Wind turbines facts how it works
How a Wind Turbine Works. A wind turbine converts the mechanical energy of wind into electrical energy using an electric turbine generator that is fueled by the spinning blades of the wind turbine. How Much Electricity do they Produce? It depends on wind speeds, the size of the blades and turbine, wind turbines facts how it works the air density.
The capacity factor for a large modern wind turbine is around 2MW. The blades of wind turbines are designed with a similar aerodynamic model to an airplane wing. The blades are designed to create an aerodynamic and rotational lift as wind passes over. Types of Wind Turbines. The HAWT is the more commonly used type of wind turbine, a style one will often see in modern day wind farms. Wind Turbine Power Class. This is a rating system used to rate the quality of a location of a wind turbine.
Higher average wind speeds bring higher power class rating numbers. Wind speed is a huge factor in the efficiency of the location of a wind turbine. Wind speed can be measured using an anemometer. Wind speed has a cubic relationship with electrical output of a wind turbine. Higher wind speeds are more desirable for wind turbines, although extremely high wind speeds can be dangerous for wind turbines facts how it works wind turbines.
The cut-in speed of a wind turbine is the minimum wind speed wind turbines facts how it works to for a wind turbine to begin to generate electricity. The speed of the tip of a wind turbine blade is important for determining the optimum number of blades that a wind turbine needs. Every point on a wind turbine blade rotates with the same angular speed.
Linear speeds of wind turbine blades are the highest at the tip. History of Wind Turbines. A windmill is different from a wind turbine because they do not generate electricity, they are were originally designed to grind grains or pump water. The first windmill converted into a wind turbine by adding an electric turbine generator was in in Cleveland Ohio, designed by Charles F.
By the end of the United States had just less than 43, MW of wind energy capacity. A huge increase from the 2, MW in the year Clearly, wind energy today is a growing resource of renewable energy. Wind turbines facts how it works Future of Wind Energy. Environmental Impact of Wind Energy. Wind turbines do not emit any pollutants during operation, however there are usually pollutants emit during the construction process.
They do not require a lot of land space for construction which is a major benefit to farms who can use the remaining ground space for farming or grazing. Wind turbines do have a few negative impacts on the environment: Advantages of Wind Energy. The single greatest advantage of wind turbine is that operation cost of the turbine is theoretically zero. This advantage is what allows renewable energy systems like wind turbines to be a cost-effective long term investment. Wind turbines produce two different types of noise pollution: Wind turbine noise can be physically and psychologically dangerous to nearby residents.
Wind Turbine Shadow Flicker. A wind turbine shadow flicker is the shadow casted by the wind turbines facts how it works blades of a wind turbine.
Shadow flickers that infiltrate nearby homes can be physically or pshycologically distracting. Wind turbines are expensive. The initial cost of a wind turbine is the greatest cost to the buyer. Eventually wind turbines can save you money from lowering the cost of your electric bill, but this make take years of operation before you see a payback on your investment. Wind Turbine Tax Credits.
