Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1915 edition. Excerpt: ...experiMr. ence leads him to believe that it more frequently happens just the other ptau' way; that is, that the generator huilder has fixed conditions which, normally, cannot be met by the turbine builder. It is only a few years ago that the practice existed first to look for a standard generator which could be obtained at a favorable price--if not second-hand--and then force the turbine manufacturer to build a machine which would meet the sometimes very freakish requirements of power and speed. Even now a generator is often purchased with a fly-wheel effect of its rotor insufficient to secure satisfactory speed regulation of the unit, although, with little extra expense, such fly-wheel effect could be most efficiently built into the rotor without impairing the efficiency of the generator. A hydraulic prime mover, like no other prime mover, is dependent on the manifold characteristics of its operating fluid supplied by Nature. It is the head and flow which are fixed with each development; it is the quality of the. operating water, the climate, and many other factors which enter into consideration in the selection of the proper size and type of turbine; and it is natural that the specialist should know most about it, and therefore he should be given all the underlying data for deciding on the best selection. Under the heading "Load Factor" Mr. Galloway suggests operating the steam plant over the peak and raising the load factor on the hydroelectric plant. The writer invites attention to one phase of this condition: Suppose it costs more to produce a steam, or other than a waterpower, kilowatt, and suppose the water-power is combined with a storage reservoir; then it would seem to be more economical to let the water-power plant...show more
