WIND ENERGY SYSTEM
Problem Statement
ArborWind is a leading company in design, manufacturing, sales and commissioning of highperformance stand alone and grid connected Vertical Axis Wind Turbine. ArborWind’s roots
are in finding solutions to tough engineering problems. Your group have been selected by this
company as consultant to develop new area to setup wind plant.
You need to come up with proposal and presentation for the Board Directors for the new plant
development. The proposal should conclude
-
Propose location
Wind data (meteorology)
Selected vertical axis wind turbine design
Output power predicted for a year
To develop the area, as consultant you need to suggest the company how to handle the local
residents on the area of acceptance of the new development wind plant.
Submission Part

1. Sweep area of the turbine
Before finding the wind power, you need to determine the swept area of the turbine
according to the following equations:
For HAWT:
A=π×L2
For VAWT:
A=D×H
where:
•
•
•
L is the blade length - the radius of the horizontal-axis turbine;
D is the diameter; and
H is the turbine height.
2. Calculate the available wind power
Once you know the sweep area, you can find the available wind power according to this
formula:
Pwind=0.5×ρ×v3×A
where:
•
A is the sweep area;
•
ρ is the air density, assumed to be 1.225 kg/m³ by default (you can change it
in advanced mode);
•
v is the wind speed - the typical usable range is approximately 3-25 m/s; and
•
Pwind is the available wind power.
