The wave power station – is a complex technical device, located in the open water. Electricity is obtained by converting the kinetic energy of waves. The wave energy – renewable and completely infinite resource. Wave power is one of the environmentally friendly, non-waste and clean energy.
Upon receipt of electricity accounted for two characteristics of waves:
• kinetic energy;
• Rolling surface energy.
Both of these methods very productively, but they have different principles of energy and to implement them need different energy conversion schemes waves.
Converting the kinetic energy of the wave
Towards the following waves set a huge pipe, and when the tide goes into it, starts to turn the turbine, thereby resulting in a generator. Or wave displaces the air from the tube, which it fills. It begins at the exit of the turbine blades to rotate and further development of the electricity produced by traditional principles. Both of these methods are considered the most effective and are used to generate electricity.
Energy сonversion rolling surface
In this method, electric power is generated by means of floats which float on the water surface. float generator system is driven by the waves, which floats pump, and thus there is electricity production.
The very first power plant generates electricity, which converts the energy of the wave, was opened in 2008 in Portugal. The capacity of this power enough to supply electricity to about 1,600 homes.
Developers, knowing the future development of this area of electricity production, developing new technological solutions and improve the design. Australia is now being implemented highly promising wave power.
Scientists estimate that if the use of the energy of the world ocean waves, you can get up to 2 terawatts of electricity, while the United States produces electricity 1 terawatt all energy sources. The amount of energy that is produced depends on the strength of the waves, so you should still use rechargeable high power station.
Such plants are both pluses and minuses. The disadvantages include the high cost of electricity. 1 kW of electricity produced in the wave power is several times more expensive than 1 kW produced at thermal power plants or nuclear power plants. Also power can harm the ecology of that becoming in the way of the waves, they do not allow it to perform its natural function by cleansing the water surface and the ocean to participate in gas exchange. Generators of a certain type may have a negative impact on the shipping industry and displace fishermen from catching fish zones.
The advantages include that the wave power plant to protect against destruction of the harbor, harbors and coastal structures, acting as volnogasiteley. To derive power in this manner do not need hydrocarbon feedstock wave wind electricity profitable, due to several times at the specific power of the wind. And it is the most environmentally friendly form of energy.
Considering all the above, we can conclude that, despite a number of shortcomings, if they take into account and minimize all the same wave power generation is one of the most promising and underdeveloped areas of the electricity.
