Wind Power Generation Course Presentation

 Wind turbines are power generation equipment that convert wind energy into mechanical power, which in turn rotates the rotor to generate AC electricity. Wind turbines are generally composed of components such as the windwheel, generator (including the equipment), the yaw mechanism (tail fin), tower, speed limiting safety mechanisms, and energy storage devices. The working principle of wind turbines is relatively simple; the windwheel rotates under the action of the wind, converting the kinetic energy of the wind into mechanical energy of the windwheel shaft, and the generator rotates to generate electricity under the drive of the windwheel shaft. Broadly speaking, wind energy is also solar energy, so it can also be said that wind turbines are heat-based generators that use the atmosphere as the working medium for thermal energy.

For many centuries, windmills, like water-powered machinery, have played an important role as a substitute for human and animal power, contributing significantly to the development of productivity. The widespread application of modern electrical and mechanical power, as well as the discovery of oil fields in the Middle East in the 1950s, led to a slowdown in the development of windmills.

In the early 1970s, due to the "oil crisis," there was a problem of energy shortage. People realized the instability and limitations of the supply of conventional mineral energy, so seeking clean and renewable energy became an important topic in the modern world. Wind energy, as a renewable and natural energy, once again attracted people's attention.

The principle of a wind turbine

Wind power is converted into mechanical energy, and then mechanical energy is converted into electrical energy. In a broad sense, it is a heat engine that uses the sun as a heat source and the atmosphere as a working medium for heat energy. Wind power makes use of natural energy. It is much better than diesel generation. However, if used as an emergency, it is still not as good as diesel generators. Wind power should not be considered as a backup power source, but it can be used on a long-term basis.

The principle of wind power generation is to use the wind to drive the wind turbine blades to rotate, and then through the speed-increasing machine to increase the rotation speed, to cause the generator to generate electricity. According to the current technology of wind generators, it can start generating electricity when the wind speed is about three meters per second (the degree of light wind). Wind power generation is forming a surge in the world, because wind power generation does not have fuel problems and will not produce radiation or air pollution.
