Why Choose Wind Turbines?

For many centuries, wind turbines, like hydroelectric machines, have played an important role in the development of productivity as a power source replacing human and animal power. The widespread use of electromechanical power in modern times and the discovery of oil fields in the Middle East in the 1950s slowed down the development of wind turbines.

In the early 70's, due to the "oil crisis", and the problem of energy constraints, people recognized the instability and limited supply of conventional fossil energy, so the search for clean renewable energy has become an important issue in the modern world. Wind energy as a renewable, non-polluting natural energy has attracted renewed attention.

In the face of the growing energy crisis and environmental problems, we need to find more sustainable and cleaner energy solutions. Wind turbines utilize natural wind power to convert into electricity, emitting no pollutants and having little to no negative impact on the environment. The use of this clean energy source helps to reduce greenhouse gas emissions and dependence on fossil fuels, which is important for combating climate change and environmental protection.

Wind energy important

Principle of Wind Turbines

A wind turbine is an electrical device that converts wind energy into mechanical energy and mechanical energy into electrical energy. Broadly speaking, it is a heat-utilizing engine that uses the sun as its heat source and the atmosphere as its working medium. Wind power generation utilizes natural energy. Relative to diesel power generation is much better. But if it is used in an emergency, it is still not as good as a diesel generator. Wind power can not be regarded as a backup power source, but it can be utilized for a long time.

In addition, wind turbine generators are highly renewable and sustainable. Wind is a widely available natural resource on the earth that is not subject to seasonal variations or geographical limitations, so wind turbines can be operated in a wide range of environmental conditions without suffering from the problem of resource depletion. In contrast, traditional energy sources such as coal and oil have limited resources and serious pollution problems, and their long-term use will cause irreversible damage to the earth's environment.

Introduction to Wind Turbines

Wind power is creating a boom in the world because it has no fuel problems and produces no radiation or air pollution. Wind power is popular in countries such as Finland and Denmark. It is also strongly promoted in China in the western part of the country. The small wind power system is very efficient, but it does not consist of only one generator head, but a small system with some technological content: Wind turbine + charger + digital inverter. The wind turbine consists of a head, a rotor, a tail, and blades.

Each part is essential, the function of each part is: The blades are used to receive wind power and turn it into electricity through the head, the tail makes the blades always face the direction of the incoming wind to get the maximum wind power, the rotor can make the head rotate flexibly to realize the function of adjusting the direction of the tail, the rotor of the head is a permanent magnet, and the stator winding cuts the magnetic lines of force to produce electrical energy.

Wind turbine generator benifits

The wind turbine is unstable due to the wind, so its output is 13-25V alternating current, which the charger must rectify and then charge to the battery so that the electrical energy generated by the wind turbine becomes chemical energy. Then the inverter power supply with a protection circuit is used to convert the chemical energy in the battery into 220V AC utility power to ensure stable use.

Mechanical connection and power transfer: Horizontal axis wind turbine paddle through the gearbox and its high-speed shaft and universal elastic coupling connected to the torque transfer to the generator's drive shaft, this coupling should be according to to have an excellent absorption of damping and vibration characteristics, the performance of the absorption of the appropriate amount of radial, axial and a certain angle of the offset, and the coupling can prevent overloading of mechanical devices. Another type of direct-drive wind turbine paddle is not directly connected to the motor through the gearbox wind turbine motor type.

How to Improve Wind Turbine Reliability

Studies have shown that the ways to improve the reliability of wind turbines mainly include the following:

Technical Staff Training: First of all, we need to set up a team of engineers with knowledge of reliability theory, train engineers to gradually master reliability theory in the course of their work, and let them understand the importance and significance of reliability to the operation and development of wind turbines.

Reliability Design: Reliability engineers need to focus on reliability issues in the early stages of product design and assess the impact of design concepts on reliability. At the same time, computer-aided engineering analysis software is utilized to repeatedly design and test the product to solve the design problems, and to design a model of the highly reliable wind turbine.

Reliability Testing: Wind turbine component providers must make a formalized testing routine to ensure the reliability of accessories, and it is also essential for wind turbine prototype assembly testing. The purpose of reliability testing is to identify potential problems as early as possible and ultimately make the system reliable. Reliability tests should be carried out at several levels, especially for complex systems at the component, assembly process, subsystem, and system levels. For example, the components should be tested first and the overall test should be conducted after passing the test, thus reducing the project risk.

In system reliability testing, reliability failure reports should be generated after each level of testing and then analyzed and corrected, so that the level of reliability testing can be improved. Although this type of testing takes a lot of time and expense, it is worth it compared to the long downtime due to failures and losses caused by product instability during actual operation. In the case of offshore wind turbines, such tests need to be carried out even more rigorously.

Installation of Monitoring Systems: Wind turbine installations can use, for example, vibration monitoring and analyzing equipment or install sophisticated instruments that can detect the early signs of an emergency failure. These condition monitoring systems can trigger the maintenance process when problems are detected beyond the early warning. Therefore, predictive maintenance and condition maintenance are also important ways to improve system reliability.

Wind Power Outlook

Usually, people think that the power of wind power generation is completely determined by the power of the wind turbine, and they always want to buy a bigger wind turbine, which is incorrect. The current wind turbine is only to charge the battery, and the battery stores the electricity, people end up using the size of the electric power and the size of the battery has a closer relationship. The amount of power depends more largely on the amount of wind, not just the amount of head power.

Wind turbine for energy save

Inland, a smaller wind turbine would be more appropriate than a larger one. This is because it is more likely to be driven by a small amount of wind to generate power, and a constant small wind will supply a larger amount of energy than a momentary gale. When there is no wind, people can still use the electricity brought by the wind, that is to say, a 200W wind turbine generator can also be used in conjunction with a large battery and inverter to obtain 500W or even 1,000W or even greater power out.

The use of wind turbines is a steady stream of wind energy into our family's use of standard utility power, the degree of savings is obvious, a family's electricity for a year is only 20 dollars of the cost of battery fluid. And now the wind generator a few years ago, performance of great improvement, only in a few remote areas, the wind generator was connected to a 15W light bulb with direct electricity, a light, and a dark will often damaged the light bulb.

And now due to technological advances, the use of advanced chargers, inverters, and wind power has become a small system with a certain technological content and can replace the normal utility power under certain conditions. For example:

  • Mountainous areas can use this system to do a year-round no-cost street light.
  • The highway can use it to make a road sign light at night.
  • Children in mountainous areas can study at night under fluorescent lights.
  • The roofs of small high-rise buildings in the city can also be used for wind motors, which not only saves but also is a real green power source.

Family wind generators, not only can prevent power outages, but also increase the interest of life. In tourist attractions, border guards, schools, troops, and even backward mountainous areas, wind turbines are becoming a hot spot for people's purchases. Radio enthusiasts can use their technology in wind power generation for people in mountainous areas, so that people watch TV and light electricity with the city synchronization, but also to make their labor rich.

The choice of wind turbines is also conducive to sustainable economic development. With the advancement of technology and the expansion of scale, the cost of wind power generation is gradually reduced and has high competitiveness. Moreover, the development of the wind energy industry can create more employment opportunities, promote the development of related industrial chains, and inject new vitality into economic growth. In summary, the choice of wind power generators is not only in line with the concept of environmental protection, but also has economic and social benefits, and is one of the important directions for future energy development.
