Week 2 : Details on Optimum Position

There are three primary types of wind turbine:

a. VAWT Savonious

b. HAWT towered

c. VAWT Darrieus

For HAWTs, since cyclical turbulence may lead to fatigue failures, most of them are of upwinds.

However, for VAWTs, key advantage is that the turbine does not need to be pointed into the wind to be effective.

Installation for Small-Scale Wind Power Generation
Turbines are often mounted on a tower to raise then above any nearby obstacles.

One rule of thumb:

Turbines should be at least 30 ft (9.1m) higher than anything within 500ft (150m).

Better locations for wind turbines are far away from large upwind obstacles. A small wind turbine can be installed on a roof. Installation issues include the strength of the roof, vibration and the turbulence caused by roof ledge.

The torque ripple is relevant to the stability of turbines.

Some position may be suitable for installing small wind turbine:

1. roof
2. coast
