The 1.5MW turbine, with a 93-metre rotor diameter, uses a permanent magnet generator and a full-power converter.

It is designed for class-IV wind resource areas where the annual average wind speed ranges from 5.5-6.5m/s.

According to Goldwind, the GW93/1500 series can generate power of more than 2,000 standard hours per year based on an annual average wind speed of 5.5m/s (with reference to the standard air density and Rayleigh distribution).

Goldwind plans to install its first prototype in Zhucheng, east China’s Shandong province at the end of this month.

The low wind-speed and ultra-low wind-speed areas, totalling 68% of China’s wind-resource areas, are normally in close proximity to urban areas with strong grid capacity.

China will have 20GW wind turbines installed in low wind-speed areas, out of the 100GW target for 2015. Sinovel said it is able to mass produce SL1500/81 and SL1500/89 low wind-speed turbines.

In January, Vestas received its first 27 units of V100-1.8MW turbine order from a low-wind site of Datang Hubei Renewable Energy in central China.
