AMSC wins UK and US wind grid link contracts

UNITED STATES: AMSC has won two contracts to supply its voltage-stabilising technology for the grid connection of wind projects in the US and the UK.

AMSC has installed its D-VAR technology on a number of wind projects in the US

The company will install its dynamic volt-amp reactive (D-VAR) system in order to meet grid interconnection standards for safety and stability required for all renewable energy projects in the two countries.

In the US, AMSC will supply the system to connect the Route 66 wind project to the Electric Reliability Council of Texas (Ercot) grid. The project is near Amarillo, Texas, and is currently under construction. It will be owned and operated by wind developer First Wind.

Turbine manufacturer Senvion will also use AMSC's D-VAR system to connect the Strathy North wind project in Scotland to the grid. The development, which is owned by utility SSE, is currently under construction and will feature 33 Senvion MM82 2.3MW turbines.

Both systems are set to be installed by the end of the financial year, AMSC said.

The system detects and rapidly compensates for voltage disturbances by injecting leading or lagging (behind or ahead in phase) reactive power into the grid.
