Wind Energy Conversion Systems (WECS) converts the energy in
moving air to electrical energy. The concept is simple and has
been adopted thousands of years ago. The wind blows and strikes
the set of blades mounted on a shaft that is ready for a
rotation.

When the blades are hit by the wind, it will then generate a
force that turns the shaft. This rotational kinetic energy may
be used for numerous varied reasons and purposes. Pumping water,
moving a saw, turning grain - grinding stones are just some of
the uses of wind energy, to name a few.

Wind Energy Conversion System is an apparatus that converts the
kinetic energy from the current of wind to mechanical energy
that are useful and can be used to run machineries like grain
mills, water pumps and generators. The following are the major
components of a typical Wind Energy Conversion System:

Wind turbine A generator Control systems Interconnection
apparatus

The following types of generators are to be used alternately by
the users of the energy power:

synchronous generators permanent magnet synchronous generators
induction generators squirrel-cage type wound rotor type

The permanent magnet generators and squirrel-cage induction
generators are most commonly used by small to medium power wind
turbines because of their reliability and cost advantages.
Induction generators, permanent magnet synchronous generators
and wound field synchronous generators are used in different
high power wind turbines. Interconnection apparatuses are
devices used to achieve smooth start, power control and
interconnection functions. Power electronic converters are
usually used to do the purpose. To provide a fixed voltage and
frequency output with a high power quality, most modern turbine
inverters are the required commutated PWM inverters. Both the
source voltage controlled inverters and voltage source current
controlled inverters were applied in both turbines.

Effective power control in certain high power wind turbines can
be achieved by using double PWM (pulse width modulation)
converters. PWM actually provides a two - direction power flow
system between the turbine generator and the utility grid. If
you want to know more on the Wind Energy Conversion System,
online information are always available. The following features
are just some of the information you can obtain from online
research: Focus on enhanced use of grid capacities and grid
support for fixed-and variable-speed controlled wind power
plants Demonstration of impede changes in the grid caused by the
coupling of wind power plants
Comprehensive treatment of grid integration that includes the
effect of power fluctuations

Discussion of profitability expectations and energy results
Control systems and Power conditioning to ensure the safe
operation of plants

Conventional and new types of generators, converters and power
electronics The use of wind energy is now rampant and is said to
be very efficient according to the users who have tested its
performance. Be one of those who have already tried the
efficiency and power of the renewable wind energy.
