2009年1月6日 · The electric transmission network is the backbone of an electric system and carries electric power at a high voltage (from 115 kV up to 500 kV) over long distances. The transmission of electric power at a high voltage reduces the electricity losses allowing large volumes of power to be transported over long distances in an efficient manner.

2015年9月17日 · The foundation of modern electric power transmission was laid in 1882 when Thomas A. Edison's Pearl Street Station, a dc generator and radial line transmission system used primarily for lighting, was built in New York City. The development of ac transmission in the United States began in 1885, when George Westinghouse bought the patents for ac ...

2012年7月31日 · The electric transmission network is the backbone of an electric system and carries electric power at a high voltage (from 115 kV up to 500 kV) over long distances. The transmission of electric power at a high voltage reduces the electricity losses allowing large volumes of power to be transported over long distances in an efficient manner.

2012年12月1日 · This article reviews the actual status and the advantages and disadvantage of AC and DC transmission systems. UHVDC links are actually the most effective solution to transfer bulk power over distances of 1000 km or more. Submarine cables for HVDC applications are only available up to 500 kV. Self-commutated voltage source converters (VSCs) (especially IGBTs) …

2003年8月14日 · Overhead line or underground cable for transmission of electric power between points of electrical systems. Transmission line carrier. Communications system that uses a phase conductor or overhead ground wire on an electric power transmission line to transfer high-frequency signals. Ultrahigh voltage (UHV) Transmission voltage of 1000 kV and above.

2018年1月1日 · Modern electric power system consists of complex interconnected network of components generally divided into generation, transmission, distribution, and load. The invention of the transformer at the end of the nineteenth century enables electric energy to be transmitted at higher voltages and hence higher capacity.

2018年10月1日 · At present, China has several UHV power transmission lines in operation, and is the world leader in the development and deployment of grid technology, particularly UHVDC technology. The country has deployed an extensive network to integrate their massive RES portfolio and, in a few years, plans to build at least 13–20 new UHVDC lines.

1999年3月1日 · Electric-power transmission and distribution lines have been in use for about 100 years [1]. Since about 1970, significant concerns have arisen that the electric and magnetic fields from power lines and other sources might be affecting the health of exposed individuals. Prior to about 1982, electric fields were the main concern.

2010年11月1日 · China's electric power industry was started at the end of the 19th century [1]. Since 1949, the time when the People's Republic of China was established, this industry has been growing very fast. By the end of the 20th century, the total generating capacity of China's power industry was already placed second in the world.

2011年1月1日 · Modern electric power system consists of complex interconnected network of components generally divided into generation, transmission, distribution, and load. The invention of the transformer at the end of the nineteenth century enables electrical energy to be transmitted at higher voltages and hence higher capacity.
