Power India found that Chinese wind turbine manufacturer Xinjiang Goldwind Science & Technology Co., Ltd. (Goldwind) has launched its new wind turbine GW93/1500 (1.5 MW) which has been designed specially for “ultra-low” wind speed sites such as available in India etc.
The new turbine is having rated capacity of 1.5 MW and rotor diameter of 93 m (larget among the comparable products in China as claimed by Goldwind) equipped with permanent magnet direct drive (PMDD) technology.
Some of the special features as captured by Power India are:
- The turbine is of IEC Class V
- Which means the turbine is capable to generate power at the sites having wind speed in the range of 5.5 m/s to 6.5 m/s
- The 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.
- 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 is the latest turbine developer to tap into the low wind speed turbine market, which is growing rapidly, as high wind speed sites, particularly in India and Europe, are set to become increasingly scarce, and developers look to exploit low wind speed sites close to highly populated areas.
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.
