The length of the blades should be judged according tothe installed capacityof the wind turbine, such as V80, V52 and S70. The blade lengths of the three above. the models measure 39 meters and 25 meters, 34 meters respectively. The installed capacities are 1500, 850 and 1500 respectively. Therefore, the length of the blade should be judged according to the actual situation.
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 wheel rotates under the influence of the wind. Elle converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. by 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 heat source. work.
For many centuries, wind turbines, like hydraulic machines, have played an important role in the development of productivity as a source of energy to replace human and animal energy. 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 became aware of the instabilityity and limits of conventional fossil energy supply, so that the search for clean and renewable energy has 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.
