There are more than 50 types of transmission lines in use, with even more in the R&D stage. The goals are reductions in line loss and line faults and greater overall grid reliability and efficiency. An increasing number of transmission line applications incorporate high-temperature superconducting technologies. New types of composite conductors are being developed to retain their strength and be more resistant to degradation at high temperatures. What’s more, this sector is seeing some exciting new wide-area management systems (WAMS) and other applications built on top of data from synchrophasors. Some are even proposing an “air traffic control system” for the national grid. Keep up to date with changing transmission technologies by scrolling down.

American Superconductor Corporation (NASDAQ: AMSC), a global power technologies company, today announced that Vestas Australian Wind Technology Pty Ltd has placed an order with AMSC for a large D-VAR-based grid interconnection system. Utilizing 24 D-VAR modules integrated with external smart-switched capacitor banks and proprietary AMSC controls that are optimized for wind farm applications, this is AMSC’s largest order for a grid interconnection system to date. The solution will be utilized to meet local grid interconnection requirements for the 206 megawatt (MW) Collgar Wind Farm under construction in Western Australia. AMSC expects to deliver the D-VAR equipment to Vestas within approximately 12 months. AMSC’s grid interconnection solutions are already connecting more than one-third of Australia’s wind power to the power grid. |

Electric utilities have pursued devices that can limit fault current levels in transmission and distribution systems while remaining “electrically invisible” under nominal conditions. These fault current limiters (FCLs) have the potential to significantly alleviate power system stress in locations where fault current magnitudes are expected to increase beyond the duty of existing circuit breakers. Today’s superconducting materials can meet the performance requirements of power system components. As a result, a significant portion of proposed FCL designs use superconducting materials to achieve the limiting action. This report investigates the current status of these superconducting fault current limiter (SFCL) technologies and describes ongoing efforts to use them in electric power grids. |
