According to the principle of H-type wind turbine, the speed of the wind rotor increases faster (the torque increases faster), its power output increases faster accordingly, and the production curve of energy becomes full (as shown below). Under the same power, the rated wind speed of the vertical axis wind turbine is lower than that of the existing horizontal axis wind turbine, and it generates more power when operating at low wind speeds.
How many kilowatt hours of electricity are produced by wind power in one turn?
This is a resistance wind turbine, which relies on the difference between the resistance of the windward side and the leeward side to obtain power. The greater the difference, the greater the efficiency. Of course, the higher the system (streamlined and continuous shape, avoids loss of air disturbance energy), the greater the rigidity of the system.t big, more. thin rotation axis, friction resistance (small friction circle), the linear speed is always lower than the wind speed, the transmission inertia is small, and the speed stability is not good, can be improved by a mechanical system such as a flywheel. Effectiveness is related to the resistance area and the smoothness of the surface.
A wind energy revolution produces approximately 0.1 kilowatt hours of electricity.
At rated speed, a 100 kW wind turbine generates 0.1 kWh of electricity per cycle. When wind power is sufficient and stable, a 2 MW direct drive wind power generator generates electricity every 60 hours. can generate 2000 degrees of electricity in one minute. It takes 3.5 seconds for the fan blades to rotate once. Wind turbines between 50 W and 300 W are 12 V, wind turbines between 300 W and 800 W are 24 V wind turbines and theWind turbines above 800 W are generally wind turbines above 36 V.
Wind turbines are electrical equipment that convert wind energy into mechanical work, which drives the rotation of the rotor and ultimately produces energy. alternating current. Its operating principle is relatively simple. It is a thermal energy utilization generator that uses the sun as the heat source and the atmosphere as the working fluid. As an energy source replacing human and animal energy, it plays an important role in developing productivity. Wind power generation often has no fuel concerns and generally does not produce radiation or air pollution.
Principles of wind power generation
Generator types include asynchronous, synchronous, horizontal axis and vertical axis . The principle of wind energy production is useduse wind power to turn the blades of the wind turbine, then use a speed multiplier to increase the rotation speed to encourage the generator to produce electricity. The blades are used to receive wind energy and convert it into electrical energy through the nose, and the fin keeps the blades facing the direction of the incoming wind to obtain maximum wind energy.
The rotor allows the nose to rotate flexibly to adjust the direction of the tail. The nose rotor is a permanent magnet and the stator winding cuts the magnetic lines of force to generate electrical power. Due to the unstable air volume of the wind turbine, the output of the wind turbine is 13-25V alternating current, which needs to be rectified by the charger, and then the battery is charged, so that the electric energy generated by the wind turbine is converted into chemical energy.
