Four D-VAR® orders for wind farms on three continents

to meet dramatically varying grid interconnection requirements around the world. This ensures the quality of the power being delivered to customers and in many cases improves the reliability of the local power grid.” capacity increased 27% in 2007 to more than 94 gigawatts (GW), according to a Global Wind Energy Council (GWEC) report issued in April 2008. The global wind energy market, according to the report, is expected to grow an additional 155% to 240 GW of total installed capacity by 2012.

AMSC’s proprietary D-VAR systems enable wind farm developers to meet the national and provincial requirements adopted in many countries for connecting wind farms to power grids. AMSC customers utilise D-VAR grid interconnection solutions to provide voltage regulation and power factor correction, along with post-contingency assistance to prevent voltage collapse on the power grid. “Our D-VAR solutions are being used around the world to safely connect wind farms to electric power grids,” said Chuck Stankiewicz, executive vice president and general manager of AMSC Power Systems. “These solutions mitigate voltage instabilities at wind farms to enable wind farm owners and operators

American Superconductor Corporation (AMSC) has received orders for its D-VAR® solution for grid interconnection of wind farms located in Australia, Canada and the United Kingdom. The wind farms will utilise wind power systems from three different global wind turbine manufacturers. The D-VAR systems, which will provide voltage support for more than 200 megawatts (MW) of aggregated power, will be delivered to all four wind farms within the next 12 months. AMSC now has an installed base and orders for solutions to serve approximately 7,350 MW of wind power worldwide, an increase of more than 120% over the past year. Exhibited for the first time at wire 2008, COS 1200-37 the multi-wire concentric stranding line for screening of power cable, from Pourtier – Gauder Group. The machine has been designed to produce high quality round or sectoral compacted strands of 7, 19, 37 or 61 copper (1.5–3mm diameter) or aluminium (2 – 3.5mm diameter) wires. and multi-wire process permit speeds up to 500rpm (compared to 200rpm with a traditional rigid stranding line) while keeping a short line length. Moreover, each bobbin is equipped with an individual driven tension control for the prevention of wire breakage, optimisation of the final section and, therefore, resistance of the cable. A 37-wire line is composed of 6 independent modules of two reels of three wires each, individually motorised by AC motors. Filling of the reels is made from basket pay-offs with an individual capstan to pull the cable and to equalise the tension of each wire, reaching the best winding quality. Higher speed, smaller space, safer production, this flexible line also allows reduction of copper remainders, all the parameters being adjustable from the Colour Touch Screen Control Panel for a better process control.

Horizontal lead extruder Since the development of the new automatic and horizontal lead extruder in 2004, followed by the first commercial sale to Ducab in 2006, fourteen of the HFSAB units have been sold worldwide, eight of which have already been delivered and commissioned. The machine's automatic and accurate operation ensures a high quality, continuous production of cables, for weeks on end if required. The extruder is floor-standing with all components readily available for ease of maintenance and a considerable reduction in installation cost as a minimum of foundation work is required. At the end of May 2008, HFSAB moved in to new, purpose-built facilities. These facilities include in excess of 2,000m 2 assembly, warehousing and prototyping areas.
