How much force is needed for a wind turbine to move?

How much force is needed for a wind turbine to move?

In general, a certain wind speed is needed to produce electricity

To charge a cell phone you don't need wind power, you need to spin it at main (the biggest disadvantage of wind energy is the low conversion rate)

Wind energy refers to the rational use of wind energy. Natural wind energy

Generally speaking, the force must be greater than 10,000 Newtons to be of value (the indicator which is 8 or 10 hours per day is the amount of force required)< /p>

1 kilowatt Wind turbines need strong winds to operate

For a 1.5 MW wind turbine, the generator spins about 1,800 times per minute, generating 1,500 kWh of electricity per hour and the turbine rotates approximately 18 times per minute. This is directly related to the unit's ability.

Generally speaking, level 3 winds are valuable. However, from an economic point of viewical and reasonable, wind speeds above 4 meters per second are suitable for electricity production.

According to measurements, a 55 kilowatt wind turbine has an output power of 55 kilowatts when the wind speed is 9.5 meters per second; when the wind speed is 8 meters per second, the power is 38 kilowatts; wind speed When the wind speed is 6 meters per second, it is only 16 kilowatts; when the wind speed is 5 meters per second, it is only 9.5 kilowatts. It can be seen that the stronger the wind force, the greater the economic benefits.

Detailed information

A wind turbine is an electrical device that converts wind energy into mechanical work. Mechanical work causes the rotor to rotate and ultimately produces reciprocating output. current. Wind turbines generally consist of components such as a wind wheelenne, a generator (including devices), a director (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 thermal energy generator that uses the sun as a heat source and the atmosphere as a heat fluid. 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 energyelectromechanics 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 limitations of conventional fossil energy supplies, so 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.

< /p> < p>It depends on the starting wind speed and working wind speed of your wind turbine, both of which are listed in the manual.

Start wind speed means that when the wind speed is setlifted, the fan will produce electricity when it spins (it spins slowly although it also spins, but there is no power, I won't explain it), but the power must be very low ( because it is not the nominal wind speed), the normal is 1.8 meters/second (starting wind speed).

The rated wind speed means the fan can work normally when the wind is at least strong (it's very simple, everyone knows), the normal speed is 3-6 meters/ second

Because each manufacturer designs fans differently, their start-up and rated wind speed are also different. Please read the instructions.
