The cost of a wind turbine is about 10,000 to 30,000 yuan, and the base price depends on the power of the wind turbine. Wind turbines are electrical equipment that convert wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Wind turbines typically consist of components such as a wind turbine, a generator, a deflector (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. 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 generator using thermal energy that usese the sun as a heat source and the atmosphere as a working fluid.
A wind turbine consists of a nose, a rotor, a tail and blades. Each part is important, and the functions of each part are as follows: the blades are used to receive wind energy and convert it into electrical energy through the nose; the tail allows the blades to always face the direction of the wind to obtain maximum wind energy; the rotor allows the nose to rotate flexibly to reach the tail has the function of adjusting the direction; the nose rotor is a permanent magnet and the stator winding cuts the magnetic lines of force to generate electrical power.
The power of wind energy is entirely determined by the power of the wind turbine. It is always tempting to buy a larger wind turbine, but this is incorrect. The current wind turbine only charges the battery, and the battery stores electrical energy.The amount of electrical energy ultimately used is most closely related to the size of the battery. The power size mainly depends on the size of the air volume, not just the power size of the machine head.
From the point of view of cost and rotational balance, the three-piece design is the most suitable. Theoretically, the smaller the number of blades in a wind turbine, the higher the rotation speed under power. However, considering the stability requirements of the center of gravity, three-blade wind turbines are the most practical horizontal axis wind turbines today. To put it simply, 3 leaves are easy to balance. Too many leaves make balancing difficult and expensive. Multi-leaf fans have large resistance, which will cause factors that interfere with the rotation of the blades and reduce the energy conversion rate, so choose. 3. Leaves are worthmuch better than 4 or 5 sheets.
A wind turbine is an electrical device that converts wind energy into mechanical work, which 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 main function of the wind turbine rotor blades is to capture the wind and transmit the wind force to the rotor axis. On a modern 600-kilowatt wind turbine, each rotor blade is about 20 meters long and designed to resemble an airplane wing.
