Korea currently has the highest energy source unit (consumption energy per gross domestic product) in the world, and the dependence on energy abroad is 97% of total consumption (September 20, 2004), and most of them are from fossil fuels and nuclear power generation. will be. Renewable energy is only less than 2% of total consumption. As such, the necessity for the use of energy in consideration of the current environment is rapidly emerging, and the development of renewable energy is not an option but an essential situation.

Solar, wind, and tidal energy is being developed as a renewable energy for this purpose, but solar heat can only be collected during sunshine hours, and the efficiency is reduced to 10% in the morning and evening, and the efficiency is reduced by 20% due to bad weather. In the case of wind power, the efficiency is low due to domestic geographic conditions, it is not regular, and it is not suitable for power generation.In the case of tidal power, it is considered that renewable energy is suitable for domestic application together with wave energy. The problem with using a car is that not enough energy can be obtained.

On the other hand, wave energy can be said to be infinitely clean energy that is not depleted no matter how used together with solar energy. In addition, research on available energy extraction methods has been conducted for a long time due to high expectations as an alternative energy source for the future of mankind, and has many advantages, and active development is being developed in developed countries.

In addition, among the existing power generation systems, the highest generation efficiency system is aberration power generation. The aberration power generation converts the potential energy of water, that is, water head difference × flow rate into electrical energy with an efficiency of 95% or more using aberrations (Francis aberration, Felton aberration, etc.). However, it is difficult to secure potential energy with predictability and sustainability, which lowers operating efficiency and costs a lot such as dam construction costs.

As one of the powers for implementing the aberration power generation, the wave energy is an infinite clean energy that is not depleted. The power generation device using the same is installed far enough from the coast, and is more predictable than the solar energy or the wind energy, Profitability is high because it can be used for dispatch. In addition, the strength of wave energy is that it has a high power density, and it is easier and cheaper to integrate wave power including wind energy existing in the ocean.

Due to the above advantages, generators using wave energy have been developed in various ways, but the efficiency is low and the installation cost is very high compared to power generation, which makes it difficult to put them into practical use. The problem is that the structure is also very complicated and expensive to maintain and repair.
