2.5-MW inverter ready for wind power and photovoltaics

By Kathie Zipp | August 5, 2010

A 2.5-MW inverter (Generator control unit) is ready for use in large on and offshore wind turbines. The 2.5-MW inverter uses an IGBT-based design and delivers power to the grid from permanent magnet generators (PMG). A U.S.-based OEM is expected to deploy the unit in an offshore European multi-GW wind farm under development. The 2.5-MW design supports towers with a capacity of 5 to 6 MW, and future designs with capacities over 10 MW. Furthermore, the liquid-cooled inverter uses medium voltage to reduce a customer’s footprint and cabling costs. The units are available for production and compatible with a wide range of wind turbines. The 2.5 MW inverter features medium voltage, 5,500 Vdc, to lower cabling investment. Liquid-cooling provides an industry leading density (10W/in3.) and higher reliability. A high conversion efficiency (98.5% at full load) increases power delivery to the grid, enabling higher return on investment. A modular design permits flexibility in sizing multiple inverters for wind-power generators in excess of 10 MW. Low-output voltage harmonics distortion (THD <3%) provides higher power quality delivered to the utility grid. The inverter works with photovoltaic arrays as well.

    I am a senior mechanical engineering student working on a team designing a wind farm for Lake Champlain in Vermont. I was wondering how much heat the water cooling systems need to remove from these inverters and also what the price ranges for these 2.5MW inverters is.

    thanks for the help,
    Nathan Dierlam
