Abstract: Aiming at the high cost, complex structure and low energy conversion efficiency of wave power generation currently, the basic principles, new electric power generators and related advanced technology of wave power generation were studied. Different kinds of wave electric power generators such as the linear electromagnetic type, piezoelectric type and electroactive polymer type were summarized and analyzed specifically. The principles, advantages and disadvantages, and application situations of wave power capture devices including buoy type, oscillating water column type, swing and oscillation type and raft type were discussed, especially for the new dielectric elastomer generator. The future development of wave power generation technology were proposed. The results indicate that the dielectric elastomer generator which was used in the wave power generation has the advantages such as lower generating cost,simpler structure and higher energy conversion efficiency.
Key words: wave power; capture device; electric power generator; dielectric elastomer generator
