Wave energy: Wave power In the sea and the oceans by the wind on the surface of the water, the wave is produced. energy The mechanical of the wind caused by the unequal absorption of the heat of the infrared beams and the sunlight of the sun energy Gravitational potential stored in seawater stored after a short period of seawater. energy Kinery (Wave) So he gives.

The whole energy A wave distributed on the ground at about 1 Gigawat Estimated that within the limits of the general distribution Tidal energy is. Wave energy Renewable source is (Reversible energy) And usually relative to Wind energy More productive.

The energy benefits of waves

Wave energy The sea of ​​the type Renewable energy is. Such sources do not need millions of years to come and endless. Energy production In this way the contamination is not in. These power plants can be the highest in the winter energy Produce and fortunately we need more energy at such times. Small wave generators can be used in remote areas where power transmission is not affordable.

Since water is about 5 times more density than air, density Wave energy more than Wind energy And Solar energy Is and the amount energy Enhances the being for harvesting. The waves are predictable and therefore easier to predict for supply and demand.

Disadvantages of energy energy

Power produced in Wave power plants Is not fixed and depends on the condition of the sea wave. It is difficult to build and make high wave generators. Submarine cable The wave generations are interconnected for boats and ships.. In addition, power transmission through cable is also dangerous. Because the cable may be bare and the power flow into the water and endanger the seafood. By the way, this Power plants Should be made in such a way not to hurt in bad and stormy conditions.

Methods of using waves' energy

To use Wave energy Of the three designs of energy It is exploited:

The use of floating cylinders

The cylinders are made so that their most weight is in the bottom and they have a valve at the bottom.. When the waves come (۲) Closed and the average valve air (۱) Discharge, valve (۳) It is also closed and air through the valve (۴) Exit and cause the blades to rotate. When the wave goes down, a suction state is created; So the valve (۱و۲) Closed valve (۳و۴) It opens and the air enters the cylinder, causing the blades to rotate. The rotation of the blades causes turbines and generators to generate electricity..

The use of floating cams

When the wave comes, it rotates the camsses and connects this rotational movement to the generator.. In fact, many of these camshafts are connected by a rod and put the complex near the shore, these systems for the waves. Heavy waves Applicable.

Use

The drum system is something like a car tube whose walls are elastic. The interior of the segmentation has placed the turbine. The system is float on the water and the wave hit them. This blow enters the body of the tube and causes its recess. The recess of the intercourse causes the air to be compressed. As a result Compressed air It enters the other compartment from one compartment and rotates the turbines.

Wave energy converter

1. Moving object: This method of wave energy to move an object and transform it to Electrical energy It benefits.
2. The water oscillating column: A column of water is high and low in a floating pipe or floating box on the sea level, and this motion of air production at high speed that can move the turbine..
3. Compact surface: Uses water pressure changes to create compressed air within a submerged system. This pressure can become a flow of air or water and convert to electrical energy.
4. Wave Overflow Machine: In this method, the height of the wave is increased by reducing the water depth and the water is pumped up to higher height..
5. Wave concentration devices: The average level of seawater is increased at specific points by the methods of funnel -shaped structures and tall waves.

Of endless resources energy The resulting wave of wind exercise in oceans and seas. The amount energy The waves are so huge that the amount of electricity is estimated only for the countries of Spain, France, Italy and Greece from the Mediterranean Sea 2 GB..

Our country because of the specific geographical location of the beaches Caspian Sea And the beaches Gulf And Oman Sea, The ability to harvest a significant amount of Wave energy For self -sufficiency inProduction of electricity And decreased Iran's share of the world from Environmental pollution It has.

Researchers need to have widespread information such as waves, time periods to achieve the right point for installing the wave converter device , Water depth , Have the distance to the beach and the physical and chemical properties of water.
Considering this information and the use of simulator software suitable for installing the device and the number and amount of electricity generated and important factors such as the cost of purchasing and maintaining the device are calculated..
These converters that are named after Wave energy converter (Wave Energy Converter) We know in different sizes and different outputs based on the amount of parameters mentioned above.

These converters due to the depth of water and the distance to the coastline to three categories, coastal. Close to the beach and away from the beach in a long distance. Each of these areas has different characteristics that initially requires a complete atlas in this field. Atlas Not only cause integration of information, but also to attract Domestic and foreign investors It will also be.

Renewable energies in Iran

Our country of Iran has the ability to produce wave on the north and south coasts, given that it is exposed to different air fronts.. Fortunately, the depth of water in the Caspian Sea, the Persian Gulf and the Oman Sea in our country is significantly greater than other neighbors, and this is an important factor in forming appropriate waves and using other countries in the region..
