When oil gradually runs out from the earth, humans will have to find new energy sources to replace wind energy, which would be another option. Because the wind is generally not bought, it is clean energy that does not cause harm to the environment. and never run out. At present, many countries have wind power plants to use.

How does a wind turbine generate electricity?
Everyone already knows that motors and dynamos have opposite working principles. is a modulator that converts electrical energy into mechanical energy The dynamo converts mechanical energy into electrical energy.
Likewise, fans and wind turbines perform opposite functions. is that the fan converts electrical energy into mechanical energy Wind turbines convert mechanical energy into electrical energy.
Components inside the wind turbine
The motor and dynamo have the same essential components. is that there is a part that serves to create a magnetic field and the part of the coil rotates in a magnetic field
Therefore, wind turbines which produce electricity have components like a motor or a dynamo. But there will only be gears to increase the rotation of the generator faster.
wind power in thailand
Wind is an energy source that has been used for over 4,000 years in Thailand. Wind energy is considered an energy that has been used for a long time. It is mostly used to bale water into agricultural areas such as rice fields and salt fields, etc. 99 However, the physical conditions of wind power generation It depends on the following factors:
1) has a high wind speed
2) The wind does not fluctuate.
3) There is a continuous stream of air.
Almost all wind power in Thailand is used for water pumps. The main obstacle to the development of wind energy is The wind speed is slow and intermittent.
wind farms in Thailand
wind farm It is a group of wind turbines in the same location that are used to generate electric power. large wind farm Hundreds of wind turbines may be assembled. and covers an area of several square kilometers Turbine installation area can be used in agriculture
Huay Bong Wind Power Project Nakhon Ratchasima Province
It is a wind power generation project of a private company. Farmers’ land leased for the construction of wind turbines The project consists of a large wind turbine of 90 tons, each ton has a height of 99.5 meters and a diameter of blades of 101 meters, capable of producing 350 million units of electricity per year. The Electricity Generating Authority of Thailand (EGAT) is the purchaser of electricity.
Electricity generation system from wind turbines in Thailand
There are many wind turbines in Thailand. But here we will talk about large wind turbines of the Electricity Generating Authority of Thailand with the capacity of about 1.25 – 1.5 megawatts per turbine located at Lam Takhong Dam, Nakhon Ratchasima Province and at Hua Sai District. Nakhon Si Thammarat Province The wind turbine at Lam Takhong Dam, Nakhon Ratchasima Province, has a capacity of 1.25 megawatts each.
Additional information Wind turbines at Lam Takhong Dam Nakhon Ratchasima Province can produce about 4.6 million units of electricity per year, replacing fuel consumption by 11 million liters per year.
Electricity generated from wind turbines will go through a Grid Connected Inverter or Grid Tie Inverter for Wind Turbine to convert the direct current generated by the wind turbine into alternating current to sell the generated electricity to the Electricity Authority.
This wind power plant In addition to responding to government policies By using the renewable energy that exists in the country to be highly beneficial in generating electricity to the people in the area. It will also be a learning center on wind energy development for electricity generation for students, students and the general public. Including the outstanding windmills will attract tourists to visit this area. and help generate income for the villagers in the area
The largest wind farm in the world
The largest wind farm in the world at this time is Raheenleagh Wind Farm in Ireland Which has 200 wind turbines with a total power generation rate of 520 MW, including the construction cost of about 24,000 million baht, but is about to be broken by Scotland. Because Scotland is about to build the world’s largest wind farm. There are 339 wind turbines with a construction budget of 220,000 million baht. When the construction is complete, it will produce about 40% of the country’s electricity demand.
