A wind turbine with a blade length of 54 meters rotates approximately 1,800 times in one minute and generates 1,500 kilowatt hours of electricity in one hour. The turbine rotates approximately 18 times in one minute andone revolution. generates 1.3 kilowatt hours of electricity.
For many centuries, wind turbines, like hydraulic machines, have played an important role in the development of productivity as a source of energy intended to replace human energy and animal. The widespread application of electromechanical power in modern times and the discovery of oil deposits in the Middle East in the 1950s slowed the development of wind turbines.
In the early 1970s, due to the “oil crisis”, energy shortages appeared. People have become aware of the instability and limits of conventional fossil energy supplies, so the search for clean, renewable energyhas become a key issue in the modern economy. world. an important subject. As a renewable and non-polluting natural energy source, wind energy has once again attracted attention.
The height of the fan is generally linked to the length of the blades and the customer's choice. Generally, the blade diameter of the 5000 kW fan is 100 meters or more, and. the height is more than 80 meters.
A wind turbine is an electrical device that converts wind energy into mechanical work. The mechanical work causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a steering (tail), a tower, a speed-limiting safety mechanism, and an energy storage device.
The operating principle of a wind turbine is relatively simple. The wind wheelturns under the influence of the wind. It converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. driving the wind wheel shaft to produce electricity.
Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as a heat source and the atmosphere as a working fluid.
