Summary of research on generator of offshore wind wave combined power generation system

Abstract

In recent years, multi energy complementary utilization has become a new trend of energy development. Offshore wind and wave energy have many advantages, such as no pollution, concentrated energy form, etc. a new wind wave combined power generation system based on two degree of freedom linear rotating generator came into being. The research status of offshore wind and wave power generation system is summarized, and the advantages and disadvantages of independently developed offshore wind and wave power generation system, traditional wind wave combined power generation system and new offshore wind wave combined power generation system are compared. The research status of rotating generator of two degree of freedom straight line as the core energy conversion device of a new offshore wind wave combined power generation system is summarized, and the feasibility of using two degree of freedom generator in the new offshore wind wave combined power generation system is preliminarily verified by finite element method. Then, the research hotspots and difficulties of this kind of generator are discussed. Finally, the main research directions of two degree of freedom generator for offshore wind wave combined power generation system in the future are prospected.
