China Power News - June 6, the world's highest altitude wind farm - Zhegu distributed wind power project Dongfang Wind 2.X-131 permanent magnetic direct-drive wind turbine has been successfully hoisting, the position is 5,060 meters above sea level, the hub center of the unit is 5,150 meters above sea level, is the highest altitude wind turbine installed in the world. It is understood that the east wind power 2. X - 131 wind turbines with completely independent intellectual property rights, the capacity of 2.0 mw to 2.5 mw, adjustable impeller diameter of 131 meters, is suitable for below 5500 meters and high altitude area, adopting direct drive permanent magnet + full power converter technology route, with a small crew fatigue load, high reliability, high efficiency, etc. In view of the factors such as the decrease of air pressure and density in the ultra-high altitude area and the large daily temperature difference, Dongfang Wind Power 2.X-131 unit has applied a number of innovative technologies, adopted the self-developed "Wind Energy Intelligent Selection" digital platform and Oriental Intelligent Operation and maintenance system, etc., to fully reduce the cost per kilowatt hour of the project in the whole life cycle.

The unit adopts mature and reliable electrical main circuit topology, customized design of insulation structure, temperature rise, voltage resistance, etc. A self-developed electronic control system based on HIL-STS in loop co-simulation is equipped. The blade adopts airfoil optimization technology based on Reynolds number and aerodynamic power enhancement technology. Adopts the overshoot technology based on low temperature power increment algorithm, and the whole machine lightning protection dynamic simulation technology, integrated heat dissipation technology, integrated automatic lubrication technology. The unit can also be equipped with IPACOM wind power intelligence system based on edge computing, intelligent algorithm and other advanced technologies, which can better meet the needs of ultra-high altitude units in Xizang.
