Goldwind launches turbine for ultra-low speed wind conditions

April 24, 2012

Xinjiang Goldwind Science Technology Co Ltd has launched a new 1.5-MW turbine optimized for ultra-low wind speed conditions. The GW93/1500 leverages Goldwind’s well-established 1.5-MW permanent magnet direct-drive with a 93-meter rotor diameter designed for IEC class S wind resource.

Although IEC class S is essentially the undefined “fag-end” of the wind spectrum, ultra-low wind speed areas are generally considered to have a low annual average wind speed of 5.5 m/s to 6.5 m/s.

As wind power technologies improve, the available resources in low wind speed and ultra-low wind speed areas have significant potential. Goldwind observes that there are also many ultra-low wind speed areas in close proximity to urban centers with strong grid capacity.

It claims its new turbine has the largest rotor diameter and the highest power generation efficiency among comparable products in China. According to its designed capacity, the GW93/1500 series can generate power of more than 2,000 standard hours per year based on an annual average wind speed of 5.5 m/s (with reference to the standard air density and Rayleigh distribution).
