∶龙滩水电站安装7台700 MW混流式水轮机，具有转轮直径大、水头变幅大等特点，同时在电网中担任调频、调峰和事故备用，工况变化快、启动频繁，为确保安全稳定运行，提出了巨型转轮零缺陷运行维护的理念，并采取了一些必要的措施。自2007年5月首台机组投产发电以来，各台机组转轮缺陷得到了有效控制，实现了巨型转轮的零缺陷运行。
∶龍灘水電站安裝7檯700 MW混流式水輪機，具有轉輪直徑大、水頭變幅大等特點，同時在電網中擔任調頻、調峰和事故備用，工況變化快、啟動頻繁，為確保安全穩定運行，提齣瞭巨型轉輪零缺陷運行維護的理唸，併採取瞭一些必要的措施。自2007年5月首檯機組投產髮電以來，各檯機組轉輪缺陷得到瞭有效控製，實現瞭巨型轉輪的零缺陷運行。

There are 7 Francis turbines, with single unit capacity of 700MW, in Longtan hydropower station, which is characterized by large diameter runner and large variation in water head. The station requires frequent startup and frequent changes of operating conditions due to its peak regulation, frequency modulation and emergency backup functions in the power grid. In order to ensure safe and stable operation of unit, zero-defect operation concept is in-troduced and necessary measures are taken. Since the first unit put into operation in 2007, the failures due to runner defects were effectively controlled;besides, the large diameter runner achieved zero-defect operation target as well.
