The invention discloses a vortex-induced vibration-based power generation system, which relates to the field of wind power generation systems and comprises an external protection module, a kinetic energy collection module, an electric energy conversion module and an electric energy stabilization module, the vortex-induced vibration principle is utilized, kinetic energy of vortexes generated after wind blows through an entity is absorbed through resonance, and after the energy is absorbed, the electric energy conversion module converts mechanical energy stored by the kinetic energy collection module through electromagnetic conversion; the mechanical energy can drive a conductor in a closed loop to do magnetic induction line cutting motion in a magnetic field, and the part of mechanical energy in the action of continuously cutting magnetic induction lines is converted into alternating current; and after the electric energy stabilization module performs a series of operations such as rectification, filtering, voltage stabilization and inversion, the current can be converted into stable alternating current which can be directly utilized, so that the defects of traditional power generation are overcome, the maintenance is simple, tiny wind energy which is rarely utilized by traditional wind power generation can be utilized, and continuous power generation is realized.

Description

technical field [0001] The present invention relates to the technical field of wind power generation systems, in particular to a power generation system based on vortex-induced vibration. Background technique [0002] Northeast my country, North China and Northwest China all have extremely rich wind energy resources. Among them, the wind energy can be used for more than 5000 hours. There are two main types of devices for converting wind into mechanical energy: horizontal axis generators and vertical axis generators. [0003] A horizontal axis generator converts wind energy into mechanical energy of the propeller using the lateral force generated by its pitch when the wind blows over the blades of the propeller. The propeller will drive the gearbox to convert from low speed to high speed, thereby driving the generator to generate electricity. However, in order to make the wind turbine obtain as much power as possible, the diameter of the propeller of the wind turbine is ge...
