American Hydroelectric Practice PDF Download

Excerpt from American Hydroelectric Practice: A Compilation of Useful Data and Information on the Design, Construction and Operation of Hydroelectric Systems From the Penstocks to Distribution Lines No attempt has been made to make this work a text-book on design in the sense that it should give the fundamentals on which the design and construction of parts of a hydroelectric system are based. It is, on the other hand, a compilation of the practical and essential features of design, construction and operation as worked out in many plants and systems, interpreted and arranged for convenient use and reference by plant designers, constructors and operating engineers. Unlike the usual handbook, it explains how certain results have been obtained under particular conditions and deals with the unusual as well as the general run of conditions in both construction and operation. To carry out the aim of the text, therefore, the authors have drawn liberally on published experiences and solutions of system problems and those features of plant layout essential to the subject matter treated. When the text is critically analyzed, apparent gaps may appear. For instance, the design and construction of dams and complicated station and large substation structures have been omitted. This has seemed advisable since these are specialized fields of engineering calling for particular and individual consideration by a specialist who need not be essentially an electrical engineer or operator and therefore outside the scope of this work. Likewise specifications for apparatus and details of equipment have been given only briefly, for the reason that the engineer who will find this book of value will be in possession of this information and will find the information recorded of greatest use as a guide in formulating, arranging and comparing plans and specifications, operating results and the like, with the actual results worked out in particular cases. The material in Chapters I, II, III and VI has been largely supplied by Mr. Taylor, interpreted and supplemented from his own experience in plant work. For a large part of the material in the remaining chapters the authors are indebted to the American engineering journals, which are credited throughout, particularly the Electrical World, from the columns of which descriptions of plants and results of system investigations and other data have been liberally drawn. Acknowledgment is especially given to L. N. Crichton of the Westing-house Electric and Manufacturing Company for the material on installation of protective relays in Chapter VI, which was taken with his permission from a most practical article by him in the Electric Journal.
