Embodiment Construction
[0023] refer to figure 1 , figure 2 , according to the corresponding equivalent method, the complex mechanical structure is simplified as far as possible without changing its own nature, and the basic electrical components of the lumped parameters are used to describe the reference frame, excitation source, inertial , elasticity and damping. Then, different types of wave energy conversion devices with different degrees of freedom are transformed into corresponding fully electrified equivalent circuit models.
[0024] In the equivalent circuit model, there is only one "ground" in the system, which serves as the inertial reference frame of the system. The excitation source provides external force or speed for the system and is the energy source of the system. For mass elements and spring elements, they can store and release mechanical energy. As for the damping element, its function is not to provide mechanical energy to the system, on the contrary, it can convert mechanica...

The invention relates to an all-electrical wave power generation experiment system. The all-electrical wave power generation experiment system comprises a simulation circuit used for simulating a point-absorption type single-freedom-degree wave power generation device, an asynchronous motor, a permanent magnet synchronous power generator and a controller, wherein the simulation circuit comprises aphysical parameter unit of a floater, a unit for realizing interaction with incidence wave of the floater, a power take-off unit PTO and a connecting line part; the physical parameter unit of the floater comprises a first inductor (L1), a first capacitor (C1) and a first direct-current power supply (US1); the first inductor (L1) realizes equivalence through the mass Mb of the floater, the first capacitor (C1) realizes equivalence through the variable part Rho gS of hydrostatic force caused by the displacement, deviating from a balance position, of the floater, and the first direct-current power supply (US1) realizes equivalence through the spring pretightening force Rho gVproload suffered by the floater end.
Description
technical field [0001] The invention belongs to the field of wave power generation, and in particular relates to an all-electric wave power generation experimental system. Background technique [0002] With the development of science and technology and the improvement of modernization level, human consumption of primary energy is increasing day by day. Traditional energy sources such as coal, oil, and natural gas are facing depletion, and the global energy crisis has prompted countries all over the world to intensify research on renewable energy sources such as wave energy and wind energy. The oceans are considered the last treasure trove of resources on Earth. The ocean surface water layer contains huge energy, and it can be continuously replenished, inexhaustible and inexhaustible, so it has become a new research hotspot. my country's marine resource reserves are extremely rich and have high development and utilization value. The study of wave energy power generation ha...
