Abridgment of large hydroelectric generators: The trend in design and capacity

Abstract

The paper describes recent developments in design of large hydroelectric generators. New features of mechanical construction made possible by fabricated designs are particularly emphasized and illustrations of some recent machines given. The 77,500-kv-a. generators for the Dneprostroy Project in Russia, (which will be the world's largest hydroelectric generators) are described. In conclusion, some of the future possibilities, such as outdoor machines and multi-speed designs, are discussed.
