Session 10 Siting considerations

TOTAL TIME: 1 Hour

OBJECTIVES: To learn how to distinguish a good wind site from an inadequate site.

To understand the rules of thumb for siting windpumps

MATERIALS: Blackboard or equivalent

PROCEDURES:

Step 1: 30 minutes

Water availability, depth, proximity to users, and wind velocities and abundance are of primary concern for the siting of wind powered pumps. Discuss trees, buildings and topographical features and their effect on the wind which blows near the water supply.

Step 2: 20 minutes

Discuss other factors affecting site selection.

Ground-

Is the ground firm enough to support a tower or structure?

Can the structure be anchored?

Winds -

Seasonal variations - measure velocities Establish a projected annual wind resource availability if possible, using local individuals and government agencies.

River -

If site is located near a river, determine if flooding is a problem. Is erosion along river bank a problem?

Ownership -

Who will own, maintain and allocate water?

This should be established before project construction begins?

Other Factors -

Consider weather extremes (hurricanes, tornadoes, etc.), noise or other factors which are important to users or as a demonstration project.

Step 3: 10 minutes

Finally, discuss the use of wire lines to transmit mechanical power for use at the distant site. Use model to demonstrate the principles and note the 1/4 mile limitation using this system.
