Applying supercapacitor modules in wind turbine pitch control systems, supercapacitors can still discharge high currents at temperatures ranging from -40 ℃ to+85 ℃, making them suitable for outdoor environments with different temperatures in the north and south; Fans are often located at high altitudes in the wild, making maintenance inconvenient. The lifespan of supercapacitors is much longer than that of batteries, which eliminates many maintenance costs for customers.
