一、水轮发电机1. 单机容量不断增大。随着制造技术的发展,近10年来投入运行的大容量发电机显著增多。伊泰普水电站的发电机单机容量为82.36万千伏安,是当前国外容量最大的水轮发电机。据最近资料报导,苏联正在设计单机容量135万千瓦的水电机组,计划装在西伯利亚地区的图鲁汉斯克水电站。但从现有运行经验表明,大容量机组的可用率并不高,如美国大古力第三电站的第19～24号机(单机容量60～70万千瓦)的早期可用率还不足50%。
First, the hydro-generator 1. Stand-alone capacity continues to increase. With the development of manufacturing technology, the number of large-capacity generators put into operation in the past 10 years has remarkably increased. Itaipu hydro generator generator stand-alone capacity of 823,600 kVA, is currently the largest foreign capacity of hydroelectric generators. According to recent data, the Soviet Union is designing a hydropower unit with a single unit capacity of 1.35 million kilowatts and plans to be installed at the Tulukosk Hydropower Station in Siberia. However, the existing operational experience shows that the availability of large-capacity units is not high, such as the United States Gugul third station No. 19 ~ 24 (stand-alone capacity of 60 to 700,000 kilowatts) early availability is less than 50% .
