News International-French

4 May 2012

Xinjiang Goldwind Science & Technology Co., Ltd. announced the launch of its GW93/1500 ultra-low wind speed permanent magnet direct-drive (“PMDD”) turbine. The Group’s latest R&D achievement leverages its well-established 1.5MW PMDD turbine platform as the foundation for a new series with power generation efficiency that is among the highest in the industry.

The GW93/1500 ultra-low wind speed PMDD turbine has a 93-meter rotor diameter with a rated capacity of 1.5MW. It is designed for IEC class S wind resource areas where the annual average wind speed is lower than 6.5 m/s. The wind turbine has the largest rotor diameter and the highest power generation efficiency among comparable products in China. These characteristics will enable Goldwind to maximize the value that it offers to its customers.

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). The product will be officially launched in Xi’an, Shan Xi on April 20 and the Company plans to install its first prototype in Zhucheng, Shandong at the end of this month.

Goldwind’s GW93/1500 PMDD turbine uses a permanent magnet generator and a full-power converter with grid friendly properties. The turbine meets national grid connection requirements and meets zero voltage ride-through standards.

Ultra-low wind speed areas 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. There are also many ultra-low wind speed areas in close proximity to urban with strong grid capacity.

Goldwind seeks to maximize value for its customers. With its strong global R&D platform and innovative technologies, Goldwind has developed customized wind turbine series to accommodate diverse operating environments. In addition to the ultra-low wind speed series, Goldwind offers low wind speed, high altitude, low temperature, high temperature, offshore and tidal PMDD series. Goldwind has utilized these specialized series in several projects overseas including a high altitude project in Ecuador, a low wind-speed project in Chile, a high temperature project in Pakistan and a low temperature project in Minnesota, USA.

Customers from around the world have recognized Goldwind’s PMDD wind turbines many advantages, including low maintenance requirements, strong low voltage ride-through capability, high availability rate and high power generation efficiency.
