History of wave power generation
1799, Gillard and his son in France obtained the first patent to use wave energy. 19 10, Bocchicos plessy built a pneumatic wave power generation device to provide 1 kW power for his residence. 1965, Yoshida Yoshida invented a gas turbine wave power generation device for navigation light buoys, which was popularized and became the first commercial wave power generation device. Stimulated by the 1973 oil crisis, since the mid-1970s, Britain, Japan, Norway and other countries with abundant wave energy resources have made great efforts to research and develop wave power generation as an important part of solving future energy problems. In Britain, salter invented the nodding duck device, Cockerill invented the wave raft device, the National Engineering Laboratory invented the oscillating water column device and Coventry Institute of Technology invented the mussel device. 1978, the Japanese built a wave power generation ship named "Haiming", with a length of 80 m, a width of 12 m and a height of 5.5m The ship has 22 air chambers with an open bottom, and each two air chambers can be equipped with a gas turbine generator set with a rated power of 125 kW. From 1978 to 1986, Japan, the United States, Britain, Canada and love cooperated to carry out the largest prototype test of "Haiming" at sea for three times in Yoshiko Yura, Japan. However, due to the high cost of power generation, it has not been commercialized. 1985, Britain and China successfully developed a new generation of symmetrical-wing gas turbine beacon buoy wave power generation device, and Norway built a contracted slope focused wave power station with an installed capacity of 250kW and an oscillating water column pneumatic wave power station with an installed capacity of 500kW on Oygarden Island near Bergen, marking the beginning of the practical application of wave power stations.
