14.6 Key Technologies of Oscillating Water Column Wave
Power Generator
Over the past 30 years, the technology of oscillating water column power generation has developed rapidly, the construction level has matured, and the energy
conversion efficiency has increased exponentially. Especially, the key technologies,
such as multi-resonance oscillating water column, symmetrical wing turbine, and
phase control technology, as well as backbend device and wave-gathering water,
are developing towards commercial application.
Key technologies of oscillating water column wave power generation device
need further study, including wave loads of oscillating water column wave power
generation device and survival technology in marine environment, marine engineering technology in installation construction and construction, design and operation optimization of power generation device in irregular waves, turbines in
reciprocating flow and its stable power generation technology and independent
power generation technology, etc.
China has more than 20,000 km of coastline, which contains a large number of
wave power resources. It is estimated that 30 million to 40 million kW of power can
be exploited and utilized. The future strategy should focus on the development and
industrialization of 100 kilowatt wave power generation units on the basis of a good
start of wave power generation devices for small beacons.
In addition, the oscillating float wave power generation device is developed on
the basis of the oscillating water column device. It consists of float, connecting rod,
hydraulic transmission mechanism, generator and protective device. From the
working principle, it belongs to appendage motion power generation, which is
similar to nodding duck type and wave contouring raft type. Wave energy is
converted into reciprocating mechanical energy to drive hydraulic pump by oscillating float, unstable hydraulic energy is converted into stable hydraulic energy by
energy buffer, stable hydraulic energy is converted into stable rotary mechanical
energy by hydraulic motor, and stable electrical energy is generated by generator.
Britain, United States, Netherlands, Sweden, Denmark, and China have all carried
out research on oscillating float wave energy devices.
