摘　　要：针对大化水电站扩建工程机组技术供水的设计方案和投产运行后存在取水口、滤水器堵塞严重,技术供水满足不了机组对冷却水量、水压的要求,影响机组安全稳定运行问题,大化水电厂开展了分析研究,分析了导致堵塞的原因,提出了优化改进措施并实施了改造,改造后两年来的运行情况证明所做的改造行之有效,解决了影响机组稳定运行问题。对同类型水电站的技术供水系统设计、运行和维护具有一定的参考价值。Based on the problems, which endanger safe and stable operation of the units in Dahua hydropower ex- pansion project, such as blockage of intake and water filter, and the unsatisfied cooling water quantity and pressure of the uni4 the related improvement measures were put forward and put into practices. Through two years＇ running, it is proved that the improvement measures work very well, which can be referenced by the design, operation and main- tenance of technical water supply system of similar projects.
