The oscillating water column (OWC) wave energy conversion device has the advantages of simple structure, reliable working performance, and long device life, making it one of the mainstream wave energy generation devices. This article analyzes and summarizes the development process of OWC technology, giving a comprehensive introduction of various OWC technologies and their development trends. The OWC devices are divided into fixed type OWC and oscillating type OWC based on the different working states of the air chamber. The fixed type is further divided into shore based fixed type, nearshore fixed type, and floating anchor type. According to the different working principles of OWC devices, the research achievements related to OWC technology are classified and discussed, and the development trends of OWC technology are summarized. The advantages and disadvantages of three different air turbines in the OWC wave energy conversion device are analyzed, and an efficient and reliable dual unidirectional turbine system is introduced. Finally, three suggestions are proposed to improve the efficiency of OWC power generation, and the development prospects of OWC technology are prospected.
Key words: wave energy; oscillating water column; air turbine; air chamber
