摘　　要：介绍了发电机定冷水系统的构成。针对某电厂一起600 MW机组发电机定冷水系统定冷水流量突降故障,分析发生故障的原因为供水管路锥形滤网堵塞,根据机组实际情况增设一路辅助管路,并对新增设辅助管路的投运操作及投运后注意事项进行了分析总结,通过发电机定冷水管路改造,有效降低了主管路设备堵塞对冷却水供水的影响,提升了定冷水系统运行可靠性。The composition of generator stator cooling water system is introduced in this article. It provides an analysis of a low flow event for 600 MW generator stator cooling water system caused by filter clogging, and introduces the dealing process through making a system transformation. By add an auxiliary line, it enhances the reliability of generator stator cooling water system effectively.
