit separately.
