Title:
DIRECT-DRIVE COUNTER-ROTATING DOUBLE-WIND-WHEEL WIND TURBINE GENERATOR SET
Document Type and Number:
WIPO Patent Application WO/2022/110932
Kind Code:
A1
Abstract:
The direct-drive counter-rotating double-wind-wheel wind turbine generator set, comprising a double-rotor generator, and a front wind wheel (1) and a rear wind wheel (2) provided at two ends of the double-rotor generator in series by means of a front main shaft (3) and a rear main shaft (4). The double-rotor generator is sequentially provided with an outer rotor (14), an outer stator (15), a magnetic isolation layer (16), an inner stator (17), and an inner rotor (18) from outside to inside, the outer rotor (14) being sleeved on the outer stator (15), the outer stator (15) being sleeved on the inner stator (17), the magnetic isolation layer (16) being provided between the outer and inner stators, and the inner stator (17) being sleeved on the inner rotor (18). The structure, electromagnetism, and control of the dual-rotor generator having front and rear wind wheels are decoupled, thereby decoupling the front and rear wind wheels in operation and control and achieving independent control of the speed of the front and rear wind wheels, thus improving the overall efficiency of the generator set.
