Description

Tidal power generation system

The present invention relates to a tidal power generation system.

In general, there are many ways to obtain electrical energy, but large amounts of electrical energy can be obtained through large power plants, that is, hydroelectric power, thermal power, nuclear power, tidal power, solar power, and wind power plants. In the case of nuclear power generation, there are serious problems with radioactive leaks and nuclear waste disposal, and in the case of thermal power generation, fossil fuels such as oil and coal must be supplied, making it difficult to deplete underground resources, and also, burning fossil fuels. Environmental pollution is also emerging as a major problem.

Recently, research on new renewable energy such as hydroelectric power, tidal power, solar power, and wind power is being actively conducted to solve the above problems.

The tidal power generation refers to a method of producing electricity using the high flow rate of seawater generated by the difference in tides, and electricity can be produced by rotating a water turbine generator with the flow of seawater. Tidal power generation is the same as wind power generation in principle in that it converts kinetic energy into rotational energy to turn a turbine, but when comparing densities, seawater is about 840 times larger than air, so the energy density can be higher than wind power generation. . In addition, unlike tidal power generation that uses the drop of the tide, it is a power generation method that uses the flow of seawater, so it is an environmentally friendly energy system that does not require the construction of dams or embankments to secure reservoirs when installing power generation facilities. Therefore, there is a need to implement technology for this.
