The rotation of paper wind turbines is now used in wind power generation. The principle is the same: Wind turbines are electrical equipment that converts wind energy into mechanical work. Mechanical work causes the rotor to rotate and ultimately produces reciprocating output. current. It is generally composed of wind turbines, generators (including devices), steering deflectors (tails), towers, speed-limiting safety mechanisms and energy storage devices. The operating principle of a wind turbine is relatively simple. The wind rotor rotates under the influence of the wind. It converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft to generate. 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 uses the sun as aheat source and the atmosphere as the working fluid. According to the characteristics of fixed torque wind turbines and variable pitch, constant frequency and variable speed wind turbines, the motors currently installed in China are generally divided into asynchronous, synchronous, horizontal axis and vertical axis wind turbines.
What is the principle that turns the wind turbine when the wind blows
One rotation of the wind turbine can generate 1.96 kilowatt hours electricity? .
Different motors have different power ratings. When wind power is relatively stable, it can generally generate 2,000 degrees of electricity in 60 minutes, on average, it can generate 0.56 degrees of electricity per second. and a turn The amount of electricity that can be generated is 1.96 kWh. Of course, this data is not completely accurate and will be affected by the influence of wind and the stresses of the generator itself. LSolar energy technology is not sufficiently mature and has not been used on a large scale due to its relatively high level. cost.
But many people are still engaged in research in this energy field, and this energy will also bring great changes to people's lives in the future. In the future, those with low conversion rates will. harmful to the environment. There will also be negative effects on how electricity production will be gradually changed.
The principle of wind power generation
The principle of wind power generation is to use wind energy to rotate the blades of the wind turbine, then increase the rotation speed using a speed multiplier to cause the generator to produce electricity. The blades are used to receive wind energy and convert it into electrical energy.poke through the nose. The tail allows the blades to always face the direction of the incoming wind to obtain maximum wind energy. The pivot allows the nose to rotate flexibly to realize wind power. Tail direction adjustment function. The nose rotor is permanent magnet, the stator windings cut the magnetic lines of force to generate electrical energy.
As the wind volume is unstable, the wind turbine produces 13-25V alternating current, which needs to be rectified by the charger, and then the battery is charged, so that the electrical energy generated by the wind turbine is converted into chemical energy. Then use an inverter with a protection circuit to convert the chemical energy of the battery into AC 220V mains power to ensure stable use.
The windmill is designed according to the lever principle and is a unidirectional forced rotation machine. The bladesof the wind turbine are rotationally symmetrical and not axially symmetrical. When there is wind, the twisting moments generated by the blades in symmetrical positions cannot cancel each other, so part of the wind energy is retained by the wind turbine and the wind turbine can rotate.
The blades of the windmill are all inclined. Wind turbines use wind as energy. When the wind blows on the blades, it is equivalent to exerting force on the blades to generate rotational torque. Under the action of this force, the wind turbine continues to rotate.
:A wind turbine, also called a wind turbine, is an electrical machine that does not require fuel and uses wind as energy. Ancient windmills developed from sails. They had 6-8 sail-shaped canopies, distributed around a vertical axis, when the wind blew they rotated around the axis like a rotating lantern.
