Renewable energy sources have become an important part of the global energy portfolio, and thankfully this environmentally friendly trend shows no signs of stopping. As renewable energy sources continue to be more efficient and viable, AMSC continues to develop innovative technologies that serve their integration.

AMSC’s Renewable Interconnectivity Solutions allow wind and solar generation plants, no matter the size, to be able to meet strict voltage stability compliances imposed by regulators and utilities.

D-VAR® Systems

Ideal for meeting grid interconnection standards

Located at the wind or solar plant substation, our D-VAR system cost effectively provides the dynamic reactive VAR compensation that is essential to connect renewable power plants to the grid effectively and meet even the most stringent interconnection requirements.


In-turbine solution to improve ride-through ability

Located inside individual turbine towers, our patent-pending D-VAR RT system can be easily and cost effectively added to new turbines or retrofitted to existing turbines. It provides individual wind turbines with voltage control by dramatically improving the ability of the turbines to ride through power grid voltage disturbances that might otherwise interrupt operation.


Simplest and most cost effective LVRT retrofit option

Developed specifically to meet China’s grid codes, the Wind-RT retrofit system detects voltage dips on the power system and quickly (within 20 ms) isolates the turbine from the power grid. It then acts to precisely absorb the power generated by the wind turbine to maintain constant turbine speed and torque while providing reactive power to keep the turbine magnetized and at a constant voltage. Once the voltage recovers, the turbine is smoothly reconnected to the power grid, resulting in dramatically improved LVRT, more power generation and seamless wind energy grid integration.
