Sea wave energy It can be considered an energy that is still behind solar energy and wind energy. It has grown to be able to produce solar cells and commercial wind turbines for a long time. As for the conduction of sea wave energy.
Note: micro inverter modern technology system that was developed to be used with solar cells in alternative energy production By generating electricity from solar energy, sumitrapower is the leader in installing solar cell systems in Thailand.
It is not very widespread. But in the future, energy from sea waves will probably be used more. because it has a high energy potential And its energy that never runs out. In addition, it is clean energy that does not cause pollution.
The use of energy from waves is the energy that the wind transfers to the surface of the ocean, causing waves to rush to the coast and various islands. Wave power generators are designed to float on the water surface. or can be installed on the spot Using wave energy to generate electricity For this to be effective, the area must be in a zone where the waves have sufficient energy. In that area, there must also be wind power. Countries that have initiated the use of wave energy include Japan, England and Portugal.
The development of sea wave energy
Portugal opens world’s first tidal power station The Portuguese government has partnered with an energy technology company to launch the world’s first commercial wave power station. The €9 million investment by Portugal hopes to continue to become one of the world’s leading countries in renewable energy. The power generating station was officially shut down on September 28, 2008.
Working principle of electric power generator from wave energy
The Pelamis Wave Energy Converter (PWEC) converts wave energy into electricity, three large, red cylinders resembling sea serpents that float in the middle of the ocean away from the coast.
1 PWEC is divided into 4 sections, like a large snake. It looks like a bendable cylindrical tube floating on the sea surface. Each section is held together by a hydraulic coupling, which is a push rod that connects to a piston-like device contained in each PWEC. This pipe will be bent. Make the pushrod go to the hydraulic press. The work of the hydraulic press converts to electricity. and transmitted through the subsea cable pattern to the substation and then onto the next transmission line
The world’s first sea wave electric generator is in Portugal. and is a commercial electric power generation Portugal hopes to become the world’s leader in renewable energy sources. The device used to receive the wave energy looked like a large snake floating in the sea.
Wave Energy Research and Development Facility in Brazil
100 kW wave power plant with an investment of 7.3 million US dollars. It is a research and development project for harvesting wave energy. to transform the mechanical energy of the wave into electrical energy The form of a device used to convert ocean wave energy into electrical energy consists of two 10-meter-diameter circular puppet floats in the sea. Connect to the power generation system. Because Brazil’s terrain is along the sea coast suitable for generating electricity from sea wave energy.
A type of device used to convert sea wave energy into electrical energy.
There are 2 types of devices used to transform sea wave energy into electrical energy:
1. Stationary type
There are many forms of stationary use of wave energy, for example, allowing waves to hit the coast that looks like cliffs. and building a reservoir at the top of the cliff When the waves hit the shore, the sea water will enter the reservoir. When the wave passes, the water flows back into the sea. We will bring the energy of the water that flows back into the sea to generate electricity. Or allow the energy of the wave that hits the shore to cause the receiver to rock back and forth. and a wave receiver is connected to a hydraulic press to convert the wave energy into electrical energy.
2. Floating
floating wave power generation device There will be a large buoy floating on the surface of the water. When the wave moves in The waves raise the buoy and as the wave passes the buoy lowers. This is the case at all times when the wave buoy is connected to the hydraulic shaft. Therefore, the buoy acts as a continuous rhythmic compression of the hydraulic press during the time of the waves. And there is a device that converts the energy from the hydraulic press into electrical energy.
