A study on the transmission power in dynamic contactless power transmission
2016 IEEE International Conference on Industrial Technology (ICIT), 2016In this study, the contactless power transmission system to supply intermittent power to the railway vehicle equipped with energy storage device is assumed. The maintenance cost reduction is expected compared to line-pantograph charging method. In order to reduce the amount of energy storage device and loss in the converters, the combination of static ...

Underground Power Transmission
Science, 1970Much of the generating capacity to meet the needs of the future may be from generating stations in groups of two or three, each of 1000 Mw, located away from the growing urban areas. Transmission systems will become longer and be of higher duty; and a combination of popular demand and land cost will force the system underground at increasing distances ...

Superconducting Power Transmission
Cryogenics, 1971At the present time it is predicted that the electric utilities will need to double their capacity every ten years. This rate of growth, about 8% per year, is not in itself awe-inspiring until one considers the present size of the electric industry. The estimated demand in the United States for the year 1990 is in excess of 109 kW.

Automatic Transmission of Power Readings
Transactions of the American Institute of Electrical Engineers, 1924The need of infornmation at one point as to power conditions in large systems for load dispatching, billing, or other purposes has led to the development of various methods of transmitting power readings over long distances. The development of superpower emphasizes this need and the perfection of means of communicating complete information as to power ...

Novel transmission power selection method in transmission power control
2010 3rd IEEE International Conference on Broadband Network and Multimedia Technology (IC-BNMT), 2010Transmission power control (TPC) has been studied as communication technique for reducing energy consumption in wireless sensor network. Most of all TPC algorithms have an inherent problem such as packet loss, retransmission, because it have been considered only sensitivity.

SDM for Power Efficient Transmission
Optical Fiber Communication Conference, 2017We discuss the principles behind the use of space division multiplexing for power efficient transmission in optical fiber communication systems. Experimental demonstration of these principles are realized in a multicore fiber transmission system.

Power Limitations of Transmission Systems
Transactions of the American Institute of Electrical Engineers, 1924Several independent studies have been made recently to determine the economies of a large, uniform power system. The two studies of more general interest were those conducted by the Department of the Interior, under the direction of W. S. Murray, for the Superpower Zone, and by F. G. Baum for the United States.

Electronic Stabilizer for Power Transmission
Transactions of the American Institute of Electrical Engineers, 1947Voltage regulation of an alternator historically has depended upon variation of the field current, and high-speed regulators have been developed in order to improve synchronous stability. This paper describes a voltage control brought about by varying the output current. A reactive load is connected to the generator terminals.
