NEW DESIGN OF LARGE GENERATORS.

If electricity load growth until the end of the century averages 55 there may well be economic advantages in the use of larger unit sizes than those at present in operation or under consideration. These advantages arise mainly from the overall capital and operating cost savings, but they have to be balanced against the magnitude of development programs, reliability, etc. The article discusses the future prospects for generators with outputs substantially greater than 1300 Mw on the assumption that they will be required early in the next century and that the method of energy conversion will be through some form of fluid cycle with a turbine producing mechanical power, in more or less the same way as it has been for the last 80 years.
