Return to Session DEVELOPMENT AND DEMONSTRATION OF A LONG LENGTH TRANSMISSION VOLTAGE COLD DIELECTRIC SUPERCONDUCTING CABLE TO OPERATE IN THE LONG ISLAND POWER AUTHORITY GRID

چکیده
The US Department of Energy is funding the world’s first cold dielectric superconducting power cable demonstration project at transmission level voltage, to be installed at the Long Island Power Authority (LIPA) grid in 2007. The cable is designed to carry 574 MVA at a voltage of 138 kV. It will remain installed as a permanent part of the LIPA grid. The project team is comprised of American Superconductor, Nexans, Air Liquide and LIPA. This paper will give an overview of the technical goals of this project as well as the project status. It will describe the cable design and development process, the refrigeration system and the site installation status. An overview will be given about some system-specific operational characteristics influencing the cable system design such as fault currents.

High Temperature Superconductivity:Past, Present and Future
The superconductivity was discovered in 1911. In the same year, Sumitomo Electric Wire & Cable Works was established (Foundation was in 1897 as Sumitomo Copper Rolling Works), and laid the first Japan-made high-voltage underground cables. In 2011, we will celebrate the centennial anniversary of the discovery of superconductivity, and a high-temperature superconducting (HTS) power cable will be ...
متن کاملDemonstration of an optical interface for SFQ logic circuits
Single-flux-quantum (SFQ) logic circuits are expected to be operative at a clock rate above 100GHz with very low power consumption. A considerable amount of research has been performed on this topic, and noteworthy achievements, e. g. 120 GHz shift register [1] and microprocessor consists of over 10,000 junctions [2], have been reported recently. With the progress of the performance of SFQ circ...
متن کاملDevelopment of a Frequency-stabilizing Scheme for Integrating Wind Power Generation into a Small Island Grid
Integrating wind power generation into small islands has been one of the demonstration projects in Okinawa Prefecture, Japan. Since such integration could deteriorate power quality, including frequency, in an island grid, a frequency-stabilizing system using flywheels has been integrated into a small island. In order to establish a proper frequency-stabilizing scheme for a small island, an accu...

Abstract. In the recent gyrotron development in JT-60U ECRF system, output power of 1.5 MW for 1 s has been achieved at 110 GHz. It is the world highest power oscillation in the range of > 1 s. In addition to the carefully designed cavity and collector in view of thermal stress, an RF shield for the adjustment bellows, and a low-dielectric-loss DC break enabled this achievement. Power modulatio...
