Glass Fibre Blade Horizontal Wind Turbine Generator 2KW 3KW 48V 96V 220V Multi Colors For Electricity

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.

The terms "wind energy" and "wind power" both describe the process by which the wind is used to generate mechanical power or electricity. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.

Small wind turbines, also known as micro wind turbines, are used for microgeneration of electricity, as opposed to large commercial wind turbines, such as those found in wind farms. Small wind turbines often have passive yaw systems as opposed to active ones. They use a direct drive generator and use a tail fin to point into the wind, whereas larger turbines have geared powertrains that are actively pointed into the wind.

Small wind turbines typically produce between 500 W and 30 kW of power, although the smaller turbines may be as small as a 50 Watt auxiliary power generator for a boat, caravan, or miniature refrigeration unit, and the Canadian Wind Energy Association (CanWEA) defines "small wind" as high as 300 kW. The IEC 61400 Standard defines small wind turbines as wind turbines with a rotor swept area smaller than 200 m2, generating at a voltage below 1000 Va.c. or 1500 Vd.c.

What is the best material for wind turbine blades?

Most blades are made of glass fiber reinforced polyester or epoxy resin. Carbon fiber or Kevlar is also used as reinforcement. Nowadays, the possible use of wood compounds, such as wood epoxy or wood fiber epoxy, is being studied.

How many blades are best for a wind turbine?
Generally, most horizontal axis wind turbines have three blades. The decision to design a three blade turbine was a compromise. Due to its reduced resistance, the single blade design is the best number to achieve maximum efficiency,hwever,one-blade design makes the whole set of wind turbine generator not stable.

How can you increase the efficiency of a wind turbine?
Doubling the diameter of turbine blades will increase the available power of wind energy by four times. Therefore, if the wind speed is low, larger diameter turbine blades are needed to obtain the maximum wind power efficiency.

Why are 3 blade turbines preferred?
For three blades, the angular momentum remains constant, because when one blade is upward, the other two point to an angle. So the turbine can rotate with the wind.

What happens if a wind turbine spins too fast?

On the other hand, if the wind turbine rotates too fast, it may cause mechanical damage; And two create a "wall" to resist the wind to safely rotate the turbine to generate electricity. Most wind turbines have a maximum speed at which they can operate normally.

Will adding more blades to a windmill make it go faster?

Larger and longer turbine blades mean higher aerodynamic efficiency. Generating more electricity in a turbine means less energy is lost when it enters the transmission system and from there into the generator.

Why do some wind turbines not turn?
But why do you see that a stationary wind turbine may not turn? It is mainly for one of the following two reasons: they are being maintained or need to be maintained. The wind is not strong enough for them to operate, or the wind is too strong for them to operate

Trend

The scope of application continues to be expanded. In addition to the traditional application of small wind turbines for the purpose of powering TV for users in the vast agricultural and remote areas, due to the soaring prices of gasoline, diesel and other fuels, and the lack of smooth supply channels, users in inland area, rivers and lakes, fishing boats, border posts, troops, meteorology, microwave stations, etc who use diesel power generation will gradually switch to wind power generation or wind-solar hybrid power generation. In addition, small wind turbines are also installed in ecological parks, tree-lined paths, villa courtyards and other places as landscapes for people to enjoy leisurely.

Due to the improvement of the living standards of farmers and herdsmen and the continuous increase of electricity consumption, the power of single unit small wind turbines continues to increase,accounting for 80% of the total annual output. As the majority of farmers are eager to use electricity uninterrupted, the promotion and application of "wind-solar hybrid power generation system" has been significantly accelerated, and the development of multiple units has become the development direction for a period of time in the future.

Wind-solar hybrid multi-unit series power generation system is to install multiple low-power wind turbines in the same place, to charge multiple large-capacity battery packs at the same time, and control the output uniformly by a high-power control inverter. The advantage of this configuration is that:

(1) The technology of small wind turbines is mature, the structure is simple, the quality is stable, safe, reliable and economical

(2) Easy to assemble, disassemble, transport, maintain, and operate;

(3) If maintenance or shutdown is required, the rest of the units will generate electricity as usual, which will not affect the normal use of the system;

(4) Multiple wind-solar hybrid power generation systems in clusters naturally become a scenic spot and a green power station without environmental pollution.
