| Abstract: |
| In recent years, the multi-energy complementary utilization has become a new trend of energy development. The offshore wind energy and wave energy have many merits, such as no pollution, concentrated energy form and so on. Accordingly, a novel WWCEC(Wind-Wave Combined Energy Conversion) system based on two-degree-of-freedom LRG(Linear-Rotary Generator) emerges as the times require. The research status of offshore wind and wave energy conversion systems is summarized. The advantages and disadvantages of the independent developed offshore wind and wave energy conversion systems, the traditional WWCEC system and the novel WWCEC system are compared. Then, the research status of two-degree-of-freedom LRG that is the core energy conversion device of the novel offshore WWCEC system is summarized. Furthermore, the feasibility of two-degree-of-freedom LRG applied in novel WWCEC system is preliminarily verified by finite element method, and then the research hotspots and difficulties of the generator are discussed. Finally, the main research directions of two-degree-of-freedom LRG for WWCEC system in the future are prospected. |
