P-6. Design for special environmental conditions

Design drive system for pump installed on a 2 km high mountain. At the bottom at the altitude of 400 m there is substation available with 10 kV supply. There are opportunities to install available container at the slope at heights 800 m and 1200 m. Also near the pump at 2 km.

Propose two designs, lowest cost and highest efficiency. Compare solutions on spider diagram.

Note: cost of 1 km 10 kV 100 A cable is 1000 euro.

Given pump parameters:

• Rated flow 50 l/s, head 200 m, efficiency 81%, speed 1450 rpm
