AI Technical Summary
Existing wind turbines suffer from problems such as complex structure, high failure rate, high maintenance cost, difficulty in starting at low wind speeds, complex control required at high wind speeds, overload protection relying on pitch or braking, and the failure to effectively reuse the three-electric systems of retired electric vehicles.
The dual-rotor system with a fixed planetary carrier includes lift-type and lift-drag composite rotors. It achieves reverse rotation coupling through a planetary gear mechanism. Combined with load and control circuits and overload protection units, it utilizes aerodynamic characteristics for adaptive overload protection, eliminating the need for pitch and yaw systems.
It achieves adaptive optimization of the operating point over a wide wind speed range, simplifies the structure, reduces maintenance costs, improves reliability, enhances energy capture capabilities, reduces resource waste, and adapts to efficient power generation under different wind speed conditions.
