Problems solved by technology

[0004] Due to the uncertainty of the direction of the waves, the operation efficiency of the transmission wheel is very low, and it cannot be floated on the sea for a long time to generate electricity; in addition, the generator is prone to gaps and pauses during the interval between waves, resulting in intermittent power generation and poor power generation continuity
Therefore, the key issues of ocean wave generators are the efficient conversion of energy and the improvement of capacity. In the prior art, some switch reluctance linear generators are used, and some permanent magnet synchronous linear generators are used. The former has low cost and low efficiency, while the latter high efficiency and high cost

Abstract

The invention discloses a synchronous reluctance-type linear generator drive-based wave generator, which comprises an upper floating plate, a lower floating plate and a plurality of cylindrical synchronous reluctance-type linear generators, wherein the plurality of cylindrical synchronous reluctance-type linear generators are distributed between the upper floating plate and the lower floating plate; and each cylindrical synchronous reluctance-type linear generator comprises a short primary and a long secondary. By a multi-motor distributed structure, a few of permanent magnets are inserted into secondary reluctance slots of the synchronous reluctance-type linear generators, so that the advantages of the synchronous reluctance-type linear generators and a permanent magnet linear generator are well combined; the capacity of single generator is reduced; furthermore, the permanent magnet is relatively small in dosage and low in cost; modularization is easy to implement; and the wave generator is suitable for wave power generation and is also suitable for an active electromagnetic damper, an oscillating system and the like.

Description

technical field [0001] The invention belongs to the technical field of ocean wave power generation, and in particular relates to an ocean wave generator driven by a synchronous reluctance linear motor. Background technique [0002] Environmental pollution and energy crisis are two common themes in the development of the world today. Vigorously developing wind power generation, tidal power generation, geothermal power generation and other new energy power generation methods, and realizing the change of energy conversion mode and the improvement of utilization rate are an important means to solve these two problems. It has a role that cannot be ignored, and has significant economic and social benefits. The movement of ocean waves is non-stop, and it will generate a lot of kinetic energy. Using the movement of ocean waves to generate electricity can save non-renewable energy, and the power generation process is environmentally friendly and does not pollute the atmosphere. The...
