AI Technical Summary
In existing coaxial dual-rotor wind power generation systems, the diameters of the two rotors are similar, resulting in consistent cut-in wind speeds. This makes them unsuitable for low-wind-speed environments, and the interaction of wakes increases the difficulty of coordination, leading to low wind energy utilization.
By capturing low-speed wind energy through a small rotor, and using a deflector to accelerate the airflow to impact the tip of the large rotor blades, combined with tilt adjustment and power distribution control, the large rotor can start up at low wind speeds and optimize wind energy utilization at medium and high wind speeds.
It expands the effective operating wind speed range of the wind turbine, improves the wind energy utilization rate, and realizes the coordinated drive and power superposition output of the large and small turbines.
