The First Batch of Megawatt Level Blade Power Enhancement Project for High-altitude Wind Power in China

         Jinfeng Technology has built the first batch of megawatt level blade power enhancement project for high-altitude wind power in China, combining multiple reliable guarantee technologies and advanced leading edge biomimetic small wing design high-tech achievements. While significantly increasing the swept area of the impeller, it effectively reduces the vortex loss at the blade tip. On the basis of ensuring the safe operation of the wind turbine, it has increased the annual equivalent hours of the technically modified units by an average of 6%, and 45 units can increase their power generation by a total of 8.1 million kWh per year, Realize increased power and efficiency.
