Sinopsis
Excerpt from Constant-Voltage Transmission: A Discussion of the Use of Synchronous Motors for Eliminating Variation in Voltage in Electric Power Systems
The new system of constant-voltage transmission has been successfully applied to both large and small power projects, and the results thereby obtained demonstrate convincingly that this method must be closely in vestigated by those responsible for the management or design of electric-power projects. The advantages of synchronous motors for raising the power-factor of the load of a steam-driven station have been thoroughly de scribed. It is, however, not so well known that synchro nous motors are of far greater value with long-distance transmission systems than with local power systems, so much so, in fact, that synchronous motors can often be installed to run idle, and yet save several times their cost.

Excerpt from Constant-Voltage Transmission: A Discussion of the Use of Synchronous Motors for Eliminating Variation in Voltage in Electric Power Systems
The advantages of constant-voltage transmission, in improved operation and lower cost, have been recently proved by actual examples, among them that of the longest transmission line yet built. The practical success of the method justifies the statement that the use of synchronous motors has been far too limited in the past.
It is the purpose of this book to urge that more synchronous motors be installed in alternating-current power systems, and that dependence be placed on them to secure the desirable results of controlling the voltage of lines at the opposite end to that of usual practice, and of more than doubling the power load of most lines. In this way, the installation of comparatively inexpensive machines can take the place of building entire duplicate transmission lines.
The decision regarding such important changes in design and operation, even when the examples described are kept in view, must be made according to thorough predeterminations of cost and operating characteristics. Working formulas, with examples, are given for these comparatively new calculations.
Although the writer is in favor of the increasing use of the principles of constant-voltage transmission, both in long-distance work and local distribution, he has tried to show impartially both sides of the case, and to outline the conditions where the new method is not applicable.

Paperback. Condición: New. Print on Demand. This book argues that synchronous motors are underutilized in power systems and that their use in constant-voltage transmission can improve transmission efficiency while reducing costs. Historically, electrical engineers sought to reduce energy loss from voltage variation through higher voltages at transmission lines' termini. However, this approach is costly due to the increasingly expensive terminals required. The author shows how synchronous motors can correct for voltage variation, allowing for lower voltage at the transmission line's end, which reduces costs and improves overall efficiency. The book provides a historical context for this method, showing that voltage variation correction via synchronous motors has been attempted in the past. The author contends that only recently have the full benefits of this approach been understood. By demonstrating how to extend the capacity of transmission lines and reduce overall construction costs, this book will appeal to professionals in the field of electrical engineering. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Nº de ref. del artículo: 9781330324202_0
