You have been hired to help set up a wind-powered generator to run water pumps on a cattle ranch in western Oklahoma. An important consideration is the loss of energy due to transmission. The rancher has asked you to design the generator and determine this loss for a wind power system consisting of a single wind generator and three pumps located close together but at some distance from the generator. Known Information: Transmission line resistance: 2x10-4 Ohm/m (0.2 Ohm/km) Single Pump Operating Voltage: 250 V + 25 V (pump damage outside this range) Single Pump Operating Power: 2000 W Distance from generator to pumps: 4 km Draw diagrams for the two possible arrangements of the circuit, including the generator, the transmission lines (remember that they have resistance), and the pumps. The pumps can be connected in different ways, but all need to be in the operational range given. What are the advantages and disadvantages of the two circuits? What is the best circuit design? Justify your choice. Note: the pumps can be approximated as resistors. Use the "Insert>Image>Upload Image" option to submit a screenshot or hand-drawn picture containing your answer. Make sure that it's of a high enough resolution that we can tell what your answer is when grading.

Transcribed Image Text:You have been hired to help set up a wind-powered generator
to run water pumps on a cattle ranch in western Oklahoma.
An important consideration is the loss of energy due to
transmission. The rancher has asked you to design the
generator and determine this loss for a wind power system
consisting of a single wind generator and three pumps located
close together but at some distance from the generator.
Known Information:
Transmission line resistance: 2x10-4 Ohm/m (0.2
Ohm/km)
Single Pump Operating Voltage: 250 V + 25 V (pump
damage outside this range)
Single Pump Operating Power: 2000 W
Distance from generator to pumps: 4 km
Draw diagrams for the two possible arrangements of the
circuit, including the generator, the transmission lines
(remember that they have resistance), and the pumps. The
pumps can be connected in different ways, but all need to be
in the operational range given. What are the advantages and
disadvantages of the two circuits? What is the best circuit
design? Justify your choice. Note: the pumps can be
approximated as resistors. Use the "Insert>Image>Upload
Image" option to submit a screenshot or hand-drawn picture
containing your answer. Make sure that it's of a high enough
resolution that we can tell what your answer is when grading.
