Some of those aspects of the auxiliary services in large power stations on which decisions have to be taken at the planning stage are discussed. The effects on the planning of auxiliary services of recent changes in generation practice are noted. The aspects discussed include alternative means of providing auxiliary power, the economic justification for providing standby for various auxiliary-plant items, the diagrammatic arrangement of auxiliary services, the economic and practical importance of certain basic design features and performance figures and sundry practical details that require thought at the planning stage. It is shown that decisions at this stage should be based as closely as available data permit on quantitative assessments. Among these, particular attention should be given to assessments of the reliability of individual plant items, of the cost of any measures such as duplication for increasing reliability, and of the total cost of forced outages. Methods of basing decisions on such assessments are given. On the basis of experience with a large number of power stations recommendations are made for obtaining the greatest possible ease of operation and maintenance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
