What is Wind?
What is a Wind Farm?
A Wind Farm or Wind Park is
the assembly of wind turbines which helps to generate power from wind in the
same area. Typically, a large wind farm has some individual wind turbines which
covers prolonged areas. But, the land between the turbines should be utilized
for agricultural or other purposes. It may also be constructed in
offshore area.
Design of a Wind Farm
There should be a constant
flow of non-choppy wind throughout the year having less possibility of stormy
wind in the location of a wind farm. Basically, economic wind generators need
wind speed of approximately 16 km/h (10 mph) or greater. An important
factor of turbine siting is also access to local demand or transmission
capacity.
Basically, a wind farm is
planned and designed on the basis of a meteorological wind data charts as well
as practically measuring actual wind speed of the area. In order to finance the
project, it is very important to survey the area and collect the data of wind
speed of that particular area. Sometimes, wind in local areas observed for a
year or more. Before installing wind generators and detailed wind maps
should be prepared.
Each turbine is connected to
medium voltage through a combined power system and communications network. In
order to increase the voltage of the power system, a step up transformer is
used in a substation. Installation of collector system and substation are
required to build up a land-based wind farm. A road access for each turbine is
also required in the farm area.
