Abstract

The invention discloses an ocean current energy integrated power generation device based on a magnetic flux modulation composite motor, which includes a low-speed rotor, a magnetic-regulation armature, and a high-speed rotor. Among them, the low-speed rotor is composed of guide vanes, low-speed rotor back iron and low-speed rotor permanent magnet; the field-adjusting armature is composed of field-regulating pole pieces and armature winding; the high-speed rotor is composed of high-speed rotor back iron and high-speed rotor permanent magnet. The field regulating armature is arranged between the high speed rotor and the low speed rotor, a first air gap is formed between the low speed rotor and the field regulating armature, and a second air gap is formed between the field regulating armature and the high speed rotor. The invention perfectly integrates the turbine, gear box and generator in the traditional ocean current power generation system, and adopts an integrated structure to realize energy capture and energy conversion. The power generation device has the advantages of compact structure, high conversion efficiency, and overload protection, and has high power density, no contact between input and output, reduced maintenance costs, low noise, and little pollution to the marine environment.

Description

technical field [0001] The invention relates to an ocean current energy integrated power generation device based on a magnetic flux modulation composite motor, belonging to the field of ocean current power generation. Background technique [0002] At present, the traditional ocean current power generation system uses water flow to drive the turbine to rotate. If the permanent magnet synchronous generator is used as the energy conversion component for such low-speed rotation, the motor will be bulky. In order to reduce the system volume, the usual method is to combine the turbine with the permanent A mechanical gearbox is installed between the synchronous generators. Relying on mechanical gears to increase the low-speed rotation of the turbine blades to high-speed motion, the volume of the matching permanent magnet synchronous generator can be appropriately reduced. Traditional ocean current power generation systems use turbines for energy capture, mechanical gears for speed...
