An Introduction of the Types of Wind Powered Turbines
There are two types of wind powered turbines. Modern turbines can be divided into two basic groups: horizontal axis turbines and vertical axis turbines. Horizontal axis turbines are similar to plane propellers, with two or three rotor blades fixed at the front of the tower for facing the wind. This is the most common design today. On the global market, it makes up majority of the large generator-scale turbines. Vertical axis turbine is like a large helicopter with rotor blades attached vertically near the top and the bottom of the tower, and it begins to expand in the middle.
In addition, there are different sizes of wind powered turbines for large-scale or small-scale application respectively. Single small wind powered turbines, with 300 kilowatts, can be applied in a variety of applications, including battery charging, providing power to remote farmhouses or communities, and supplying farms and industrial facilities with power. These turbines are sometimes combined with other energy sources such as diesel generators and solar photovoltaic systems to provide a reliable power source. Practical scale turbines with 500 kilowatts and large size are used to provide power to the electricity grid. These wind powered turbines are often grouped together and applied in wind field or wind power plants.
The grouping wind turbines of wind power plants are more economically in generating electricity which is enough to provide thousands of homes with power. It can also be more effective in the cost of maintaining and operating wind powered turbines.
