Wind power systems convert the wind's kinetic energy into electricity. They generally have three sets of components:
These components must be carefully selected to make best use of available wind resources. Keep reading for more details. Wind Turbines
Modern wind turbines generally have 3 blades to capture the wind, along with some form of yaw control to keep the blades pointing into the wind. They are divided into two categories, based upon the amount of electricity they generate:
Chesapeake Renewable Energy provides sales and service of small wind turbines for battery charging and grid-connect applications in the 1KW to 15KW output range. We are a certified dealer for Bergey Windpower Company and Proven Engineering Products, two companies that produce the world's highest quality small wind turbines. We use a detailed methodology to analyze your power needs, application and wind resources before we propose a system. This approach ensures that we understand your needs and priorities and you understands the technologies and resources available, as well as the cost. Towers Towers that support the wind turbine have either tubular or lattice construction, and are either self-supporting or reinforced with guy wires. Tubular Towers Tubular towers use sections of metal pipe that fit together to form the tower.Lattice Towers Lattice towers use sections of crossed metal bars that fit together to form the tower.
These towers are all engineered to withstand extreme forces over many years of use. In general, towers are engineered to withstand the thrust load of a specific turbine in 120 mph winds for an extended period of time. Because of this, towers are usually matched to specific turbines. Guyed towers are supported by sets of guy wires running from different levels of the tower to anchors surrounding the tower. These cables provide most of the strength necessary to support the turbine and withstand the thrust loads. In many cases, they must also be able to support the weight of someone climbing the tower to perform maintenance on the turbine. Self-supporting towers are engineered to support these loads without using guy wires, usually through the use of extensive concrete foundations. Tilt-up towers, which may be tubular or lattice guyed towers, are designed with a hinge at the base. This provides the ability to raise or lower the tower using a winch for periodic maintenance.

The
wind turbine is the core component of a wind system, because it performs the
"magic" of converting wind energy into electricity. Windmills
played an important role from the late 1800s to the early 1900s.in bringing
electricity to rural areas of the U.S.
