Helping Customers to expand market segmentation with customized design
Xinjiang Goldwind Science & Technology Co., Ltd., announced that it has completed the construction of its first large-scale high altitude wind farm project, which consists of 33 1.5MW Permanent Magnet Direct Drive (PMDD) turbines with a total capacity of 49.5MW. This is another showcase of Goldwind's objective to find and create value for customers, as well as its strong R&D capability.
The project is located at Yunnan-Guizhou Plateau, the mountain area in southwest Mouding county, Chuxiong, Yunnan province. The wind farm is situated at 2000 to 2500 metres above sea level. According to specific geographic and climatic features, the GW82/1500 and GW77/1500 high altitude wind turbines were selected for the project.
In April this year, Goldwind's first two high altitude 1.5 MW prototypes were successfully connected to the grid in Xi Tie Mountains of Qinghai Province and became operational. They have since maintained an impressive average availability rate of over 98.5%. According to the estimation based on a measured power curve, each unit can annually generate 2.8 million kWh, with an air density of 0.88 kg/m3 and an average wind speed of 6.5 m/s.
Goldwind's high altitude wind turbines are customized for high altitude northwest and southwest regions where wind power is largely undeveloped. The turbines feature advanced technologies including larger blades, enhanced thermal insulation, and strengthened protection against lightning and radiation to withstand conditions of low air density, frequent strikes by lightning, strong radiation from the sun, and other challenging conditions of high altitude areas.
Goldwind is China's first wind turbine manufacturer to develop low wind speed and high altitude wind turbines. It has already started the mass production of its PMDD low wind-speed, high altitude, low temperature and high-temperature series, and launched the offshore as well as tidal series with mass production capabilities.
Goldwind's PMDD wind turbines are welcomed and recognized by clients for its low maintenance cost, strong low-voltage ride-through capability, high availability rate and high power generation efficiency.
Goldwind is the world's largest PMDD wind turbine manufacturer and a leading comprehensive wind power solutions provider that develops, manufactures and sells wind turbines; provides "one-stop" services; and invests and develops wind farms.
