| telecommunications power systems: DC Power System Design for Telecommunications Whitham D. Reeve, 2006-10-25 Straightforward, systematic approach for designing reliable dc power systems for telecommunications Here is a must-have resource for anyone responsible for designing, installing, and maintaining telecommunications systems. The text explains how to design direct current (dc) power systems that operate at nominal voltages of 24 and 48 volts dc, use lead-acid batteries, and are installed in public network telecommunications systems and other exclusive-use environments. Rather than train readers to design systems by rote, the author gives readers the skills and knowledge to perform systematic analyses to make the best choices based on several economic, operational, electrical, and physical considerations. Written in a straightforward style that avoids unnecessary jargon and complex mathematics, the text covers all the essentials of dc power systems for telecommunications: * Detailed descriptions of the seven major system components: Rectifier/charger System, Battery System, Charge Bus, Discharge Bus, Primary Distribution System, Secondary Distribution System, and Voltage Conversion System * Detailed descriptions include design equations, reference tables, block diagrams, and schematics * Design procedures to help readers select the most appropriate power system elements, such as buses, wiring, overcurrent protection, rectifiers, and batteries * Application of the American National Standards Institute's telecommunications industry standards and other relevant standards, practices, and codes * Strategies for dealing with voltage drop in distribution and battery circuits as well as guidance for sizing circuit wiring to meet voltage drop and current rating requirements * In-depth discussions that focus on the types of lead-acid batteries used in telecommunications and their applications Throughout the text, examples demonstrate how theory is applied to real-world telecommunications systems. Some 330 illustrations and more than 100 tables are also provided to help readers visualize and better understand complex systems. Design and application examples and accompanying solutions help readers understand the design process and use their new skills. In summary, engineers and technicians in the telecommunications industry will find all the resources they need to design reliable dc power systems. |

| telecommunications power systems: Terrorism and the Electric Power Delivery System National Research Council, Division on Engineering and Physical Sciences, Board on Energy and Environmental Systems, Committee on Enhancing the Robustness and Resilience of Future Electrical Transmission and Distribution in the United States to Terrorist Attack, 2012-11-25 The electric power delivery system that carries electricity from large central generators to customers could be severely damaged by a small number of well-informed attackers. The system is inherently vulnerable because transmission lines may span hundreds of miles, and many key facilities are unguarded. This vulnerability is exacerbated by the fact that the power grid, most of which was originally designed to meet the needs of individual vertically integrated utilities, is being used to move power between regions to support the needs of competitive markets for power generation. Primarily because of ambiguities introduced as a result of recent restricting the of the industry and cost pressures from consumers and regulators, investment to strengthen and upgrade the grid has lagged, with the result that many parts of the bulk high-voltage system are heavily stressed. Electric systems are not designed to withstand or quickly recover from damage inflicted simultaneously on multiple components. Such an attack could be carried out by knowledgeable attackers with little risk of detection or interdiction. Further well-planned and coordinated attacks by terrorists could leave the electric power system in a large region of the country at least partially disabled for a very long time. Although there are many examples of terrorist and military attacks on power systems elsewhere in the world, at the time of this study international terrorists have shown limited interest in attacking the U.S. power grid. However, that should not be a basis for complacency. Because all parts of the economy, as well as human health and welfare, depend on electricity, the results could be devastating. Terrorism and the Electric Power Delivery System focuses on measures that could make the power delivery system less vulnerable to attacks, restore power faster after an attack, and make critical services less vulnerable while the delivery of conventional electric power has been disrupted. |
